Axiom Home Page Forums General Discussion Home Theater 4 speaker surround with pre-existing M3's

The difference between the M2/M22/M60 and M3/M40/M50 families is not really that big. They're certainly not "incompatible" or anything.

The big question, I think, is whether you are likely to end up using one pair of speakers as "mains" and the other pair wired in parallel as "center" speaker in a 5.1 system in the future. That's the only case where matching between the speakers is a real issue, so that sounds don't change in timbre as they move across the soundstage.

Somewhere on this forum I posted my notes from direct comparisons between M2, M3 and M60. Other than the amount of bass, the differences were much less than I had expected.

Bottom line is that for your intended use it doesn't matter too much, and you should base your decision at least partly on any future plans you might have.
