Find some Pics fellas, I'm left handed. Even mechanical drawings or sketched out on a grocery bag and take a Pic. :-)
I always like DQ and DQ-10s are on my bucket list for sure. So are a few of the ET panel designs.

BTW here is the old VMPS web site address. The first 3 pics.

1984 guys... Mr Bass himself Brian Cheney of VMPS. I would love to bring back the 3 models I listed and 2 sizes of Bass columns, servo and non-servo.
I have a system that is pretty good direct coupled to 12K class ds. Well controlled bass system for the money.. 20-700hz flat as an arrow, by changing 2 of the 12 driver in the SATs. I'll hunt up some pics.. The short stack in on my Virtual Page.
I use First Watts Active OB XO it has a 40hz step baffle of 3, 6 or +12db (?)..

1980-90 tech, they had a passive system to cut YOUR mains at 80, 100 up to 250 for PANNEL speakers at the time. WAY ahead of their time. THEN they enclosed the slot on the bottom. (A little history)
VMPS Bass system
The Passive Radiator (PR) located in the bottom of the cabinet already has a certain amount of mass attached to the center, by the factory. By adding or subtracting mass from the PR, it is possible to make system tonal balance warmer (higher Q) or tighter (lower Q). This is accomplished by changing an inert mass such as Mortite rope putty, the substance attached to the PR. You can buy additional putty at most hardware stores but your speaker is delivered over-damped (a bit too much putty), so that in almost all cases, you will tune the speakers by removing mass from the PR. Mass is accessible by inserting your hand into the slot formed by the base and the bottom of the cabinet. Removing a very small amount, no more than 1gram of putty, will be sufficient to make the adjustment.
Moving mass of PR is very low. Since a PR is driven equally over its entire surface by the active woofer's backwave, the diaphragm will move pistonically even if it is not rigid. The PR cones are treated paper. Paper is fine as long as you don't have to listen to their high frequency noise and distortion products. Facing the PR down and slot-loading it out the front filters such products out nicely.
We invented the slot-loaded PR and decided not to patent it, since we would spend our life in court defending against copies. We knew we were on the right track when we saw a Klipsch monitor at the AES in 1984 with a slot-loaded PR.
Fun ay....

These were a ton of fun. I still have 2 pairs. It looks like this pair has a ribbon problem or two maybe.. They still make repair kits..
Infinity Infinitesimal RS 0.2 Speakers.

Speaking of Pass. I’ve heard these. I just wish I could hear a Rushmore. I heard some of his horns about 25 or 30 years ago. Huge speakers I’ll see if I can hunt up a pic or two.
|
Nelson Pass, I’ve heard these speakers and 2 or 3 slightly different versions.
Single concentric drivers every time. I love horns.
Now if mozartfan would pay just a little attention he might see something interesting for a dual purpose single chassis driver and a well designed horn. 7 watts with a 101 sensitivity is incredibly loud..
If you looked up through the throat they weren't matched very well at the flange connections. We matching the ports on ours. That top "U" had highland sheep wool. The best sounding was rough coat the last 18" or so of the outlet. I ran mine with MC240 Macs. Just about 30 watts to much. I wish I would have had a MC225 at the time. That would have been the ticket.. :-)
Not according to Mr Pass though. :-)
He was designing Threshold at the time I think.. It was a while back.. Sure supported his products through the years. See him just popup in a Pass talk group..

These are my RMx Elixirs after sound coat was added a few years back we were seeing if it made any difference with a HDF cabinet.. There is a rear fire section now and one of the neo 8 is in the rear position and a AC 8" ribbon is put in its place in the front. Dual Mono Pole.
There is a 1.5 BB Isolation plate with pods and a Stainless wrap along with a 30lb polished stainless cap. Almost 500lbs just for the monitors. I don't use the bass section. I'm thinking of pulling the drivers, blanking the openings and adding 50lbs of activated charcoal per cabinet. They are one of a kind now for sure. There were only 16 pairs ever made and under 6 in the US. 9 total left.. 2 sets of 3 are part of the 9 sets. James B. Trunural processor with Ampzilla amps..
FUN speakers. I'm not kidding 10-500 watts.. 92 sensitivity. I know they have seen 1000 watts. Never an issue. Mine are 13 years old.. They will last another 50 years.

I did have a pair of A14, I just couldn't swing the A19.

I'll tell you where I lived as a kid, the biggest brand in the Bay Area was Infinity and Klipsch. Martin Logan was for the rich and famous and B&W was around lets say. VMPS was very popular, almost cult like and JBL was everywhere. A lot of music makers used JBL in their homes and there were a LOT of music makers in the Bay Area.. Every rancher I knew had JBL, Mac or Marantz valve gear..

I’ve heard them with Pass equipment. I kept staring at them. I expected Dr. Who to pop up.. They sure disappeared in a room. Jean-Luc Ponty was on the menu. I remember that I brought it.. The guy had isobaric subs made from 1" thick clear plastic. Quit a sight and sound. The drivers had the biggest motors I had ever seen, they must have weigh 50 pounds each. I’ll see If I can fin a pic.
Side Note:
HAY Crazy SUBS pics are cool. I like all the DIY stuff.
I’d give my eye teeth, If I had eye teeth for the ESS Transar ATD, that were all custom. MAN they look good, I know they sound good..

decooney, I'm with you I'm enjoying the pics myself. Memory lane the old shows and show room with all the neat speakers. Your right, ALL gone. BUT we got AG, AY!!
Merry Christmas, keep um coming.. Wonderful stuff, better than eatin' bugs..
Regards

AR 3A wonderful speakers.. I never had to work on many AR speakers because they seldom screwed up. I sure like. I seen a few on stands too, that was the ticket. I used QSO 808 with a ring mid driver. I'm actually listening to them right now. Very close in sound. Look at the bass drivers and the cabinets. I don't think these were a matched pair.. ????
|
I new a guy named Mugs he had a pair of these. They sounded better than the QLS1. Theses were powered by infinity amps and used an Infinity preamp too. No Idea who actually made them.. They were in one of the first large treated rooms, I had ever heard and the guy had 2 (TWO) VMPS passive subs. He worked at the largest record retailer in the Bay Area for 10 years.. 10,000 records at least.. You wanted to hear it, he had it.. :-) Mugs went to heaven. :-)

VMPS STIIa/R. This pic is in the 80s. Look at the cables and cable risers.
|
I actually have the First Watt OXO and the 15" drivers they recommend. I was going to go with a neo 8 or 10 planar and a AC ribbon and enclose the back on the planars.. 2 months later the company that made the metal work kits went out of business. I shelved the project.

I sure have enjoyed it. I don't want to leave any names out either!!!
EVERYONE thanks for the great contribution to the thread. I gotta dig up some DIY pics and an unfinished project or two or three. LOL
Merry Christmas EVERYONE and happy gift give away.

Thanks decooney I'll clean mine up..
|
decooney, I wonder what those Bohemoths weigh? Mercy I like um!! I know they sounded good, probably still do. :-)
|
This Snell gave me an idea to try. Is the rear lower driver active or passive? Does anyone know? I have never used or heard them..
Regards

There you go Master M.
Tannoy are some wonderfully designed speakers. I love the cabinet design on a few of their models. They didn't cheap out on quite a few. Master cabinet makers blush at some of the custom Tannoys.. Stunning cabinet and finish work. Not to mention they image like a razor if you want, and super low distortion. The crossover works too. There is a lot of TECH in Tannoy.

decooney, what are the 3 round gizmos below the third driver on the front baffle?
You got all kinds of goodies..
