Thanks for the clarification Dane. I have not heard of the "Signature 7NT" in-wall speakers and thought perhaps you were referring to the standard 7NT model- hence my apologies in advance. I would guess they are not designed to be mounted in a ported enclosure (or wall) if they are true "in-walls". Take SLL's advice and calibrate using the Radio Shack meter-- it will make a big difference in performance. Keep working at it- hopefully it will all gel for you soon.
