You can certainly use it, but it may not be ideal - I believe the sound bar is designed to simulate the entire surround sound experience. When you hook it to an actual surround driver, you'll probably notice the two fight each other. You'd probably be better off selling the sound bar and getting a nice surround set-up, assuming you still have this discount then. To be honest, it's been my experience that cheap speakers set up as a true surround system sound better than a super expensive system that's not a surround system. And by this I mean you are more immersed in the sound. For a good home theater, expect to shell out $2000+ for a receiver, Blueray, surround speakers, woofer, and front speakers. Then spend some dough on a good TV to make it worth watching. Having said that, in the last year, I sold off my big screen, got rid of my home theater and now just have a 32" 720p HD TV, cable and DVD. Can't say I miss the better system.
