Hi dakkon,
In my dedicated Axiom Home Theatre room which is less than 2400 cubic feet. All the boundaries (floor, side and back walls and floor) are made of concrete with exposed surfaces made of drywall and carpet. Originally with two EP500 and two EP600 I could make the picture shake. It can't be the screen it is a painted type (Goo Systems). It might have been my eyes shaking in my skull . . .

Currently with four EP800 (thanks again Ian) I am experiencing a superior more satisfying bass performance at a lower volume level. Perfect bass for movies and music . . . heaven, I’m in heaven la, la, la, la . . .
