Quoting Morris Schæffer (view post)
Actually we do have a 5.1 set-up. There's a subwoofer underneath the TV, and two speakers behind the seats.
I know it's not the best set-up, but it's the best we can do with the location of the TV, and the number (and location) of power outlets in the basement.
Plus, we're moving in a year, so there's no point in re-wiring everything now. It'll be great in the new house.
