Audyssey set the M22s at 120hz? That does sound strange, even my QS8s get set at 60-80hz by Audyssey. What did it set the rest of your speakers at?
The 3808 has had a number of Audyssey updates, possibly the program has a glitch in the 2808?
The M50s will sound much closer to the M3s you have, if you want a brutally clear midrange in a floorstander then you need to go with the M80s or even the M60s, which are not as crisp in the midrange but are still very clear, IMO.
Axiom has a tradein program you could utilize to get rid of the M22s.
