I don't want to sound like I'm an Axiom fanboy, but several things concern me about that sub:

--With 158 ratings, it's not rated very high,

--the frequency response is rated to 28Hz, but with no +/- tolerance listed, that's pretty much worthless, and

--the Velo has a 185 watt am VS. the 300 watt amp in the Axiom.

--Also, if it matters, the Axiom is available in other finishes than black....
