Anyone hear the new Consonance M15 speaker yet?

It's an interesting design in that it uses a horn-loaded tweeter with a crossover at 500Hz to a 15" woofer. Frequency range is purported to be 30Hz~20kHz and sensitivity = 98db. I'm not sure if it is yet available in the States? Here's the link to the product:

I'm considering making a change from low sensitivity planar speakers with high powered amps to high sensitivity speakers (horns or otherwise) with low wattage SET and this speaker may hold some promise? I'm a little concerned with noise (ground loop and otherwise) moving from a balanced system to single-ended. I had some problems with ground loop noise in this room prior to going balanced, so any thoughts and suggestions would be very much appreciated. I have a video projector in the system which certainly makes groundloops more difficult to eliminate.

It seems to me that 500Hz to 20kHz is a very wide range for a tweeter? If they can pull it off, that's certainly a good thing.

Thanks!!
