I agree, if I can fix this problem with some tweaking, I would prefer that to shelling out some more cash, as I am a broke grad student. I think the settings on the sub are OK, however the speakers are rather close to the wall (they are both in corners, about 1ft from the back wall and 1ft from the side wall. I will move them out a bit and see if it offers any improvements. I will also check out the Merlins that you mentioned.
thanks
