The ESL-63's are excellent, i can say too that hearing Roy's for those few days i was working on them changed my view. Making a point source from concentric rings of radiation delays was made a light go on in my head. I had home made ESS speakers in the same room and i kept going back and forth with a sense of befuddlement how much the kind of radiation matters haha.I couldn't do what they did but about 15 years later a comment Don made at a Synaudcon meeting made another light go on.
A conical horn is a portion of a spherical expansion or point source and the acoustic properties of that shape as a horn were also such that the horn itself had in effect various "high pass" ranges depending on frequency and location in the horn. A conical horn with one driver at the apex is band limited so far as efficiency but one could drive the horn where it WAS active lower in frequency where it was correct, that lead to the Unity horn and then the Synergy horn.
We do make smaller versions for recording and monitoring studio's, the model in the picture (at a studio in England) have been used for mixing a number of albums so far with good results.
