Acoustat Electrostatic spearkers


I’m from old school, I still have and always will use these speakers. I have 2+2s now. I just pick up a set of model 6s which have two interfaces on each speaker. My question is can I just run speaker cable to the other from that to the power amp. Or should I run two speakers cable one to each interface. Or use a set of shot gun speaker cables.

@bdp24 That does not sound like it would be all that hard to come up with something. People have done that successfully for the Sound Lab.
I sold them, it wasn't until much later that a few guys figured out how to make the OTLs stable
Uh yeah- that would be me... FWIW (one of Atma-Sphere's claim to fame was the first reliable OTL).


Sure- just don't exceed the phase margin of the amplifier when you design the feedback loop (this is really all that was about, and it really shouldn't have been me that solved this, as its standard control theory which has been around for a very long time, and this rule applies to any tube amp or traditional transistor amp!). That was the Achilles heel of many OTLs. The designer(s) tried to get greedy in an effort to send the output impedance down, but the price for that wasn't worthwhile. However, OTLs don't need feedback to drive the Acoustats quite nicely! A good friend Frank (RIP) had a set and I heard them many times.
