Hmmm. I really don't know how to ask this, but whenever I get about 3 feet away from my SVS I hear the truly deep gut-wrenching bass that everyone talks about (16-46 pci) but as soon as I sit on my couch (8 feet away) I can only hear it slightly, and all of that incredibly deep bass has completely disappeared. I have it calibrated, and have even tried different spots in my room (right now it's at the left-hand corner of my room). I was thinking of maybe turning it UPSIDE DOWN. That's right. I just want to see what will happen to the bass. Maybe I can improve the bass? I've already tried every location in my room, so this would be the next step. Would this hurt the SVS in any way? I certainly would not even dare try it if it's going to damage it.
