Heh Heh! If you want to hear M80s, Tharkun is your man. The crazy son of a gun has 5 of them, plus 2 QS8s in a 7.1 configuration. OOPS! I forgot. It's actually a 7.2 configuration. The ".2" is TWO EP600 SUBWOOFERS! He's in Tracy, CA. and, in all probability, those two EP600s will be solely responsible for the next quake in the S.F. area.
He is a good guy. If you PM, or email, him with a request for a listen, I suspect he'd be happy to accommodate you.
