Thanks for the informative links, Chesseroo. I didn't read anything about that phase switch, but I did read a lengthy argument about which sub sounds best. Seems like overkill to me. I can't even turn up the ep350 all the way. All I want it to do is accent my m60s for music and make some booms and rumbles for the occasional action film.
One more question...has anybody gone from 5.1 to 6.1 and found the added channel worth the added dough?
