I am hoping to hear them at some point. I don't even know if they are in stores, because AT seems to work mainly through installers. I don't live very far from AT's headquarters, so maybe I'll give them a call and see if they'll let me into their sound room for a listen. You know I'm always ready and wiling to listen to something new.
The review describes the new bass loading technique, which looks like a modified transmission line. What's particularly exciting is that they seem to be able to get bass down to 30 with power out of a relatively small box with no loss in efficiency.
In search of the Holy Grail.
