When I (finally) had all the pieces of my home theater, and set it up, I was in the middle of a remodel. I had open walls, and put in all the cabling (16-gauge zip cord) I needed, and right to the places I wanted the speakers (5.1 back then). I'm about to relocate, and I don't have the luxury of open walls this time. Way, way back I was a telephone company installer, and back then, we were expected to crawl under houses where possible to make "invisible" installations - not true at all now. I'm afraid I'm just not willing to go to those extremes for my speakers, and I keep hoping there is now a way to take advantage of wireless technology to set up four speakers (in a 7.1 array) without having to cable at all. Does anyone know of anything close? Any help would be appreciated.
