Axiom Home Page Forums General Discussion Technical Questions What type of speaker wire terminal is this?

I just found a thread over on AV123 where they have mentioned that there was not enough room for dual binding posts like the epm-300 monoblock. They also mentioned that bare 12 gauge wire fits fine, or even using pins. I guess the pictures are misleading.
