I have a really basic problem. I just bought a used EP500 subwoofer, but I don't know how to connect it to the subwoofer line output of my receiver. I looked at the "manual" on Axiom's product page for the EP500, but it's not all that helpful. It refers to an XLR to RCA adapter, but I don't have such a thing. Any suggestions would be welcome.
