ESS speakers "Translinear" Transstatic

ESS memories. In the 70's, I had a pair of the AMT 4's, the Heil unit was about 1/2 the size of the AMT 1's. I thought they were great, but I sold them and moved on to Kef 104ab's. About two years ago, I got a pair of the AMT monitors(the foam surrounds were all shot). I always felt it didn't make sense to pair the heil with a 12" driver so I paired the 6" heil with a 6" Peerless mid/bass in a new cabinet (sized for the proper Q). I also have a subwoofer using a pair of the Kef B139's crossed over at 100hz. The sound still stuns me.

I purchased my ESS AMT Monitors in 1982. I used them in a large room with thick carpeting, absorbent ceiling panels and curtains on three side from ceiling to floor. I listened to them with a powerful SAE amplifier usually running pretty much flat out. There were no room reflections or standing waves. The sound was extraordinary in that the the ambience in the recording (if any) was faithfully reproduced. For twenty years I never heard anything to beat this system. When I played "The living Daylights" LP then my *neighbours* spoke of the realism of the train (Note brick houses 65m apart).

The woofers have had surrounds replaced twice and the diaphrams in the EMT units have been replaced once. Another set of replacement surrounds and diaphrams are on order.

They are now being used as rear speakers with two Tannoy D900 speakers in front and Musical Fidelity amplification. People still jump to answer the phone when a DVD soundtrack rings in the background.

I have just taken delivery of a stack of equipment to biamp the Tannoys, and if that works well then I might do the ESS Monitors as well. This will allow me to streighten out the response curve a bit and match the back and front speakers better.

I have pair of ESS speakers Monitor Series 4 in very good condition.What do you guys think how much should I sell them for??
Thanks

i have heard kithara loudspeakers they sounds good
i want to make a clone
is there somebody who know what woofer model they use?

Sunnyjim,interesting stuff.I have some Crown ES212s which use similar RTR made stat panels.The Crowns use 12 5inch stat panels arranged in a curved screen 3 high by 4 wide.The bass [below 350hz] is handled by two ten inch woofers in a sealed box.Even by todays standards they sound superb.They are clearly better than the older Quads and many of the Martin Logans I have heard.They are surprisingly dynamic and have real world loudness capabilities.Apparently they cost the same as a family sedan in the mid 70s so they should be good.
