Hi Don! And Welcome!
IF your room is not too large(my old room was 13X28 and the M3s worked great)then the M3s are an excellent choice!
I also used another M3 as center channel, as dispersion wasen't a concern, and scans and pans were flawless!
In my current system in a larger room I'm still using the M3s, but now as rear surrounds where they work very well indeed in this capacity.
......I'm still using an M3 as center, but have added the M3s bigger brother: The M50s; for mains.
Were I still in the smaller room, ALL of my speakers would have been M3s!!
