Hey Josh, welcome, make sure you take my Axiom Polls on my website if you haven't already I'm curious about your question also, I got my Axiom speakers from the Factory Outlet about 6 months ago and mine looks just like the EP350 on the product page, with the black center on the woofer. Man I hope they didn't improve the woofer design, although I like my EP350, that would upset me

I know the EP350 says it has an Aluminum Woofer, and I assume the EP500 does also, but the product page does not come right out and tell you that, well I guess you got lucky, maybe they put EP500 guts in your EP350?
