Finally got around to installing the left speaker in 2nd bedroom. Not hooked up yet because I plan to use flat wire that sticks to wall. The wire I have is labeled Aurum but looks identical to Ghost Wire sold by Sewell. Here are the instructions for running Ghost Wire. My plan is not to use the big terminal blocks sold by Sewell on the grounds that they are big and ugly. Instead, I plan to fold over just a bit of wire at the end (that way I can get behind the sticky part on top surface) and solder small 16 or 18 gauge wires to it. At least up by the speaker.
