I have both M60s and M2s, and find their timbre to be very similar. At higher volumes you can definitely tell the difference, but at lower volumes with a subwoofer the two are surprisingly hard to tell apart. I also used the M2s as surrounds for a while (after getting the M60s but before getting QS8s) and found they worked very well, however the QS8s definitely gave a more "spacious" feel.

If the surrounds have to go near your listening position (a few feet) you might want to think about getting 2 QS8s rather than 4 M2s, unless gaming makes more use of 7.1 than movies do.

If you are looking for timbre matching I would either go with M60/M2 or M50/M3 rather than mixing M60/M3 or M50/M2.
