ESS speakers "Translinear" Transstatic

I just posted some comments as a former dealer for ESS. Whatever happened to the owners and can you tell us the inside story of what happened to ESS. My guess was that they went for the mass market and failed. I remembered two of the owners, Gary Hudson and Phil Coelho but not the third, who was a college professor.

I just came across this thread. I HAVE A PAIR of original ESS transmission line speakers; the ones that were made just before the Heil tweeter were added.
I purchased them in Toronto for $900 in 1970. I moved back
to NY in 1972 with the two speakers on the roof of my car. Going about 70 mph on the Thruway in the middle of the night they lifted off my roof rack, (I thought they were gone) and they did a perfect 180 degree flip (as seen from my rear view mirror) and landed on the side of road, sliding, with almost no damage. One of the speakers broke part of the top teak wooden panel, which I glued together again. Ten years later I replaced one of the Kef 9x12 oval speakers; the part cost me $125.00 in the 80's. My wife didn't like the size, and when one of the fuse housing broke I retired them to the attic. They are still there! and I think in good condition. I will post a photos when I set them up. I remember incredible sound playing Pink Floyd - Money.
What sold me on them originally was a cover shot of a stereo magazine with them competing with 10 foot Magnaplanars Monsters and coming in second.

Just found this thread, picked up a pair of m102's (1980 I believe)recently and am quite impressed with them. They are all original,only needed a good cleaning and a little touch up on some edges. Was able to get original grill cloth from
ESS. They are amaizing and play well on all music.

just bought me a used AMT 1D that was built after 2001 so it's the newer line but the cabinets are the same design. I will improve it some more with dakiom feedback stabilizers and the fact I have many sound processors like dbx, bbe, behringer, it will definitely have very little limitations cause I can alter the sound in which so many seem to have their limitations. I also acquired an AMT 10B, and with my ohm walsh 300 mk 2 rebuilt by ohm, at least i can switch. I also have eminent tech lft 8a's and a maggie 2.5r's with new ribbons, I have the best of both worlds and if i ever find space, i can always pull out my DINOSAUR, an ACOUSTAT SPECTRA 33 the electrostat the size of a room!

i could never tolerate the original ESS AMT1 in the top where it was so rough as to be intolerable. the same effect was present in early shibata equipped cartridges and the original threshold 400 amp. i can only imagine the high frequency cacophony if all three of those components had been used together.

i never got to hone in on the lows of the towers like transtatics with their transmission line loading in the lows. i will guess they werent quite as good as the IMF and Fried embodiment of that approach. i think mike wright of the UK did that design work on the IMFs and later TDL.

there are numerous speakers out there now with heil drivers including one with a very large amt (Atma Audio) marketed by Paul Squillo Music Systems.

i heard a LARGE version of this speaker at the moorpark theater while attending a performance of dan hicks and it didnt exhibit the roughness i referred to that i heard in the AMT1s.
perhaps this technology has evolved to a more usable state.
