Binding post issue, sounds like the bi-amping capability to me. You can do 1 of 2 things here, I believe. If your not going to bi-amp you can buy banana plugs that allows you to plug one plug into the top of another. I know those that Axiom sells that are 2 plugs in one piece allows you to do that. Another thing you can do is special order them from Axiom and have them install the 4 posts.
