ADS Speakers

Matching? You mean in like home theater?

I think consensus here is that similarly voiced speakers from the same manufacturer do best in multiples. But then I got rid of my sub and surrounds, so don't listen to me.

Yeah, I mean like mixing and matching! I guess if I was into the full blown "Home Theater Experience", then having an "HT Surround Speaker System" (ie; all the same design) makes sense, but I listen to 60% music so I'm more into the "Multi-Channel Stereo" effect.

I find that the Kef's and the DCM's actually compliment each other pretty well. The Kef's have the mid-range and high end clarity that supplements the roll-off up high of the DCM's. The DCM's obviously have the imaging and staging that the Kef's can't touch, so together they are more then their parts.

I'm thinking the clarity from 1Khz up to 20Khz of the Kef's will actually work pretty well set up as a pair for the center channel. Then use the ADS's which have a little more Bass extension to them for the surrounds.

I just don't want to lose any of that mid to high range clarity and I'm hoping they have a similar warmth within the mid-range as well.

I guess we'll find out tonight. I'll A/B the ADS with the Kef's and let ya know! :thmbsp:

How old are the L1290 speakers, it seems as though they can be had for from 200 to 500 dollars? Wonder how much they were new.
I recently picked up a very nice pair of black L1290's for $200. I got lucky and in my naivety offered $200 in lieu of the $300 asking price. Didn't know how good they sounded until I bought them. I'd gladly pay at least $300 for another set.
 
The larger ADS speakers DO like a lot of clean power. I've used an Adcom GFA 555 (200wpc) on my L1290s..and they loved all it could put out!
 
The poor little Kef's...

...they didn't stand a chance! Well, I need to be careful, because it's like bringing a gun to a knife fight. And to answer the question right off the bat, yeah, I bought 'em! And man am I glad I did!

All I can say is the ADS L730's are BIG, big in stature, big in sound, yeah, just plain big. As you can see in my image below they kinda dwarf the 103.2's and did I mention they are BIG?

Ok, to the demo! What do the Kef's have going for them? They are a little tighter and more defined in the bottom end. They don't go near as low (60Hz), so you precieve more depth to the ADS, but the bass is not as tight. Not sloppy mind you, but just not as defined.

Also the Kef's shine in what they are meant for, mid-range monitoring. They have a deeper more defined mid-range. I picked up on the touch of thinness that others have mentioned out of the 1 1/2" L730 Mid. Now don't get me wrong, the ADS put out a mighty fine mid, just not as detailed or deep as the Kef's.

Now here's where the L730's begin to take over; the high end! Both speakers traverse the end end like nobodies business. Clear, clean, crisp... detail galore! But the ADS are just a little more forward, and I like it!

And yes, some may call it bright, but I wouldn't go that far. I think it's the crispness and detail that folks mistake for brightness, or maybe it is the touch of forward bias in the high end. But the bottomline is the ADS owns the high end and the Kef's just reproduce it!

Now here's where the apples to oranges comes in, I don't think I would classify the L730 as a bookshelf or even a monitor. Ok, maybe not a near field monitor. More like a "session room monitor". Whereas the Kef's are definitely a near field or "mixing monitor". Like I said, not really fair to compare.

The other thing is the Kef's are a two-way and the ADS is a three-way, so the dynamics of the ADS can be controlled and optimized a little better. And yes, the 730's are definitely a little more dynamic! I believe this is why they sing the way they do up high. I haven't looked at the spec's but it would be interesting to compare the cross over points for the tweeters.

The one thing that did stand out to me is how close the ADS sound is to the Kef Sound. I will say right now that Kef's and ADS go together like peanut butter and jelly, like Hershey Almond Kisses... almost like they were meant to be. Could be the dome tweeters, could be the crossover designs, I have no clue, but the English Sound from the Kef's sure does work well with the Neo-German Boston Sound!

The demo I did had the speakers on the floor and really wasn't that optimal a system, but then and there I could tell that the ADS and the Kef's sounded just so much the same. Great stuff here folks, I kid you not!

Once I had them home I was able to hoist the L730's up onto some 24" Sanus stands I had for the Kef's and this REALLY made them sing. I'm going to write another post about my overall system at this point, but the best I can say is my room just took a major step up tonight. Best $250 I ever spent! Count me in as an ADS fan! And of course a Kef fan! :thmbsp:

The art of the ROOM!

I mentioned above about mixing and matching speakers to create an effect. And no disrespect to Vinylhunter, but I could sense that perhaps he was questioning some of my judgement. And that's what is cool about an Audio forum and one like the Karma. We all can respect each other's viewpoints!

I know we're all different in what our rooms look like, how big they are, how they handle certain sizes or configuration of speakers. I know many are on the quest for the perfect "full range" speaker pairs to reproduce the full spectrum of sonic and soundstaging magic from a true two channel source. I'm sure those speakers are out there, and I applude those on that quest!

However, I for one have always thought that you could perhaps reproduce that magic, not in a single box like the 1590's or 2030's, but by strategically interfacing multiple speakers to create a fabric. So let it be known, here and now, that yes, SimplySound is a multi-channel audiophile and thank god for Audyssy (yes, heresy, I know)!

Now what is interesting about tonight's little interlude into "Audio Improvement" is how it came about. When I first purchased my Kef's about a month ago, I thought they were the greatest "monitor" speakers I had ever heard. They complimented the soundstage imaging of my DCM Timeframes pretty well by bolstering the middle to high end. And that they did very well.

However, with the layout of my room, I was still hearing separation of the Kef's from the fabric of the DCM's. In other words, the Kef's were sounding like boxes removed from the mains.

This is when I started to get the idea that perhaps I needed some larger surrounds that had more spatial imaging so they could tie better into the fabric of my TF700's.

With the L730's I hit that mark on the head! Maybe it is the larger cab, maybe it is the fact that they are a three way, but the 730's just linked in with the DCM's seamlessly. And all of this without doing any Audyssy setup!

Like I said above, the room took a major leap forward tonight! And what I'm really intriqued with now is using the Kef's as a WTTW configuration center speaker.

Right now I just have one of them hooked up off my AVR. I yanked a B&W CMC out of the mix and man, that single Kef put that B&W to shame. I think this just reinforces what I have heard about ANY center channel speaker being a compromise to an LCR or better yet, a quality two way!

If you look at the images of my room below, you can sense where I'm headed. I have a pair of Kef's 107's ready for pickup in the middle of April. I'm thinking a front wall with the 107's being augmented with the 103.2's up high and the 730's in the wings.

I'm thinking this may end up being sonic nirvana with the 107's able to cover the full range down to 20hz and the rest of the speakers, doing their part to augment each and every element they are good at!

Yes, I know that if one isn't carefull, this can become a muddle of mud! But I also think it could end up being a fine example of the fact that what you can accomplish with a single full range, you can also accomplish with a fabric.

All I know is it's going to be an interesting trip from here to there. Heck, it's already been an interesting trip from there to here! I'll let you know how this strange trip ends up! :thmbsp:

I hear ya!!!

I just snagged a Belles 400 on Ebay that I'm going to dedicate to the Kef 107's when I get them. This means the Yamaha M85 will be relegated to second fiddle doing surround duties on the L730's.

Uhmmmm... 30Watts Class A with 265 waiting in the wings in Class A/B! Yeah, I'm thinking it's gonna work out well! :yes:

Wow, just wrote a writeup on the CAL Icon MKii I just bought. It really smoothed out the high end of the ADS's... guess it goes to show, you want good audio, go to the source!

Just stumbled upon this. Not sure if anyone knows anything about these folks, but I have never delt with them and do not have any association with them. I provide this purely for informational purposes!

"The Robot Underground (November 5, 2004): All a/d/s (aka Braun) speaker repair can be done by my good friend Rom So at ads_speakers@yahoo.com.

Rom was an outsourced recone specialist and a loudspeaker R&D engineer for ADST for over 12 years. He has virtually all the original a/d/s parts for both old and new drivers that carried the a/d/s brand name. He's from Cambodia and still has trouble with lots of questions online so I'm starting to take over for him when dealing with the public and sales.. Leaving him to just build repair speakers.

For the record, quite a bit of that is inaccurate now, and some of it was inaccurate then.

Congressman Issa sold DEI prior to becoming a member of Congress, and was not running the company at the time DEI acquired ADST though he was a board member and minority shareholder.

DEI never officially designated Richard (Rom to his friends) as a service center, but unofficially many people looking for parts or repair services were referred to him particularly on out of production systems.

Richard certainly has been and continues to be THE go-to for parts and service expertise on a/d/s/ and ADS systems.

DEI still provides support for a/d/s/ customers where possible, primarily with manual or other documentation requests.

FWIW, I bought a new pair of Braun L710 (later re-badged ADS) ~1973. I also listened to the L810 and found them to bee a tad too heavy in the bass region.

They were one of the better sets of speakers I owned. I replaced them with the oroginal DCM Time Windows in 1978.
 
I waiting on receiving a pair of L400s, my first experience with ADS. I have the similarly sized 3-way Braun L300s which will be very tough to beat. I am anxious to see how the 2-way compare. The Brauns have ascended up my speaker chain leaving the Dyn A-35s KLH FIVEs, KEF 103.2 presently in the dust. B&W 805s remain as my best monitors but the L300s are really not too far behind. The ADS L400 definitely wins over in the looks department though.

As I lust over B&W (in general; I lust over well-redarded brands I don't own and have never heard/auditioned) I'm superglad to hear that speakers I own are hitting in the same game as a highly-rated brand as B&W. There are, sadly, just too many fricking good speakers to own every one that makes sense, financially and in terms of space considerations. The ones I own (L420, L400) are bass monsters for their size and beautiful examples of German technology translated by east coast audio standards. If I had room I would own every model in the line, considering they are getting more and more scarce as time goes on. Someone should pony up and resurrect the brand as a viable modern business model. I would LOVE to see some modern-day high tech versions of A/D/S or Braun speakers; I would guess that they would sell as well as any modern speakers, and one certainly can never have enough of a good thing.:D

German technology? I think of Braun speakers as New England technology (dome tweeters and acoustic suspension) translated into German. Anyway, all that's really important is how they sound.
 
Uhmmmm... 30Watts Class A with 265 waiting in the wings in Class A/B! Yeah, I'm thinking it's gonna work out well! :yes:

Got the Belles 400 Amp hooked up to my front mains (DCM's) today. Sounds a little smoother and cleaner than the Yamaha M85. I think it is 200wpc and it doesn't have quite the punch of the 265wpc Yammie, but definitely a little more detailed with a wider sound stage and better instrument separation. Very subtle, but you can tell!

Then I hooked the Yammie up to the L730's. Now that was an improvement as well. Broadened the soundstage imaging on them, so now they tie in even better with the DCM's up front. Better bass definition and the M85 provides quite the mid-range punch for the ADS's. Columbo is right that the ADS's will handle all the power you can feed them!

Haven't run the Audyssy on the new setup yet, but the room just keeps getting "a little better all the time"... :yes:

I travelled 600 miles round trip for a pair of "usable" 1290's for $300 bucks. Absolutely the BEST money I've ever spent on audio. Period, hands down, without a doubt! Mains in living room right now. They replaced Platinum Audio 3's and Ohm Walsh 4's. Never, ever sell em!

Reposted without permission from classicspeakerpages.net but with the specific intention of preserving this history within AudioKarma! For this I hope I am forgiven!

From Bob Hazelwood

"Perhaps I can shed a little light on your whatever happened to a/d/s/ curiosity. I was employed by a/d/s on two occasions. The first from 1983 - 1993, then from 1996 - 1999, so was in a position to see some of the changes that resulted in the eventual downfall of a/d/s/ as a popular audio brand.
a/d/s/ founder, Dr. Godehard Guenther, is a brilliant man who was always a little ahead of the market when it came to product ideas. in the late 70's through early '80's a/d/s/ speaker sales were doing startlingly well in both home and automotive categories, but Godehard felt that people would begin to appreciate the benefits of purchasing complete, high quality integrated system solutions. This was quite common in Godehard's native Germany, but in the US we had a mix and match mentality. This thinking resulted in a/d/s/ purchasing the Braun electronics division from then owner, Gillette. The plan was the Braun Atelier electronics were to become a/d/s/ Atelier. This turned out to be an extremely ambitious project because the plans were in place for the complete electronics line, but only a few of the new models were fully developed at the time. The additional personnel and costs to tool and develop the line were phenomenal. The development of many of the products, such as the flagship R4 receiver would be simple today but extremely difficult back then. In the late 80's the building-blocks didn't exist to make a computerized digital receiver with full system control and multi-room capability like we take for granted today. Now there are chips for virtually everything, but a/d/s/ needed to develop everything from scratch. While speaker sales were still going strong, and the automotive division was doing great under the leadership of industry leaders John Bishop and John Caldwell, the costs of this expansion into home electronics were taking their toll.
The M and CM series speakers designed by Dana Hathaway, were introduced at this time also. They represented a departure from the original a/d/s/ sound but were quite good and arguably were objectively "better" in all technical aspects. They continued to be extremely well reviewed, but since the lion's share of the marketing resources were directed towards Atelier the M-series didn't get the same focus as the earlier products, so they aren't as well known today. Just after this, a/d/s/ became involved with a start-up company that had a great concept called Frox. The Frox products were the forerunners of today's Media Center PC's, foreshadowing all of the media integration and home automation we now take for granted. The difficulty was that this system was envisioned when PC's had 286 processors and 512K of RAM, so this was also not a simple project. We have quad-core processors and multiple gigs of RAM to do that today. The plan was for a/d/s/ to provide the powered 5.1 speaker systems that connected digitally to the Frox controller through optical cable. The a/d/s/ speakers actually got built, but the Frox systems never got off the ground due to software and technical difficulties, resulting in disaster for the company. So a/d/s/ ended up stuck with a lot of unsellable inventory, and took a further financial hit. I'm skipping quite a bit, because there were some other plans and projects that didn't go as expected, such as the worlds first expandable 6-zone multi-room multi-source whole-house system controller with LCD control pads (in 1986!). All these things played a part watering down the company's ability to market their products effectively. Eventually, a/d/s/ sold Braun Electronics back to Gillette, and cleaned up after the other projects, but the damage was done. This all led to a need for a capital influx which led to a merger with Museatex from Canada, and the formation of ADS Technologies (ADST) as the holding company that had a/d/s/ and Museatex as their brands. In this era the company was run by Kurien Jacob, an audiophile and turnaround specialist who orchestrated the merger. Kurien integrated the Museatex and a/d/s/ operations. a/d/s/ benefitted by the addition of a superb audio engineer, Ed Meitner, to the group. a/d/s/ introduced some interesting and good performing products during this era, but with the exception of a few car speaker products none achieved the market traction of the earlier home speakers. Over the next few years, ADST acquired autosound manufacturers Orion, and Precision Power (PPI) along with ribbon speaker maker Apogee Acoustics. The a/d/s and Apogee factories were combined in Wilmington, MA, and later moved in with with Orion (and later PPI) into a new purpose-built facility in Tempe Arizona. I left soon after this to join Cambridge SoundWorks, so don't know much more about what went on inside the walls. I do know that at this time, the autosound side of the business was outperforming everything else, so the folks running the business apparently focused their efforts in that direction. The unfortunate fallout of this was that many of the excellent home products from a/d/s/, Apogee, and Museatex are no more. Ultimately, as has been mentioned elsewhere, ADST was purchased by Directed Electronics. At least to my eyes, it would appear that Directed doesn't seem to have much interest in continuing a/d/s/ as a high-technology value-added brand. It looks like a few of the holdover products may still exist, but the newer products carrying the brand logo appear to be generic turn-key products with nothing special to offer.
Godehard Guenther, on the other hand is still making some cool, innovative products under the Soundmatters brand. Although a different focus than the original a/d/s/, some of the Soundmatters products (especially the subwoofers) show some clearly different thinking that is definitely a Godehard Guenther trademark.

Additional Repost. I would hope Tom & Co would approve...

Bob, that was an excellent and lengthy addition to this post. It is great to have someone who was part of ADS to add to these comments. I do have a question for you: who actually did the design work at ADS on the L1590, L1290 and L1090 series (and other variants) that were introduced in the mid-1980s? These speakers, even to this day, are excellent designs and among the better products ever designed by ADS.

Also, I believe that the company used the ADS trademark until the M-series was introduced, and then a change was made to a/d/s/. I incorrectly listed the L1590 as an a/d/s/ version; it should have been ADS L1590.

--Tom Tyson


Mike Kelly was the VP in charge of product design at the time, so he would be the ultimate decision maker, but I believe Dick Moore was also heavily involved. This was just before I joined, so I'm not sure exactly what the exact contributions of the various team members were, but Dick's initials were on most of the documentation. Dave Marshall (also now with Ariel) was the mechanical designer. The industrial design was from Braun Design in Germany. One interesting tidbit is that the cabinets were manufactured by a German furniture company named Hados, and sent here for installation of the ADS made drivers. This is a complete reversal of the typical loudspeaker company practice of building ones own cabinets and stuffing them with drivers built elsewhere.

Need Help on ADS Speaker ID

Hey folks, just scored a sweet pair of ADS mini bookshelf speakers at a yard sale. They sound fantastic!! Have been scouring this site and the Web, in general, but can't get the model #. Pictures are attached. The back plate says 4 Ohms and 'Made in Germany.' Dimensions are 9.75"(H), 5.75"(W), 7"(D). Seems like a 5" woofer and 1 or 1.25" tweeter. They are wood with a metal front grill. They are amazingly heavy, maybe 3 pounds heavier than the L310AWs that I have. Any help appreciated. Cheers.

Wow! What the heck are those? The a/d/s logo makes me think they're later US-made ADS speakers but they clearly say "Made in Germany." Did the later a/d/s company go back to Braun for some of their speakers? The cabinets and grills look different from my L300 and L400 speakers. Does anyone know what these are?
