ESS speakers "Translinear" Transstatic

Good data nexusstudio. I visit this thread every time someone posts new comments.

I would love to hear one of these today and see how reality fares, when compared to my rosy memories.

I was the factory representative for this line in 1971, and took these speakers around to audio dealers for demo. I believe that the electrostatic element was at that time, manufactured by RTR, the same company that made the elements for the Crown ESL (Elkhart Indiana), and the original Infinity Systems Servo-Static. You are correct about the oval driver being built by KEF. This woofer was totally flat in appearance, and behind it was a long labyrinth, forming a complex transmission line network within the cabinet. It was precisely tuned to be in near perfect phase with the front (output) of the KEF woofer. I remember the sound of the very deep bass, passing thorough walls of the sound room and into my office, while I was speaking to customers on the phone. This design was indeed way ahead of it's time, and delivered remarkable sound, especially considering it's relatively small size. As far as being as good as electrostatics of today, I think that the Maggie, Quad and Soundlab all have better mid and top than the ESS. As far as bass, my memory is probably blurred, but I would guess the ESS to be better than the Quad, but certainly not equal to the output of the Soundlabs.

Sean, you are right about the memories, it was pleasant thinking about the ESS again. Your question about Soundlab, all the large speakers in the line have excellent bass, and are exclusively electrostatic. The mylar driver has very low excursion, but is ultra fast and phase accurate. For what it lacks in deflection, it makes up by radiating area (in excess of 15 square feet). Properly set up, you are assured to get the "oomph" you describe. Electrostatic bass still "sounds" different from a traditional piston woofer, a music session with your favorite software should determine if it has the sound you like.

Trelja, no, we lost the ESS line about that time, and instead picked up the more popular JBL commercial line and Infinity Systems. I had a hell of a time learning all the technical materials and specification sheets required for JBL. I quoted parts and power requirements for commercial sound applications such as auditorium reinforcement and rock band equipment. It is nice though, to have owned and lived with so many technologies, it does however make me even more committed to my Soundlabs, which I consider to have the fewest compromises.
