I originally went with the M50's as a replacement for Paradigm Monitor 7's. Thought the M50's were definately superior. I then purchased a pair of M80's as my mains and am using the M50's as surrounds now (overkill).
A friend of mine has M22's and M60's, I think your right on with the 50's being a little deeper on the bass. Maybe not as accurate on vocals with the dual 6.5 vs the 5.25's. Anyways, its a great speaker if you prefer a floorstander over a bookshelf.
Love the M80's though, IMO i find them better than the M60's.
