Prof - I know very little about this topic, only what was 'leaked' by an insider and not denied by another.
But, as I said, the approach harkens back to the very beginning, before we settled on dynamic drivers in an enclosure; and it attends to our shared first-principles of point-source, freely radiating energy without close range diffractive interference. And as I recall (from about 1974) our reasons for rejection were based less on technical appeal than on costs to market such a radical approach . . .
Sidebar: At our first 1977 CES, we twenty-somethings showed our model 01 and 02 and a static 03 prototype, and offered an unheard-of 10 year warranty - all to much interest. I remember being teased by an industry somebody that being from Kentucky, weren't we supposed to be barefoot and pregnant and sipping moonshine . . . ? Cognitive dissonance. Imagine if we had showed up with seriously radical products beyond our active equalizer.
Since this is all water long under the bridge, I invite anyone to comment that might know more than I about this mythical omnidirectional project.
