Dave,
I'm in Connecticut too, less than an hour away from you, near Danbury. As luck would have it, I presently have both M60s and M22s hooked up. I'm running the M22s as dual center channels with the M60s as mains and QS4 surrounds. I have a DIY sub as well.
For what it's worth, I wouldn't run either the M22s or the M60s without a sub, especially for LFE in movies.
I see that you've already placed your order for the M60s. But if you're still agonizing over the decision, I'm extending an invitation to come and listen to my speakers and compare them side by side. My room is similar in size to yours (15x20)
I was really happy with the M22s as my main speakers for the past couple of years. I just came across a really good deal on the M60s that I couldn't pass up.
PM me if you want to set something up.
Joe
