Also, keep in mind that a bigger speaker will not be "too much" for a small room.
A bigger speaker will mean more range and a "fuller sound" but will able to be played at louder levels without distortion (hence the term "enough to fill the room").
In that case, the M60's would give a fuller sound down to the mid and upper bass regions than the M22's will. However, the M22's will fit the job very well. I have them and couldn't be happier, but in my situation it is impossible to have floorstanders so I don't have "upgraditis"
.
Good luck!
