I live in a 3 bedroom apartment with 2 roommates who have yet to discover the wonders of home theater. One of them is a very lite sleeper who has interupted my movie watching quite often. He seems to mind a little bit less since I made one little, cheap tweak. That is, I put cut in half raquetballs underneath the sub. It really does reduce the rumbling in the room. These or maybe more expensive cones may help more than moving the sub. Also, putting a sub against a wall can add even more bass to a room.
