Long time Axiom owner. I just received my M3 Walnuts and was setting them up and ran into a subwoofer problem. I currently have 2 x EP500 v3. One of my subwoofer cables/adapters became damaged and I need to replace it. Problem is I'm a little unsure what to replace it with.

I have a Denon 3400H and I connected my subwoofers via a subwoofer cable. Problem is the end that plugs into the subwoofer low level input is too small and I had to purchase an adapter in order to plug it into the subwoofer's low level input. I just don't remember what the name or type of adapter it is. Just hoping someone can provide some assistance.

As well, rather than purchase an adapter, is there a cable that comes with an rca end that would fit into the receiver and the other end larger that would fit into the back of the EP500?
