Yea, the M2 is nothing special on the bottom end. Not bad for the price IMO. The mids are classic Axiom though.

As others have pointed out, given that they roll off fairly steeply below the -3db point, even an 80Hz crossover would be low. From what I understand you need reasonable output below the crossover in order for the blending of the bass and the mid drivers to be smooth.
