The ESL-63's i am familiar with, in fact they had an impact on me at a time when i was making flat and curved electrostatic drivers. My Boss at Intersonics has 63's and asked me to "fix" them which meant by passing the protective spark gaps.
I said ok but cautioned that ALL of the ESS drivers i made eventually died sparking death in the quest of higher output (also his complaint and some months later so did his).
Having them home i listened to them in front of my home made ESS speakers and was struck by one unexpected aspect of their "sound".
At times it sounded like the origin of the sound was behind the panel and my conclusion was it was the effect of radiating much of the sound from a single point who's radius put the origin behind the rings of radiators caused by the delay network.
That radiation from a single point in time and space, creating the the radiation or as you say Launch of a single simple acoustic source and confined to a specific angle was the upshot of the original Unity horn and then the current Synergy horns.
I don't know how good an explanation it is but i was asked to explain that horn and some other stuff on the fly a while back. The "Expansion rate" video here goes into that.
Anyway, thanks for your kind words.
