I made a point of visiting this room after the session, and was similarly impressed. The speaker ($6800/pair, no model number in the printed literature that I could find) uses two 12" powered (370W) woofers, and an 8" full-range driver with an Alnico magnet. The drivers are all mounted in an open-baffle (dipole) configuration. The soundstage presented by the Live Audio speakers was quite spacious, without the specificity of imaging within the soundstage that you get with unipolar speakers, but very listenable. Here's the picture of the speaker with designer Sylvain Turcotte.
