Sonus Faber Electa Amator 2 Arguably the best speaker I’ve ever owned. Isobaric design, perfect highs, mids and deep bass, never bloating. Made all music sound just as it should. Played them on a Naim 250/252 system with Nordost Frey cables Sold them after I dismantled my entire system some years ago.

.................................... AR-2Ax, my first decent speakers while in college. Got em with wedding gift money. Anyone remember the AR sound booth at Grand Central Station, NYC? Sam Goodys?
I was ransacked once, I still miss them, but I inherited the Fisher President II with the Electrovoice Drivers I still use.

I own a set of the DQ10's. Picked them up for $375 from the local retirement center about 3 years ago. Mint! 1 owner, all original except for a refoam. They still amaze me when I put something on that I haven't heard in years...70's-80's era stuff that I'm very familiar with..Hear things I'd never heard. And especially 60's-70's Jazz titles. |
When Jim Winey brought out Magnepan speakers it made most of these electrostatic and hybrids obsolete. This is because that, while being more accurate than cones and boxes alone, they are shrill and cause listening fatigue after a short time. They are also prone to blowing out--try an early Phase Linear on them at any volume--and they are expensive and difficult to repair (I did it in my shop--not easy). For contrast, my 1975 Tympani I-C speakers sound just as good today as they did when new, and I have NEVER had any issues with them at all no matter HOW LOUDLY or softly I play them with very good electronics, which are required for accurate speakers. They were fun when new, and certainly helped lead the way to Maggies, but they did not make the long haul. If I am not mistaken, Magnepan is still in business and innovating every year. Try them IN YOUR ROOM and see for yourself. Cheers! |

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 (?).. Regards |
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. Fun ay.... |
*energy 22 pro monitor - the most musical speaker i'd heard up to that point [1986]. *AR "Magic Speaker" - uncanny representation of recorded space - "you were there." snell type A revised - the most magisterial speaker i'd heard next to the- *IMF studio monitor - the first transmission line speaker i'd heard, it had an utter ease about it and a bass like granite. *celestion sl600- nothing threw a stereo image like those babies, with a surprisingly wide sweet spot. magical.

Have a pair of 5jr's from Habitat...30?ish $ for undamaged black cabs and screens. Just needed some typical tlc on the drivers, a good wipe-down on the cabs.... Sometimes one should step back as one proceeds onward, as there is what deserves a 2nd Listen. It reminds you of Why. ;)

@jasonbourne52 $1390 in 1977 is $6224 in today's dollars so it's no surprise at all. |
@ditusa i have a pair of DD-5500 inside the pool house, along with some Talon Pheonix and Duntech Princess.

Got my DQ 10’s in the mid-70’s and kept them playing for forty+ years. Got them for maybe $800 a pair back then. Finally gave them to a friend a couple of years ago when I replaced them with Magico A3’s. To me they have a similar sound that made them listenable to my DQ 10 immersed ears. But what I really wanted back in the seventies and couldn’t afford were Quad ESL 57 electrostatics, whose appearance Dahlquist cloned. I joined the Army late 1977 after the Viet Nam War ended and was able to shop at the U.S. Army Audio-Visual stores in Germany. There you could get real bargains on great higher end equipment. Much to my chagrin they had a pair of the ESL 57’s on sale for only $400 (a month’s pay), but I had the new Dahlquist’s, so let the Quad’s pass through my fingers. I might have purchased one of the newer Quads instead of the Magicos were it not for the fact they are manufactured in China.nowadays.
