If you want bass, use a 24" Hartley in an appropriately designed box. Last one we built for Mark Levinson's HQD system was about 5' tall, 2' deep, and 3' wide made from 1.25" press board. It was on 4" casters as it weighed a few pounds, but if you power a pair of them right, you will get some bass in your room that your friends and neighbors will not have.
Cheers!
