Mac,
The correct solution is to treat your room, especially with bass traps. I
imagine you already know that. If you're on a tight budget there's still
plenty you can do. For example, plastic bags of fiberglass from the hardware
store stacked up in corners are effective if unsightly. Much more is in my
Acoustics FAQ:
