I’m a newbie to the forum. I’ve done some reading but I haven’t found this particular problem talked about. I recently bought a two-story house and I’m planning to install in-ceiling speakers. The in-ceiling speakers will be the rear channel on a 5.1 system. The room is located on the first floor, so attic space is out. I’ve figured out that the best option is behind crown molding. I would prefer to do it all via the ceiling but the ceiling joists run parallel to the wall that the TV is sitting on. I can either go left, right, or both with the wire. If I go right, the run is about 35 feet but it has to run next to a 220V wire that is inside ¾” conduit. If I go left, the run is about 70 feet and no conduit. If I run the wire next to the conduit will I get the 60Hz hum?
