After seeing the specs on the woofer in the M100, it was pretty clear it would make for a nice, 32 Hz subwoofer.

Somewhere on the Axiom site, there is a pic of an EP-100 using this driver (just one) in a compact sub ... so an M100 has three, which is basically the same as a 12 mm X-max, 11 inch subwoofer tuned to the mid 30's.

Should have some pretty good wallop.

Speaking of wallop ... the EP800 is looking like something to try out, just for fun. There is SO much to subwoofers besides "how loud is it at 20 Hz".

The old EP-500 was a favorite 9 years ago ... and Andrew has posted the new EP-500 is more potent, even as a sealed unit.
