Yeah Mo, a few years ago there was some discussion here about the M3 having no crossover on its midwoofer and just rolling it off "naturally". The 2000 SoundStage review comments briefly on it, for example. The Axiom data lists an M3 "x-over" at 2.2 KHz, but unless the design has been changed, that presumably would refer to just a high-pass filter on the tweeter at that frequency. That feature apparently isn't on any of the other Axioms.

Enjoy the music, not the equipment.
