You wil really fill up that 300sq.ft. with sound with the M60s. They have a much fuller sound than the pin point accuracy of the M22s. I've had both and the M60s feel warmer less clinical in there presentation and they have lots more potential for bass output than the M22s. The vocals are more pronounced on the M22s than on the M60s which was hard for me to accept when I had the M60s in house and compared the 2. I ended up going to the M80s, they are a good approximation of the M22/M60 combination. I even ran the M22s with the M60s, now that was an awesome setup, even a little better than the M80s, IMO.
