My room is about 12x15. I have sony tower speakers(ss-u251), polk cs1 center channel, boston cr57b surround, ps111bk sub, denon avr788 receiver, ps3 and my tv is the samsung ln32a550.

Being that my room is pretty small, I decided on the small little sub assuming that it would give me enough boom for my smaller room. Don't get me wrong, the sound quality on the little sucker is amazing, but the "umphh" factor isn't there even for my smaller room. Is there anyway to tweak it to give me more bass?
