Hi, I have the AX500A 165 watt sub is there any were to get info on it? I was thinking that it is a little old and dated now and was thinking of updating to the EP175. Do you think I would hear a big difference between the 2 subs or is the AX500A a really good sub?

Thanks

You can email Axiom for the specs of the 500. I'm not sure how it compares to a 175, I've never heard the old Axiom subs.
