Also make sure that your DVD player is connected up right. When you were watching U-571, the display on the receiver should have said Dolby Digital or DTS. If it didn't, then something is hooked up wrong.
By the way on Mark's comment, no matter where I positioned the 600 in my space, it shook the whole house. I even positioned it on my landing at the bottom of the basement stairs and it was firing up towards the main level. It made no difference...it was/is an unstoppable force
. You have a larger space than me by about 2500 cubic feet, with a 500 and not a 600 so maybe you do need a corner for greatest thump. But then again Sirquack had a 500 and he has 2500 cubic feet more than you and he was happy.
