I found the NRD interview, a little difficult at first, but then warmed up to the explanations. A lot of focus on bass response, and how controlled directivity ameliorates many bass problems. Hopefully NRD when he reviews the speakers, will focus on what they DO, as opposed to what they don't do, and let's talk about soundstaging, imaging, liveness, and yes, bass response.
I found myself listening to the whole thing, which for YouTube and shortened attention spans, says alot, and I DO walk away with a better understanding of the goal of OB and controlled directivity in the home environment, so thank you Clayton.
My former Dunlavy speakers were, I think, designed with the anechoic chamber in mind, where the designer was less concerned about the room since he probably figured there was no control over that, so tried to perfect the square wave reproduction or whatever. Regardless of the goal, OB speakers, to my ear(s), just sound more like live, real music, and that's what it's all about.
