If the room is the thing, how do I fix this?

I am moving to a new place. It would be nice to have a golden ration room, 10 X 16 X 26, but it isn't happening at this time. The only room I have is either in the living room with all sorts of stuff around, including a television, or a 10 X 11 room. I think it is going to be the 10 X 11 room with an 8 foot ceiling.

What can I do to improve the acoustics of a small room?
