Sorry to ask such a dumb question but here goes (new to all this). Wired my 10 gauge zip cord to the M80's lower set of posts and found the post hole size was not large enough for the wire. It frayed back and only a portion of the wire is in the hole. All the other Axiom speakers in my setup (VP150, QS8's and subwoofer had holes big enough to accept the wire. So, is the lower set of posts the correct posts for single wiring (or the top set) and should the hole have accepted the 10 gauge wire as did the other speakers.
