Personally, I think the 5 1/4" midrange is part of the Axiom magic. I'm not nearly as fond of the 4" midrange in the QS4s, although mine are probably tis, not v2s, and certainly not of the current lineup. Of course, when I mentioned this to Ian, he kind of laughed and said it was more about the crossovers and matching the drivers to them than in the drivers themselves.

I think to match the M60s, you need the same size drivers, though.
