I second what grunt just said.

22s will work for just about eveerythig unless you want some more bass, then you either need to add a sub or get the M60s. If you want to watch movies and really feel the LFE, then you will need a subwoofer regardless of what speaker you get. I find a dedicated center makes dialogue a little easier to hear as you can adjust the center channel volume up a little more than the mains.
