I can vouch for the M3. It’s no slouch at all. It’s quite spectacular. I’m very impressed with their performance so far in my master bedroom playing from a modest receiver. I also have a pair of m60ti in a larger space and really like those too.
Having listened to M3 now for a few sessions I’m already scheming how to incorporate a pair of m2 into my office space and a pair of m3/m5 on walls in my garage.
Short version: I love the clarity of axiom speakers and detailed sound. I’ll bet a pair of m1 or m2 powered computer speakers with a small sub ( if desired ) would be very good.
Have you compared the M3v4 with your M60ti?
