In case anyone cares I just got a set of minimus 7's and minimus 77's and as these have a bit of a following I thought I would post the differences. the 77 are the larger of the two and have 4" woofer instead of the 3" on the 7. the tweets are the same. Construction is identical other then the woofer and cab. Both have a choke (surprising) and a cap XO. The 77 is rated at 55wpc the 7 at 40. I have not hook any of them up yet but did notice the 77 foam surrounds are going south, the rubber 7's of course are fine.

There's been sales lately of upgrades for the x-over for these on the auction site we all know and love, for around $14. Tentoze requested I do not post auction links unless I'm in the dollars and cents forum, but they should be easy enough to look up, my friend.

thanks for the info but i will not be upgrading these things, i have real speakers to work on :>) I just hooked them up and they sound OK, highs are a little harsh, mids pretty good, no bass as expected. The 77's do have more bass but the 7's sound a little better to me for some reason. I'm going to try the 7's with my Pioneer powered sub I have never really used.

these will make good speakers for me RV. :thmbsp:

The 7 has a 4" woofer, the 77 and similar X55av's have 5 1/4" woofers.

I have a pair of the Optimus Pro 7 AV (shielded woofer) and 2 1/2 pair (one orphan) of the larger Optimus Pro-X55AV's. The X55AV's have the same dome tweeter as the 7's and 77's, but have 5 1/4' shielded poly cone woofers.

I have also seen a variant with a horn type tweeter (88's?).

Here is a rebuild/upgrade project on the 77:

I think these are pretty close subs for the 77's and 55's

Thats better. Sub crossed at 90 or 140hz (at 60 there is a big hole). Nice sound, as to be expected it is a sat/sub sound but pretty good. Gives my unused Pioneer sub something to do. As it is not the best sub and these are not the best little speakers they make a good match. this sub with higher end speakers sounds flabby and bloated, with these sound pretty good, nice match. I'll find a use for it (my daughters room?).

both the 77's and 7's were made in Malaysia. 77's cat # 40-2054 / 7's cat # 40-2030C

What's a 4" woofer? That's like calling a chijuajua, a dog. They must be using the tweets as mids because tweets for those would have to be 1/8" micro-piezo with a .007 ufd crossover cap. and a lightbulb filament for a LP filter.

Heeeeeeheeeeee!!

I'd get some earmuff straps and use them for headphones. They'd be perfect for MP3's. :smoke:

Someone claimed (in print on a website) people who said the Minimus 7s didn't have enough bass didn't know any better. That they were the same people who are used to/fond of/under the assumption enhanced bass or "mega-bass" from the newer offerings is what good bass is all about. Oh brother! :lmao:

I may not be the foremost authority, nor have a golden ear, but geez, that's just too funny!

For the size, and what they are best for (in my opinion nearfield low level listening and as surround sound backs), they produce a nice bass "sound", but no real bass. The mind likes to fill in what's missing, to compensate for what's not there. The sound from my small subwoofer can be heard/felt from the front of the room while the minimus 7s round out the experience. but they ain't thumpin'...

I do like the 7s very much but boy, call 'em what they are!

We are in the process of painting and doing other things in the bedroom and had to move teh Sherwood 7650 and the 7s to the home office and left them on the desk. A couple of nights ago I plugged the set in as I had not been using the 7s but the Koss headphones for listening. Close up and personal and at low levels on classical they actually do very well. Was surprised. As I got further away I remembered how much I do not like speakers much smaller than a coffin. They are somewhat hard and grainy but the Sherwood has this failing so I may be hearing the receiver as much as the speaker short comings. The bass that is there is surprising considering the driver cone material. Wonder if the cone could be made more ridgid without adding mass which I suspect would help.

I have Minimus 7's as the surrounds in my home theater. They are excellent for that purpose.

Hey now, I have a pair in my office system, and can get loud and low enough to get kicked off of a military installation. I have cinder block walls and a little Technics 20W integrated amp/tuner/eq. A little respect for the Sevens.

Thumbs up for the little 7s! I use a Japanese walnut pair at work driven by a Pioneer SX-7730 for background music. For that purpose, they are great. :thmbsp:

A vote for 7's. It is one of the most flexible speakers around.

Just want to clarify- I love the 7s too (look at my signature- I'm hunting more). For the purposes most of us use them for, they are very good- nearfield listening, low to moderate level listening, desktop listening, bedroom listening, and surrounds. But for the same price many a still fairly small speaker with a 5 1/2" driver can be had, and it does make a big difference.

I've always had a fond spot for these little speakers, even though I long, long ago retired mine from active service.

The Minimus 7's were my first pair of dcent sounding speakers I purchased as a kid. Not very flat, but with a little help from an equalizer, they sounded quite nice.

I used to use them as surrounds early on also, but my video setup went way beyond that application about 10 years ago.

My home theater is all 7's. It is a 6.1 system and it is plenty loud for me! Of course I am not huge into home theater but this system works well in my small tv room.

Let's just say they are good speakers for there size. Solid as a brick, good components and design BUT they are about the size of your fist so they are only going to sound so good. Funny thing is I would never buy these unless I was looking for something super small because for the same price or less I can get KLH 23's which absolutely blow these out of the water. They are fun and will work well in the RV. I will say they do handle volume pretty well for their size.
