well, this post is quite late to the game. I have experience with stuart chapmans speakers.
I have a pair of what appear to be "prototype" t9 mkii's. they are 2 ohm speakers, and they are absolutely beautiful. They are 22" wide unlike the recent versions (16") they do it all. I have the first sunfire theatre grand processor and an old tfm25 carver amp.
very tight and dynamic, at any volume. even with my modest setup the speakers shine. plenty of beautiful sound for my 25 by 35 listening room.
