Hello autoboy
I don't think the M60s are full range speakers. I agree with the recommendation that you go with a pair of M3s and a nice subwoofer.
I agree with Chess. I had a pair of M22s and have a pair of M2s and to my ears they sound thin.
Why this is I dunno. I have a bunch of Michaura M55s which have the same 5.25" drivers as the M2/M22 but use the 3/4" titanium tweeter which was used in the Merak line and the old M2tis. The Michauras sound spectacular ... especially after a bit of surgery ... Mills resistors, fuse out, and Jensen paper/oil caps.
Anyway, I think the M3s are superb for 2.1 channel music or as front speakers in an HT system in a modest size room.
