Our upstairs neighbor complains all the time about our HTIB system. The short version of my question - if I move the subw to the front of the TV and place it on a slab of granite will that help with the bass sounds not going up to her place? I now have the subw between the rear projection TV and the wall and the back wall on a piece of foam. Any help for placement would be great. We may have to go to headphones but my wife does not want to do that and I don't really want to spend the $400 or so that 2 good pairs of wireless phone would be.
