I moved into a new place and began the process of setting up my home theater system. I planned on feeding the speaker wire inside the walls, but found that was impossible (townhouse with cement walls between each one.) So now I have a pair of rear speakers on the wall (since I already punched the holes in the wall to hang them) with wire hanging to the floor. I'm looking for a system with a truly wireless set of rear speakers. The devices that they sell to make your rear speakers wireless won't work for me because I'll still have the wire running from that up the wall where I have them hanging. Any ideas?
