I have m60s in the same sized room - sound is fine - most of time I have just 6 inches off the back wall - in terms of appearance, they did dominate the room a bit when they arrived and my girlfriend was not entirely happy - however she has come to appreciate fine sound. I would love to get the chance to hear how a sub + m22s would be in my room cos it would prob look a little neater but not sure when if ever that will happen. For the moment happy with m60s.
