Is there any reason why the speaker wire running to my surround speakers has to be the same length? In order to conceal the wires, I will be running the wire to the surround along a side wall. Obviously, the distance to the surround farthest from that wall will necessitate a longer wire. So, should both surround wires be made longer so they are of identical length, or is it OK if the length to one is shorter than the length to the other? Thanks for the input, Todd K.
