The reason I am considering the M22 and the M50's is that I am going to be putting this into a small section of an open concept living/dining room. As such, I will be at most 6-8 feet away from the TV, and I will only have maybe 7 feet between the speakers.

From what I have read, it seems the M60's need a lot of space to have a good soundstage, and I don't think I have the space.
