Do you have room in the back for a pair of M2's. I have heard in ceiling speakers and not to say their bad just different. Everyone has there own taste, if you can in wall then go with one of the Axiom in wall. To me I would keep the speakers the same. I say this because of the tweeter keep the tweeter the same it will just sound better. I ran a pair of Paradigm ADP-190's with my M22-VP-100 it sounded good, but when I replaced the ADP's with a pair of QS8's wow what a big difference. So just my 2cents stick with the same speaker. Thanks and have a good one and have fun with the new speakers.
