"Are you, per chance, referring to Peter Walker's Quad ESL-63's????"
Yes, my old boss asked me to "fix" his (removing the spark gaps which protected the speaker). I had built electrostatic speakers before so he asked me to try. I had never seen a speaker like that though (concentric rings) and that was (a dozen or more years later) the inspiration for the full range Unity and then Synergy horns (some of which are in the videos).
Here, instead of rings of full range sources, the hf, then mid, then lows are produced sequentially within the horn, at dimensions appropriate for the frequency range such that the sum appears to been from a single driver.
Best,
Tom
