I have the bookshelf M22 and the on-wall M22. The on-wall M22 does require a sub-woofer, whereas the bookshelf M22's will play bass sufficiently without one, except for the deepest bass. (As long as you don't buy a cheap receiver. I originally bought a $200 Sony from Newegg and it didn't have enough power to supply any bass.)
