My home theater setup is located in a converted, carpeted bedroom that's about 14.5 x 12.5 feet. I have some placement constraints, such as the exit door, a closet door in one corner, windows, and a large radiator in another. I have two questions:

1. I have one 12" sub in the system, which provides more than enough bass, although there are some room modes (around 50 Hz) that keep the response uneven. I have an identical 12" sub that I could put into the room. Would this smooth out the bass response, given the relatively small size of the room? The current sub is located near (but not in) one of the front corners. The other one could go anywhere along the back wall (the listening chairs are a few feet into the room from the back wall.

2. Is this room too small to bother with 2 additional rear channels for 7.1 movies? The current monopole surrounds are located slightly behind the listening area along the side walls, which works fine for multichannel music and movies. I could put two timbre-matched surrounds directly behind the listening area, but they would be fairly close to the listeners' ears so they would have to be operated at a low level and with apppropriate delay.

Any suggestions would be appreciated.
