The blurb doesn't mention that he's used the Quad ESL-63 approach to make a synthetic aperture line source, which is to say it should have an ideal line source dipole radiation pattern at all frequencies. In essence, it emulates a vertical line, whereas the ESL-63 emulates a point source, with a spherical radiation pattern. This overcomes a major ESL bugaboo, their tendency to beam in the highs.
I've long wondered when someone would make a line source that way!
Still to be determined, how well the dipole woofers blend . . .

Hi Josh, I thought Acoustat tried something similar with the a narrowing dispersion patten in their Spectra series? However a quick Google search only picked up a very few vague reference's, what do you think?
S.P.E.C.T.R.A. - not the evil organization in James Bond films, but what they called Symmetric Pair Electrically Curved TRAnsducer.Rather than running all of the panel area full range, they were logically split in half. One half ran full range while the next set ran midrange and bass and the remaining area is bass only.

That is similar to Jazzman's segmented stat design, but the center was full range and then as you radiated out to the edges the highs were attenuated out and then the mids until only the "bass" was left at the outside edges.
There was no "tweeters in" or "tweeters out" on either speaker.

The German Audio Exklusiv makes line source ESL similar to the concept of the Quad ESL-63. They even had some models with high voltage tube amplifiers. https://www.audio-exklusiv.de/classic-line/95/elektrostaten-p61/
Interesting, I didn't know that.
