It's an attractive design, but it looks like the mid/tweeter beams (assuming that they're using the entire panel, rather than segmenting it with a crossover or time delay) and I wonder about mating an electrostatic tweeter to a dynamic midwoofer, particularly a ported, omnidirectional one. The designs I've heard that do that (admittedly, made some years ago) sound almost like two speakers -- a blurry dynamic one in the lower frequencies, and a clear electrostatic one in the highs. But, of course, that's just speculation, implementation counts for a lot.
