Well, just to round it off, there's SVS and the Axiom EP350. The general battle is between the Army of the HSU and the Stormtroopers of SVS. Can't go wrong with either. Budget concerns get you to the HSU STF-2.

You really should talk through the whole thing with the folks at HSU and SVS. Room size, what you want to maximize (low or loud, music or movies, etc) Really good folks at both places.

Just make sure you get a big honkin' unit that will keep you from being disappointed.
