Soundman, I have M22's and QS8's in my approx 12x20' living room setup (also have a HSU sub and planning on VP150) which is hardwood floor next to a 4'x10' picture window.
Bright is not a word I would use to describe it. Clean, clear, detailed are more accurate words to use. Everybody has different tastes, so an audition is probably the best, but go listen to some Klipsch and you will probably hear bright or shrill speakers...the M22's are much easier on the ears than those.
Good luck with your quest.
