Kodiak, one of the things you might want to experiment with if you will place the 60s in a corner or close to wall boundaries is port plugs. Each M60 has three ports. Axiom has them available.

How you position speakers in a room and where you listen from has a lot to do with how much you will enjoy them. I was reminded of that again at my buddy's place last night. His floor-standing KEFs are very similar in sound to M3s but they sound like a $10 speaker from his seating location. When I had him sit 5 feet closer, it was a revelation.
