Hi

At the moment I have a surround system (5.1) with a subwoofer that plugs in and has a couple of inputs (1 x optical) (1 X coaxial) and (2 X phono). I want to purchase something like ONKYO TXSR577 HOME CINEMA RECEIVER. I have PS3, Xbox, Wii and a pc that I want to plug through, I have 5 other speakers, but can I use the subwoofer or will I need a new one? What is meant by active and passive subwoofer, any advice would be greatly appreciated, thanks in advance
