Alan is right. I own M22's for my HT setup and the detail is superb. I have an STF-3 from HSU for a sub and it fills in for the lack of bass in the M22's.

I also have a pair of M3's in my family room for 2ch music and they are great, but they dont have the detail that the M22's do. I did run "Return of the Jedi" thru the M3's in the fam room and they are still pretty impressive though.

M22's are better for HT than the M3's IMO.
