Charles, on a serious note, I bought some little triangle thingies that go in the corner. I have a small room, and the corner treatments help to tame some of the bass boominess. Also helps deaden the echo in the room. Noticeable even when I make noise and talk.

Others have looked into room acoustics more than I have, and am sure they will chime in.
