Silent Speaker from Direct Acoustics ???

Has anyone heard these speakers yet? Positive Feedback did a review on him
good post-I'm interested too. The guy behind them has a LONG solid track-record. Anyone??????
Certainly cheap enough, and it looks like some thought and care went into the design. But zero marketing [a good thing!] leaves one wondering. I'd love to hear them myself but I know of no owners nor of anyone who has heard them, or heard of them. Maybe some others here have some experience with them. Winslow Burhoe was a designer of some repute back in the day. [Anyone remember Burhoe "Blues"?] His site points to a review from 1995!
