As far as I know only the M3 (and maybe the M50) run without a crossover on the woofer. I vaguely remember a comment that the larger woofer happened to roll off at about the right frequency for that combination of drivers, and that the sound was better with a "no crossover" design than any of the other configurations that were tried. Couldn't find a reference though, so take it with a grain of salt.

Perversely enough, from the dozens of reviews on the M3 it probably comes across as the smoothest sounding of any of the Axiom speakers. If there was any hint of midrange resonance I have to think SOMEONE would have commented on it.

The rest of the Axiom line seems to run conventional crossover designs, presumably 12dB/8va but not sure.
