My M60s replaced some older 12" DCM "boom-tizz" speakers and at first I also thought the bass of the Axioms was lacking. However, with a sub I can go FAR beyond the bass of those two 12" drivers. Usually I don't want that much bass so it is irrelevant. The quality of the bass in the Axioms is far superior to that of the bigger speakers, but those larger cabinets do provide more boom. I think you'll notice with the M60s that you can discern individual drum beats and bass notes with far more clarity than the big box speakers.
