This looks like a great opportunity for in cabinet speakers. I'd probably go with M60's. I'm not sure if Axiom is making an in cabinet VP160 yet, but they do have an in cabinet VP180. I suspect they'd make you an in cabinet VP160 if you asked. As far as a sub in concerned, there's no where to hide one in that room, so I'd go big and good looking. EP600 is maple or rosewood?
