Sorry guys, I found the report (http://www.ninjasreview.com/forum/showth...-for-all-of-you) and it's the mid-range drivers that don't have a high pass filter and are allowed to just roll off.

I'm not entirely sure if it really is the crossover, but my cable lengths are the same to both speakers and since I've never played them extremely loud I can't imagine there being any damage to the drivers.

Perhaps I should call axiom directly.
