Is there a cable anywhere which I could use to extend the cable from the control speaker to the subwoofer? After reading these posts and everything I've gotten 8-pin DIN but obviously not the same connection as a PS/2 connector. I would like an extra 3-5 feet on this cable but can't seem to find the right female/male cable to extend this. If anyone could help me here it would be greatly appreciated.
