I'd like to re-position our TV and surround sound speakers in our living room. Right now I've just got speaker wire stapled to the baseboards running around the room, and a few network cables laying on the floor for the xbox and Dish receiver, it's all ugly. Where I'd like to place the TV, the satellite cable outlet is across the room, and speaker wire would have to cross 1 (possibly 2, depending) doorways. Floor is hardwood. Below is a second living area, standard sheetrock ceiling down there. No attic above, it's a tall ceiling that is flat against the roof (if that makes sense), and the wall where the TV will be goes up to the level of the ceiling on the next floor up, it's very tall. There is a bedroom on the other side of the wall where the TV will be. So, what are my options for running wires? Does it come down to running those plastic sheath things, or cutting holes in the walls in order to get things where I want them? What's the best way to get around a doorway? The doorways in question have no frame.
