Let's see ... I have a pair of Quantum 2s that I'm currently working with a third cabinet to convert to a mirror-imaged pair. There's also a pair of Reference Studio Monitors and RSbs (the next model down) in use as rear channels for the former and a bedroom system for the latter. I've also an extremely rare pair of ES-1 electrostatic headphones with the ME-10D energizer.

I'm a bit lacking for pictures, but here are my Quantum 2s in my system as it was way, way back in September 2004. Very much has changed since then as this was my first foray into good audio.
http://i30.photobucket.com/albums/c301/jpvanson/System%20Pics/Quantum2old.jpg
The Q2s weren't fully operational at the time thanks to broken tinsel leads on the domes, but I was using the Watkins woofers as stereo subwoofers for the Magnepans. It was an excellent combination as Watkins bass is just as tight as it is deep.

And a picture of my pair of ES-1s. I've been having a bias voltage problem, so they're not working yet. I'm not going to give up on them, though.

These are early pics when I first received these, so please pardon the holy woofers. So, pics are "as purchased" from an Ebay seller in Toronto for a very reasonable price. These were one owner speakers, purchased for 1800 $CDN in the late the 70's I was told.

Woofers have since been refoamed and the diaphragm replaced in one Emit tweeter. Still have to purchase a power resistor for the Midrange driver xover circuit in one speaker. Have removed, cleaned and re-installed the control pots in one speaker (currently have the woofer out to do the resistor). Will do the pot cleanup when replacing the resistor in the other good speaker so it matches the resistor in the broken one.

The significance of this next pic is that there is no rear Emit Tweeter on the upper rear panel. Some versions had one here. That round piece of cloth covers a port that I "think" goes to the back of the Mid-bass driver, but needs to be confirmed. It's a design feature I would like to understand more about (for another thread).

Junkaudio,
I always have a difficult time describing the sonic aspects of loudspeakers as well. I can say this though, the RS1, RSII's and RSIII's are known for great crossovers. The great aspect of them is that they have a very steep octave rolloff which forces the appropriate signal frequencies to the correct drivers without overlaps. It is the overlaps that create a muddier sound in that a driver is handling a portion of a frequency that it is not best suited for, oftentimes driving them past their designed limits. That is maybe why they sound fast to you, because the steep rolloff provides a 'fast sound'.
Vito

BTW. Nice pictures yall. I will get some up soon.

I have a set of RS 1.5's and love them. I was going to sell the drivers and crossovers to JP and as our talking back and forth progressed my curiosity was raised and I wanted to hear them. Well, I feel bad for getting JP's hopes up but I sure did discover a great speaker that I had owned for around 4 years. Glad I took the time to put them together and have a listen. Here are a few pics of the ragged out cabs. I have the drivers complete but am still using the cabs. The pics can be seen here: http://audiokarma.org/forums/showthread.php?t=54521

I have 2 sets of Quantum 3s ,both work excellent and have had the woofers refoamed an d I have done some tinsel repairs on the midranges.1 set I redid the crossover to allow biamping.The other set has a hole someone cut in the front of cabinet to install a Hpm tweeter when the emits went bad.I installed emits and disconnected the other tweeter.Cannot see it behind the grills.I also have some Quantm jrs and 2 sets of WSC 1a's.These are the original speakers that Wlliam Watkins designed for the watkins woofer before he sold his design to Infinity.They are 3 way with paper cone tweeters and mids with the dual voice coil watkins woofer.Exceptionally fine speakers .I also have some rs8a in my living room for home theater setup.Hopefully I can get some pics later.

I have a set of Quantum 2's and a set of Quantum 3's. I have not heard better sound in a home setting than the Quantums. For home theater, I use the Quantum 3's as the main speakers & ARLSTII's for surround driven by a Pioneer 1014X Receiver, and a single AR3a for rear surround and Dayton 15" Infinite Baffle sub both driven by a Hafler DH500.

Would like to incorporate both the Quantum 2's and 3's in the system, but I have a wife. She accepts the AR's for surround, but the Quantums are too large.

bocoogto, do you have the Q2's doing duty somewhere? Actually, I think the Q2s are a handsome piece of furniture. I think they will look quite nice in the living room once I get them set up (they have that monolithic look :D ). They will replace a stacked set of Mach 2 and HPM-60.

I have Infinity's first product, the Servo Static 1 (first produced in 1969).

This is my first attempt at a picture post; here goes:

The panel (I have 2) is missing 4 tweeters and is upside down (the picture is upside down too).

Each panel had 4 midrange electrostatic panels and 5 electrostatic tweeters (blue RTRs).

The Crossover/Sub amp has outputs for midrange and tweeter amplifiers and it has volume for bass and treble.

The subwoofer, the first servo sub, was 18" in diameter, inside a 2' cube.

Mine are Brazilian Rosewood (It wasn't in danger then!).

What are those dark brown dudes holding up the efficiencies? :scratch2: AR somethings??

Those are a little strange... The drivers are old 15 inch Jensen Dualax (15 inch with a whizzer cone... 16 Ohm... early 60's???) and the cabinets are Idunnowhat. They have part of a paper label that says Rockford Illinois... The cabs have a cutout for a big horn (4"by10", I think) that is covered on the inside with a plate. They are also "ported", actually a slot shape. I was told that they where initially bought as a kit and "built" by my friend's uncle. The sound pretty sweet, but I'm waiting for my first tube score to give them life again.

All I have are a couple of pairs of RS-2001's pulling surround duty, a pair of Qe's looking for EMIT's and Infinity in my new car. :D I've been trying to get ahold of a pair of Column II's that my brother has in Nevada. Has some weird conical tweeter on the top.

Column IIs have a Walsh driver for the tweeter. I really liked it/them. Same driver as the Ohm, but not full range.

No, the Q2's and a pair of RSIIIA's are in storage. The RSIIIA's really sound great, but need woofers refoamed. Maybe they would be a better choice for home theater than the Q2's or Q3's after I get my IB subwoofers working right. The RSIII's don't go as low as the Quantums, but would probably put out more sound level. The accuracy of upper bass, mid, and highs is very good. Either pair, the Q2's or RSIII's are are too good for garage speakers--I use a pair of AR2a's in my garage/workshop now.

Don't know what to do about the home theater now. Maybe you have some ideas.

Hi Army,

While i have nothing against SS, ill always perfer the sound of toobs VS transistor...i have no idea why.

But the Sun 2a3 was paired with the adcom and primus becos all 3 components have fantastic synergy, and the Primus has crazy bass in this setup. I mean room shaking, chest thumping, plaster peeling bass! ( ok...maybe not that crazy ) But i was shocked when i heard what the 3.5Ws could do with the Primus.

Im not joking!

Grainger, so you do still have your Servo-Stats. What happened to the tweeters? Have you considered attempting to repair them?

Since others have put me to shame on pictures, I might as well post a quick pic of one of my RSMs and same for the RSbs. Odd, Infinity made some quite nice looking speakers with Rosewood and Walnut, but then decided to sell these ugly buggers with their Oak veneer and brown texture painted baffles.

JP,

I still have the Servos. The pictures posted are from the day I posted them. But they have been "broken" for quite a while. :tears:

Back in the 70s I was the servo repair guy in Atlanta. I would take parts out of mine and repair customer's units. Then wait months for replacement parts. :nono: :nono: :nono: :nono: :nono: I equate that with biting the hand that feeds you.

They (Infinity) were smoking dope at work back then. :nono: That is first hand knowledge, not a slap at the guys in California. But mine have a transistor out in the servo amp, I have found a replacement, but haven't bought it. The tweeters went into my brother's Infinity 2000As. He never replaced them either.

I have a stack of midranges that may or may not work. Some day I will get a wild hair and start vacuuming them and checking them out.

Thanks for asking.

You're talking about the RSb picture? The previous owner didn't know about refoaming at the time and chose to 'repair' the rotten surrounds with latex. It seems to have worked as a short term fix, though at the cost of much bass. However, the foam has continued to rot underneath, so the latex is starting to float above the remnants of the old surround and will likely part from the cone shortly.

Missing the original woofers, guy I got them from said he dumped the woofers cause they were rotten on the outside.....AHHHHHHHHHHHHH!!!! :bash: Anyway these were wired wrong inside and if you look close the tinsels are shot on the mids. Other than that they are coming along fine.

Charivari

03-30-2006, 12:34 PM

Sicman, those cabinets look in awfully good condition, so I'd say they're definitely worth getting going. The broken midrange tinsels are notorious for breaking, but if you're patient and have a steady hand, you can repair them (http://audiokarma.org/forums/showpost.php?p=407666&postcount=13).

The pots are very good in these, they only needed little cleaning. Must have been in a dry environment. Yeah it's a shame the woofers are missing. I had to replace one of the tweeters, it was toasted. Found an 8 amp fuse instead of a 2-3 amp in the one that was fried.

Cases are supurb for the age and haven't been cleaned up yet.
I saw the posts on fixing the mids, may try it, or send em out or hopefully find replacements. Speakers work now except for the mids.

What is your current abilities with jpegs? Do you have and/or have used photo editing software?

If you can get your jpegs resized to 800 X 600 pixels, that is the first step.

i guess this is kind of a thread hijack, but i don't care. i'm 'using' kodak easy share; it stores gigantic screen filling raw images. i think i have figured out how to get them shrunk but haven't the slightest idea how to precisely get 800x 600. seems far too complicated -- seems like you should be able to click something, get a menu option list, click what you want and be done with it w/o having to do a lot of hunting around. i have gone through the attachment process a zillion times, and always find an entire 'album' being attached, rather than just the one i want. or, when i think the image is sized correctly, i find it isn't.....
As with most things in life, if you keep fiddling with it, you'll eventually have it figured out. The attachment limits for AK are 900x900 pixels and 200kb file size. So, you needn't resize the pictures precisely to 800x600.

However, there is a quick and easy way to meet both size limitations with Windows XP. Just go to File, Save As in your Kodak program and save the picture to your desktop in JPEG format (there should be a little menu underneath where you put the file name that allows you to choose the saved format). Then, right click the icon for your photo and select from the context menu "Resize Pictures." Another window will pop up with several possible image sizes, click the 800x600 option and OK. Windows automatically chooses a lower quality compression algorithm during resize so your finished picture will not only be of the proper resolution, but also of sufficiently small size to use the "Manage Attachments" option in your Advanced Post Reply.

Or ... you can use Photobucket to upload your raw images after you have saved them to a convenient location, such as Desktop. Too large of images (greater than 512kb, iirc) will be automatically resized when you upload them to an album. After that, just follow the instructions to copy the image location and paste it into your reply and use the [ IMG] [/ IMG] tags.

Good luck,

I grew up listening to the big Altec Lansings but I like more highs than the horns produced.I ran Jensen 15's for a while which were good speakers, if a little sloppy on bass.I have not seen them mentioned anywhere.Traveling for a living,I went in every stereo shop in three states ,before the internet and big box stores destroyed them.The Kappa series had a brightness without sacrificing the bottom end that I just liked.A lot of the opinion on speakers is more nostalgia and the type of sound that one has become accustomed to.Spending more time critiqing your equipment than enjoying the music is a bad thing.As they say IM very HO.

Nice collection Mywifespissed. I too want a pair of QLS. I keep my eyes peeled for something on the East Coast, but whenever they do pop up, it is always on the West Coast with high shipping costs. shipping something that rare through normal shippers scare me with the high risk of damage, plus the cost of the shipping usually puts it out of reach. I am probably fortunate, because like you I really have enough already, but just can not resist wanting more. again, nice collection that you have there.

How interesting.... some very quick nice feedback. I found this discussion after posting here and there for years over at the infiinity classics area. I think that's a terrific area, but the discussion seems to have waned.

I am listening to Pet Sounds, an interesting CD recent version, because it includes all the tracks in their original mono state, and then all of them in stereo.

The comment about a large room to let the speakers breathe seems to be true. Additionally note that since it's a concrete dome, the wall behind, and the ceiling above is concrete, resulting I suppose in some unusual audio aspects? The ceiling arches upward.... a visitor called them cathedral-type ceilings... the place isn't that big, but he had a point, in terms of shape, and a certain unexpected space (the whole place is underground, technically, so visitors are surprised when it has some sense of relaxed space and some (but not enough) light.

I would have to get very low marks in terms of audio optimization. I am clueless as to electrical technical specifications, and so I just try to enjoy the equipment and, as long as it's working and playing music in a way that fills the home with sounds I want to hear, I try to let it go at that. Long-term, I do think I would like to try a different crossover and-or preamp setup, to try to see, perhaps just out of curiousity, if I could fill in the middle part of the sound a bit better.

As an experiment one quiet Saturday, try reversing the positions of your woofer and mid-tweeter columns, meaning move the woofers to the inside and the mid-tweets to the outside.

I have a set of Betas, which are similar in concept. I found that they need at least 10' between the mid-tweeter columns in order to throw a soundstage. The woofer placement isn't nearly as critical.

Just a suggestion, and I'd be interested to hear if anyone else has similar experience with Infinity 4-column systems.

ok, I'll try it sometime. I also got another suggestion by private email on some other placement issues. I'm really not that fanatical though. For a person who owns low WAF speakers, I'd give myself a very low rating in terms of my inclination to get the most out of them. Experimenting a bit is fun, though, I must admit.

were monitor juniors. flat from about 30-20k. sold em for rogers LS3/5As, bought another pair to use as subs for the rogers. all in all, it worked pretty good but the rogers had a bass hump that prevented them from mating seamlessly.

i fist lusted after 2000As, then my friend had holosonics, sold em, got 1001s, and some POS1s (great name for a speaker, eh cary?) for the bedroom.

i heard various incarnations of the servos, and another friend had RS1Bs and replaced them with apogee grands.

and of course i heard the QLS and QRSs at music and sound in woodland hills calif as well as again the servos at the factory.

being in socal has its benefits.

Got three pairs.

Listed in order of purchase:

1) Infinity Reference E-L's. Bought these new in 1992. Originally used them with a Sony STR-AV710. Had used them with other Sony receivers as well. Last receiver they were used with was a STR-GX59ES as main speakers. Currently having one of the woofers refoamed, then will press them into service with an old STR-VX4 and a CDP-491 as a system for our upstairs bonus room.

2) Infinity SM155's. Bought these used from a friend in 2002. Run them with my STR-AV910 receiver. A bit large for my room, but great sound. Am willing to put up with the size to have them. Had to replace one of the tweeters when I got them. Friend's wife blew it out somehow.

3) Infinity RSa's. Found these yesterday at a thrift store. Paid $35.00. One is missing the fuse for the crossover and may have either a dead EMIT tweeter or a bad crossover. Going to swap the tweeters between the speakers and see if the problem moves to the other speaker. Previous owner painted them gloss black and didn't do a very good job, so I'll have to strip them and restain the cabinets. Not sure if I'll do them in the original light oak, or do them in a rosewood color. Black doesn't go to well with the brown cloth on the grilles. Currently have these running off the GX59ES in our family room.

;-) tee hee

Did a little more research... Looks like the crossover must've blown, taking the EMIT out with it. New fuse, no high frequencies. The Ribbon on the EMIT is damaged, and tried swapping in another tweeter without anything changing. Guess I'll be replacing the crossover and the tweeter. Other than the lack of high frequencies from the right speaker, the pair of RSa's sound great. Going to try the shop that will be refoaming the woofer from one of my E-L's and see if they have some parts lying around that are good. If I don't have luck, I guess I'll be doing the eBait search, among other online methods.

Newbie here, first post and all.

I've been an Infinity-phile since the 80's. I purchased a set of RS-4Bs in 1988. Got divorced in 1990, and the deal was I had to buy a pair of speakers for the ex in order to keep he 4B's. Well, in the process of shopping for replacements I came across a one-owner pair of RS-IIIB's at a very attractive price. So, I jumped all over those (MUCH better bass extension), and left the 4B's with the ex. I'm still using and loving those IIIB's today. When I eventually upgrade someday, I hope to get a pair of Prelude MTS's. Now, if I can just convince the missus that I...err...WE can afford them... :no:

Pacolam - Wow, what a great collection!

You've got a pair of the 1990 Modulus, which were B rated in Stereophile. I'm interested to know what you think of them compared to the other larger Infinities?

Oh, and welcome to AK!!

Hello Negotiableterms,

I'm a beginner of here, it was the first time I post my pictures here.

There are some difference of Modulus (90 ver) compare to the other Infinities, because of the "time tech." I mean the mid/woofer a little bit behind the emit.

It makes the emit perfect match to the little mid/woofer, two drivers are in the same time same phase to my ears, so the sound is very smooth.

Not enough bass because it designed to use with subwoofer. I try to use RS 4000's 8" woofer be a pair of sub woofers, with active crossover, the sound is much better than only a pair of little Modulus. But they're not perfectly match, I think the original Modulus sub woofer will mix better.

Long time ago about 199x, I owned a pair of reference 50, 3 ways, the tweeter is emit-r, is good in that price, compare to the Modulus, the Modulus's mid and high are better and smooth, human vocal is better also.

RS 4000, the woofer is good, the emit is excellence, but the midrange unit sounds not match each other, finally I found a reason why. The sound and the phase (+ -)of mid driver unit, is opposite to the emit and woofer, I try to change (- +) and reconnect it, is much better then before. But Modulus still better because of the difference quality.

I check the inside connection of RS 4000, the wire connection colour is right, nothing wrong but the midrange comes out opposite phase sound in right connection, I don't know why?

I found some strange things of some Infinity models too, the phase are not all correct in each driver units, even I check the inside connection, it seems right, the sound of all driver unit come out are not in the same phase together, so I need to check and reconnect the oppsite(wrong) one.

I have 3 pairs of Infiniies that the phase have no problem:
1) RS 2000
2) Modulus 90 version
3) Ref 50 (sold out already)

And I have 3 pairs of the other models that I owned, I need to do the reconnection for them.

Aha! So I'm not alone in this, though I never thought that I'm the only one who can hear incorrect phase between drivers. The midbass drivers on my Quantum 2s are supposed to be connected out of phase according to the crossover schematics, but the sound in this frequency region is very off compared to my other very good speakers (Tannoys, Magnepans, etc). When I connected the midbass driver to the correct phase both according to the wires and to observed cone motion, the sound is much improved. Yet, others were not at all hesitant to proclaim my change to be incorrect. :dunno: Interestingly, my Q2s are a very early pair (one off from those pictured in the brochure) and were connected opposite to the schematic, only the later variations were connected out of phase as I discovered in my mirror-imaging project.

I say, connect the drivers how they sound best, though preferably so everything is properly in phase. Manufacturers are not immune from messing up their wiring (Bozak was notorious for mislabeling the midranges in their 302As making for most units being connected out of phase), so if they sound better to you connected in opposition to the schematic, then so be it. Frankly, I believe the schematics and subsequent wiring to be a marketing gimmick -- makes them sound more exciting in the short term and makes for artificial imaging, such as with the Wilson WATT/Puppy 7 -- and have no quarrels with making the change.

You're gonna need a real workhorse for that!

Vito, you mentioned a P/L 700. At 1.4 ohms, will it still be stable? To go that low, I'd think of looking for something more like an autoformer Mc, or one of the real high-end behemoths, like a Threshold or Audio Research D-400/2. Something that weighs at least 100 lbs.

Negotiableterms,
Yes, very much so. I have six Phase Linear 700's ATM. I have been using these amps to power My RS 4.5's and my RSIIA's, along with some JBL's that I have. I have been using Phase Linear power amplifiers for 26 years now and swear by them. They have never had any problem at all. The RS 4.5's are the real test as each cabinet has two 12 inch Watkins woofers to drive. I usually play music just under clipping, which is at front row club level in my environment and they sing for hours on end without question.

A friend of mine, was a factory technician at Phase Linear and still has a shop in which he services and refurbishes the equipment. I consult with him periodically concerning the equipment. He actually has gone over all of my gear at one time or another. He assured me early on that the 700's would handle the Infinities without hesitation and he has proven to be correct. He knew this for sure because at the time that the QLS and RS 4.5's came out, they tested with them. He did caution me concerning the 700B, which I have never owned, as being less stable than the Series One and Series two. Clair Brothers used these exclusively for years for the concerts that they were contracted for. As a matter of fact, Bell Labs did as well for their testing and Audio Analyst in Montreal used them exclusively for the Summer and Winter olympics. They are very very solid power amplifiers.

In the 26 years I have never had a Phase Linear Power Amplifier fail at all and I have owned 16 of them.

Fun talk for me. I do not have many opportunities to talk about them.

Vito

P.S. I am always looking for more. They are easy to tuck under things such as sofas. Ha Ha

P.S. I have one of the Clair Brothers PA's, two of the Bell Lab PA's(only seven were made) and even a pre- production 700 that Bob Carver put together himself before they went into production. Fun stuff. No, I will not give out my address. Beware of the dog. Ha ha.

Hey Vito nice pic's...

Curious about your opinion of the base output of the RSIIA's compared to the RS4.5's with the watkins woofers. I notice that the 4.5's are susposed to get down to 24hz and the RSIIA's are rated at 25hz. I always wondered if the bullet woofers get as low?

Vitopanch

07-21-2006, 10:43 AM

Army,
Both my RS 4.5's and the RSIIA's are bi-amped with Phase Linear 700 power amps, and both use identical Acurus pre-amps, therefore I can give you an accurate answer.

Using say Power of Love by Celine Dion as a reference, which has astounding true bass, without question the RS 4.5's have much more bass impact. I would say that they both get down approximately the same hertz, but the RS 4.5's move noticeably more air. Sitting at approximately 15 feet from each pair and playing the same program material you can FEEL the air move past you with the RS 4.5's and much less so than the RSIIA's. Both produce tight bass at about the same hertz, but the sonic impact of the RS 4.5's is astounding whilst with the RSIIA's I would say that it is excellent.

I have never had the opportunity to do so, however, I would not be surprised that at equitable volume's the RS 2.5's would produce the same results. I could of course be completely wrong, however, it would not surprise me at all.

Vito - you are correct regarding the bass "punch" of the 2.5's. I have the RSIIb's and the 2.5's. The 12 inch Watkins puts out more bass feel. However, have you ever heard the 9.1 Series II's in the "video" mode? The bass is great then all of a sudden - with a really low bass signal - they impact almost like my SVS sub. Wow. Sold 'em though. :music:

Hi Vitopanch,
Great setup! Sounds like the Infinity's sound good with Phase linear amps?.. I was using two Threshold class A amplifiers with the Infinity's. I tried several amplifiers including 2 SAE 501's( I read they sound great with Infinity's) but the Thresholds seem to sound best.I've got the Infinity's in my garage until I rebuild the crossovers. I had to have the woofers rebuilt when I got them. I took them to local OC speaker to do the job. I am having problems with the bass though. The bass is deep but boomy (kinda like the thumping you hear from some cars on the road).The mids and highs are incredible! :yes: They belonged to my brother and I don't remember bass problems when he was using them. At first I thought I'd rewired it wrong as there is 4 wires per woofer, but I was careful and had made a good diagram. I tried the different amps, added an eq :no: and finally decided I'd put them up until I rebuild the crossovers. The crossovers seem abit complex compared to my DQ-10's I rebuilt. I think the Infinity's will be very nice when done.Do you use the external crossover that came with the 4.5'S?

As far as the pictures, are you saying that when you view them they are upside down?

Best regards,

Hail Vendo81,
First off with the pictures, before you upload them. right click on each one and select resize picture. The select the smallest size and it will work that way when you upload it.

Thanks for the comment on the setup. Yes, the Phase Linear's do justice to the RS 4.5's BIGTIME. I have some familiarity with the Threshold's and they are great power amplifiers. They will really make the RS 4.5's sing I betcha.

That is strange about the boominess from the woofers. I am quite ignorant electronically so I am clueless as to what will cause that. However, I can say this, that when operating properly there is zero boominess. It is amazingly tight. Good luck with that, I wish that I possessed knowledge to pass on.

Yes, I do use the active equalizer that came with the RS 4.5's. I have them activiely bi-amped using the box. Each Phase Linear 700 has one channel running the bass of one channel on one side and the highs and mids with the other side. As I was informed by a friend of mine who was/is a service tech at Phase Linear, they actually tested with RS 4.5's and RS 2.5's during their R&D and the marriage was in mind throughout the process. They get along real well, without any squabbling.

Congrats on having those RS 4.5's. There are not a ton of them around and IMO are visualy and sonically works of art.

I am quite interested in staying abreast of your progress as you get them going and matched up with your electronics.

Best regards,
Vito

Vito,
Thanks for the help with photos. I've been collecting audio stuff since I was a teen in the 70's. It makes since that the Infinity's were originally tested with Phase linear amps as the Infinity's need lots of power. The Phase linears are noted for LOTS of clean power.I've never heard Infinity with Phase linear but I've always loved the phase linear equipment. The looks can't be beat and my memories of "great" systems I remember from my younger days usually included a beefy Phase amp. I've been very tempted to buy a 400 off the internet. Just love those big VU meters! :thmbsp: I'll post the results when I get the 4.5's done.

Vito - However, have you ever heard the 9.1 Series II's in the "video" mode? The bass is great then all of a sudden - with a really low bass signal - they impact almost like my SVS sub. Wow. Sold 'em though. :music:

Well, the RS-II pic doesn't include the RS-1 drivers. In the picture shown, there are 4 SAE X-25 amps, an SAE 2401 amp, 3 SAE 2400 amps, plus assorted SAE tuners, preamps, equalizers, etc.

The RS-1 uses dual SAE A501s for the woofer towers and an A301 for the mid/high towers.

I kinda like SAE. :D

The RS-5 is with my SUMO collection. I like SUMO too.

I have a pair of RSII 's how do they they compare to the big brother RS-1a's

Well, I'm not very good at describing how speakers sound. Sometimes people describing speakers remind me of wine connoisseurs: "good finish, fruity with a hint of oak" and all that. Sorry, can't help you there, but here are my impressions:

The RS-I produces a broader souundstage than the II, with less directionality. You can wander around the room and the sound remains pretty much the same; you can even step between and behind the speakers, and the sound stays pretty constant.

The RS-I has a near infinite range of adjustments, between the active and the passive crossovers, so you can tweak them six ways from Sunday.

The RS-I has the ability to reproduce near-concert levels of sound. The low-end bass response dwarfs what the RS-II can put out.

On the flip side, I think the RS-I sounds more precise and clinical than the RS-II, particularly on things like strings. This makes it seem maybe a little "colder" than the RS-II. When I want to play something like string quartets, I'll go to the RS-II because I just like the warmer sound of them.

Overall, I love both sets of speakers. If I didn't have the RS-1s, I'd still be plenty satisfied with the RS-IIs.

Sorry I can't be more precise but I just lack the proper vocabulary.

I also have RSll's. I was curious, Phaedrus, which SAE were you powering your RSll's and how much power that is. Im ready to get into a power amp for mine rather than the Receivers ive been using with moderate satisfaction. Ive been jumping between my Mac 1700 and Marantz 2252b and while they sound nice they just dont have enough juice where i feel I can crank up the volume and not damage the drivers. If Phaedrus is not available, anyones suggestion would be greatly appreciated. By the way your setup looks like "heaven in a box". awesome!

phaedrus

11-17-2006, 07:44 AM

Mark,

At various times, I have used an X-15, a 2400, and an X-25 to power them (150, 200, and 250 watts, respectively). Aside from the fact that I'm a little partial to the X-series, I really didn't notice a lot of difference between the three. This is definitely a case of diminishing returns - I doubt there is any meaningful difference between 200 and 250 watts on these.

On the other hand, Infinity recommends amps in the range from 35-250 watts for them, and I think 35 is way too low. I think anything from 125 watts on up would probably be a good choice.

David

amped50

11-17-2006, 10:43 AM

The guy I bought them off of said they were real efficient and would run on a 40 watt amp. But I found out to really get into them a bigger power amp would be the ticket but wasnt certain how much power they would actually handle. Ill have to look into both SAE and Acurus, Jygesq, since you seem to be happy with them. Ive heard SAE with PA systems and they always sound impressive, real warm with a nice high end sparkle to them. But heard they were'nt good road amps,not happy getting bounced around in a truck. Cant have everything,right. Maybe ill post a pic when I find a good mate for my Infinitys. Thanks guys!

I got tiired of refoaming the poly-woofers and mids, and replacing the fuses for the EMITS, soooooooo...

~1999, scrapped all the OEM drivers and replaced them with much "beefier" 10" er's (DVC 300 watt rms attitudes) and some better midrange 4"... plus I dropped in an EAS100th Panasonic leaf tweeter (since the emits burned up)..

I also scrapped the crappy caps from Mexico and replaced the ferrite core inductors in the xover... had to reinforce the particle board joints since the new woofers blew out the seams... but it was worth all the work... they now are my 2nd system in the HT.....

Im curious, Auplater, how many Watts does your Wok put out? Of course that question has already arised, Right? For certain you have one of a kind RSll's. Thats surely a curiosity what they sound like.

Mark

Looks to be 1 KW...it's a sizzler for sure...:yes:

Actually, the improvements were substantial. Replacing the poly mids with Kicker resolution mids made a big improvement in clarity...then after the umteenth woofer refoam... the woofers went for other duty and the new ones were installed. <<-- much tighter bass with vastly improved power handling (better for ht) :banana:

cabinet reinforcement was a necessity b4 the driver swaps... Infinity wasn't the best at cabinet assembly... these things always resonated and buzzed, especially the solid oak wings... not sure why they didn't use more reinforcement on those... my set dates to 1979.... maybe why they went on to RS IIB's without the offset cab

Putting poly caps in the xover seemed to improve the imaging and swapping out the lousy trimmers fixed ongoing noise and intermittancy problems.

All in all, a worthwhile upgrade for sure... assuming one wants to get additional life out of the cabs and isn't looking to "investment" continuity for "original" legacy infinities.

Auplater, was Les Paul from the Far East"I did not know that!" Just having fun. Anyhow I thought about my RSll's future when the supply of infinity drivers go dry. Plus could I really improve the drivers and with what? I thought about the old standard upgrade to JBL . The bottom tens, now are they identical with the bottom ten, and just filtered for very low subsonics. When I first got mine I thought it wasnt working till a program with sub organ type bass was passed thru and saw it vibrating. Then I knew it could'nt be from the top bass driver because they dont share the same enclosure they are seperate from one another. You say ,improved power handling on the mids. How much power is that? I ask that because mine were popping when I drove to much bass thru them, but was from low powered receivers mind you. Then I ran my Yamaha PA power amp thru them and everything cleaned up and handled the bass very well. I thought about changing the crossovers to the mids to a higher crossover point to filter out excessive bass till I figured out they needed a cleaner power amp. Was this your experience too before you did the change over. Anyone else experience this with the RS's? Thanx in Advance!
Mark

auplater

11-25-2006, 01:09 PM

Problem with the midranges wasn't power handling... the rubber surrounds embrittled and split... and better cone mids also improved the clarity and imaging.

Power handling on the woofers made a big difference... I could drive them with either my nak 730 (150wpc @4 ohms) or my Adcom 555 II (~350wpc @ 4ohms) after the new drivers and they'd only complain at levels way beyond what the stock woofers would do.

Never bottomed out the mids... they just weren't as fast as the replacements... and the leaf tweeter was quite an improvement over the emits.

Regarding the QLS. Is that the only placement they have been in? They look too close to the back wall and too close together for good sound. Just basing this on my Q2's, which like to be much farther away from the walls. Something to try if it hasn't already been done.

Man, those QLS's look like a real macho speaker don't they? Big utilitarian looking brutes. I'm still looking :yes:

That is the only position, because that is the only place they can be seated. More in front, then you can't enter the room no more. More appart, then you can't open the door no more.

And they are pretty good, no boomy or something. Suprisingly, my IRS1.5 are way more critical for that mather.

They only miss in the midhigh, for what I suspect the domes. But well, they look nice idd :) Definitly in a big room I can imagine, but I don't like their sound at the moment...

Tuner: B760 from ReVox: still mine, but he could use it because his tuner was away for cosmetical repairing.

Amplifier: B250 from ReVox. Now he has 2, I gave him my spare B250 for a symbolical ammount. Also the rare B200 timer unit (costs doubel of the amp normally, but found the amp+timer for the price normally the amps goes).

CDplayer: B226 from ReVox. He found that himself ;D

And then 2 casdecks, 1 H1 and 1 B215S, both ReVox and identical devices but different fronts. The H1 he bought to do me a favour, because I was in need for cash to finance another buy.

Yeah, I'm too good for this world. Not even mentioning what I gave my dad and my little brothers. And all that from a 19years old Student with no money :)

Hi there.. i'm own a reference 50 and hook up with sony str-dg910 receiver
but the bass is not good enough to satisfy me.
and i'm not sure which one is problem the speaker or my new receiver.

Specs from the Infinity website:
Frequency Response: 44Hz - 40kHz (+/-2.5dB)
Crossover Frequency(ies): 300Hz, 4kHz
Sensitivity: 90dB (2.8V/1 meter)
Nominal Impedance: 6 ohms
Power Handling: RMS 25 -150 watts
Woofer: 20.3cm IMG
Midrange Driver: 12.7cm IMG
Tweeter: EMIT-R

Lack of bass could result from several things. First, these speakers are only rated down to 44 Hz, so they are not going to make prodigious amounts of deep, wall-shaking bass. They should, however, make enough bass to sound full. If you're looking for head-pounding, wake-up-the-neighbors bass, you need a separate subwoofer or much bigger (and much more expensive) speakers....and a BIG amp to drive them.

Here's a couple of questions and a couple of things you can try:

1) Are the woofer surrounds (i.e. the suspension at the edges of the cones) in good condition? If not, the sound may be muddy, flabby, or buzzy with diminshed output. The surrounds should be replaced if they are cracked, broken, damaged or just plain gone.
2) Are the woofers putting out any sound at all? If not, they could be damaged.
3) Make sure the speakers are wired in phase (i.e. positive wires go to positive terminals, negative wires go to negative terminals).
4) Your receiver is an HT rig, correct? I assume since you're lacking bass that you are not using a subwoofer. You might check your receiver's set-up to see if it is currently set up for a subwoofer, in which case it might be routing some of the bass output to a subwoofer that isn't there.
5) To reinforce the bass that the speakers are producing, place them closer to the wall behind them, but not so close that the bass starts to get boomy or muddy. You'll want to play with placement to get the best sound without overdoing it.

Hope that helps a little, and welcome to AK!

Well well, if think for the time being I have completed my assembly of Infinity speakers to meet all my needs. I started with a pair of RS 7 Kappa's that I have had since the mid 80's as my primary speakers. These are great speakers and have been driven by an assortment of amplifiers from Carver to Brytson's, Onkyo's and finally a Threshold 400A. I have always used a Carver C1 pre-amp. (no jokes please).

I have been planning now for the last 18 months my home theater for my basement project and have been judiciously acquireing gear as deals became available.

I now have a great set of Renaissance 90's from AGon which will be the main speakers in the HT setup.
I have been able to find a pair and a single RS 6 Kappa to be the center and rear speakers for the HT. All from Ebay, but the pair was particularily sweet as the vendor had them listed incorrectly and they went for a steal. Perfect shape with the stands. The single Kappa 6 cost me more than the pair!:tears:

As all of you have experienced Infinities love current and so I have bought all Threshold amplification to drive these. The Ren's are driven with a Threshold S/500 II - 250 watts/ch 8ohm 500@4ohms rated. Modest current ratings of 20amps/ch peak. I have had this amp upgraded significantly a couple of months ago and the peak current was measured a little over 50 amps/ch.

The Kappas 6 will be driven by 2 Threshold S/300 II which are currently awaiting rebuild as well. (While the 6's won't require as much current comparably to the Rens, the rebuilt 300's should be able to peak around 30 amps/ch.

I have preliminarily tested the setup using the pre-out from an Onkyo HT reciever I have in my cabana. Pretty good would be an understatement. The voicing of the Kappas 6 makes a pretty good fit with the Rens.

I will post pics at a latter time

Great room system:
Infinity RS 7 Kappas
Threshold 400A amplifier
Carver C1 pre
Harmon Kardon Tuner
Oracle Delphi 2 turn-table
$27 no-name DVD player :scratch2:(sounds great don't laugh)

HT system so far
Mains - Infinity Ren 90's - Threshold S/500 II
Rears - Infinity RS Kappa 6 - Threshold S/300 II
Center - Infinity RS Kappa 6 - Threshold S/300 II

JP completely rebuilt these Quantum 2's, and I ended up buying them.

I love 'em!

That was sometime back. Now, I'm just barely hanging onto my Infinity aficionado credentials with my RSbs out on near permanent loan and just my ES-1s on hand and they weren't even built at Infinity.

Those speakers do look a lot better in your room than they did mine, sound better too. That's a nice picture, but I think that those really need a pair of their little brothers nearby. :thmbsp:

As an experiment one quiet Saturday, try reversing the positions of your woofer and mid-tweeter columns, meaning move the woofers to the inside and the mid-tweets to the outside.

I have a set of Betas, which are similar in concept. I found that they need at least 10' between the mid-tweeter columns in order to throw a soundstage. The woofer placement isn't nearly as critical.

Just a suggestion, and I'd be interested to hear if anyone else has similar experience with Infinity 4-column systems.

I am replying 18 months after-the-fact, but I tried this last night, and it seems to be opening things up. I think I was hampering the system by putting the treble towers too close.

:yes:

I want to thank you for letting me know about these and contacting the seller. I owe you!

They have a few small chips in the veneer and a small tear in the grill cloth of one of the rear emits. The drivers look great, and the back panels for the pots and binding posts are in excellent condition. I'll get these hooked up this weekend and give them a listen.

Got the Quantum 3's hooked up tonight and put on a CD. The sound was dull. An ear to the front EMIT's on the right speaker revealed no sound. Checked the back EMIT - nothing. Same story with the left speaker - all EMIT's dead. Decided to fiddle with the tweeter pot, so with an ear to the rear EMIT I turned the knob slowly to max. No sound. Twisted the knob rapidly back and forth a few times, and noticed a tiny bit of static at one point. After some additional working of the control had continuous sound from the rear EMIT on the right speaker. A quick check of the front EMIT's determined that they too were working. Over to the left speaker, and soon had all EMIT's on that speaker working. With all drivers now functional the sound is pure vintage Infinity QLS! They sound incredible.

Sounds like your pots need some attention.... Pretty straight forward fix, and after you clean them up your emits will sound even better! Highly recommended maintenance by the resident experts here.... :thmbsp:

Bah, as I told you, I owed you (and feel that I still do).

Those definitely do look in very nice condition. It's rare to see the drivers look as they do with neither broken midrange tinsels nor pushed in dust caps. Shame about the veneer chips, but that's bound to happen with heavier speakers. You'll definitely want to disassemble those potentiometers as the center contact plate for the wiper tends to corrode badly that moving it as you did is only a temporary measure. If they're too far gone, I have at least one spare (and a parts unit) floating around here, somewhere, already cleaned up and ready to be installed that I can send your way (technically already yours anyways).

Say, are my eyes playing tricks or did you move your sofa quite a bit farther back than where it was before? Has that helped the sound?

Now, if only I can find a pair of very ratty QLS-1s to fix up...

Since yesterday I now already have a molested Infinity RSa in my collection. The wood has been painted white, the woofer's surround is gone, the grill is gone BUT it had a good EMIT. That was why I bought it, removed the EMIT, opened it, removed all the dust and stuff, put it back together and it measures :D

My Infinity Reference Standard 1.5's will be happy with a good tweeter again :)

Btw: how rude. Those IRSa's look better on the inside then its big brother. Is it: 'the more expensive the crappier the X-over looks?' ;D

But well, I have a spare woofer and a spare cabinet. Maybe it will come in handy once, now they just are in the garage (that might be a bit too moisty but well...).

Best regards,
Me

Glad to see you still have an eye for the Q1 JP. I was wondering if you had moved on in your speaker adventures.

I suppose that I have moved on in some ways, but I still have great respect for the big Infinities and would love to have a pair or pairs on hand for a secondary system, home theater, or the like where they'd find regular use. Of course, I'd prefer to have an example of the IRS series (IRS V, Betas, Epsilons, etc) and those could even become my mains in such a case. Yet, I've been wanting a pair of QLS-1s for enough years and seen too many locally be parted out by the wrong owners that I would very much like to save a pair and enjoy them in the aforementioned circumstances. Odd as it might sound, I'd rather find a beat up pair to restore than a pristine set as I quite enjoyed the restoration process and knowing I'm saving some from being destroyed for parts.

That's an optical illusion. Don't know how I managed to make my sofa look like it's halfway into the dining room. :scratch2:

I'm new here, so here goes.

I've got a pair of Reference Six's hooked up to a Marantz 2325 receiver, w/ Monster cable. I love the tight sound, the vocals and the mid bass driver really kicks in on live recordings. I've heard pricier speakers in audio showrooms but nothing below $2000 really outperforms them IMO.

Many, many years ago I heard the Infinity 1001A's in an audio shop playing an Eagles LP and I was sold right on the spot on the Infinity sound. Can't seem to find any data on the 1001's but it may have had a rear facing tweeter. Wish I had picked a few other Infinity's along the way but I always had a space problem in my living quarters. Love their vintage products.
