There are many good subs in the $500-750 price range Jasper, if you want to stick with Axiom, you'd find most guys recommending the EP350 over the 175 for it's greater impact and range. If you go through the factory outlet you can bring the cost down 10% btw. Many of us here, do in fact, use non Axiom subs as there are a lot of good, competitively priced subs out there.
If your really mainly focusing on music though(outside of very low fq church organ type), the EP175 may be fine, but I've never heard one so maybe someone who has can provide some details on it.
Also, welcome!!
