I have a sub that is in a back corner of my living room, far from my receiver. With this layout, I can either run a sub cable through the wall, across my attack, and back down the rear wall to my sub, or I could just buy a Bluetooth adapter of some sort. Is there any big drawback to the latter, aside from the price? I'm guessing Bluetooth would result in loss of signal quality, but running a sub cable across multiple other electrical cords probably would as well.
