Interesting thoughts I've never considered my M3s as lower resolution or muddy. Compared to my M22 {a little more M2 compared to most other Axioms with double 5.5s} I guess that could be, in a total audiophile sense more accurate{sweeter highs}. Without a bass bump.

I was under the impression that the 6.5 in the M5 would add more dynamics or clarity over M22, with greater capability than a 5.5 inch driver.
