Axiom Home Page Forums General Discussion Home Theater 5.1 to 7.1 speakers

Tone-wise I imagine M2 or M22 would be a better match for the M22s you have. If you are going to be listening to "5 channel stereo" (ie fronts and backs get the same signal" then M22s would probably be best if you want to be able to crank up the volume... but I think most people here would recommend something like PLII or Neo6 rather than 5 channel stereo.

If you're not doing loud 5 channel stereo (which is really just having a second set of mains) then M2s should be fine.

I don't know enough to comment on the distance but it doesn't seem like very much. I have seen suggestions that you do 6.1 with a single QS8 on the back wall in these situations but not sure that is the right answer for you.
