I got a chance to hear some of these the other day. The concept is electrostatics to cover the mids and highs with an integrated woofer(s) to provide the bass impact that the stats don't have. Pretty successful, I thought. There was a bit of that disconnected feeling you get with a poorly integrated sub, but not much, and I wonder if it could be simply dialed out (didn't notice if there was a volume control for the woofers, an assumption on my part). Everything above that somewhat hard break between the lows and the mids was very nice. A bit airy in the highs, probably just what I'm used to, but not sizzly at all. And the mids were just lovely - detailed without being etched, smooth coherent, very open and spacious...nice.
