Helo..me and my buddy just got done making a new Tempest sub. I already have one and he wanted one as well. We hooked it up in his room, and it seems to sensitive. If we watch a dvd, it seems like the sub is almost always rumbling a little. It booms during explosions, but is parts when you dont think the sub should be doing anything it sometimes rumbles just a bit to notice. It can be a bit ditracting. We adjusted the level on the sub amp, but to make any real difference we have to turn the level almost all the way down! what gives?
