As an M60 owner, I can tell you for sure that placement can make a huge difference in how they sound. Axioms have been described as "accurate" repeatedly on this forum. Another aspect of accuracy (other than the accurate sound) is that they seem to produce a very focused sound pattern. If you turn one of them a couple of degrees and then stand back about 15 feet, you can really tell how the sound field coming from that speaker has moved. I think this has to do with the fact that the aluminum drivers aren't as susceptible to warping, twisting, or unusual flexing when they move like cones made out of less rigid materials might be. Hence, they always "shoot straight". In order to get a good stereo image, the speakers need to be in the "correct" postion relative to where you sit. This is so that they can get all of the sound waves to hit your ears at the right time from the right direction.
You certainly do not have a lot of room to play around with speaker position in your current room setup. The M22s might be a better choice. They, in combination with a sub will do the job just fine. They will also give you more placement options due to their smaller size.
If you rarely sit in the same listening position, then go for the 60s. They will sound great. Speakers will only "image" correctly for a relatively small area. Once you move out of it, you lose the image. If you are playing pool, or sitting off center in the HT you won't be near where the image is. It wouldn't matter which ones you have.
Bottom line, if you want good sound AND a better chance at proper stereo imaging, get the M22s.
If you just want good sound, either will work.
