@Tetsuo: I got the same speakers, too. These 5.1 speakers kick ass. And when i got mine for 55, and free shipping, it was a bargain.
Just put the sub on the floor by your feet. And im damned sure your not getting the most out of your sorround with your left and right front speakers right next to eachother. And whered the center speaker go off to?
EDIT:
This is how this system is supposed to be used:
(NOT 56k FRIENDLY, so dont bitch.)
Subwoofer is on the floor, front and center in place, and the 2 rear are, I'd say about 5 feet behind me.
Dont ask about various room decorations, arent mine. Like the sunflower mouse pad, isn't it awesome though? ;D
