I have Logitech Z-560 speakers (4.1 speakers), and for some reason all the channels blew out. The subwoofer works fine, but all 4 channels no longer work. Yet all 4 speakers still do work. Is there any way i can buy just a logitech subwoofer or something else to connect the 4 speakers too? It seems like a waste of money getting an entire new speaker system when all the speakers still function.
