Hmmmm....Larry: since there are no outlet boxes along that common wall anywhere in the house, I'm guessing furring. (Excellent explanation, BTW.... something I certainly did not know before.)

I just want to take my existing speaker wiring, which runs from one end of the room to the other, drill a hole at or near the baseboard, and fish the wire up to where my rear surround speakers hang. This will do away with the need for wire covers and certainly meets the high standards of the internationally-known WAF.

Brett: we have names for people like you: Lucky Dog comes to mind...
