Because your receiver has a separate woofer output all you have to do is connect the woofer speaker there. But if there isn't any separate connection then the woofer would need L-C filter for it (which might be cheaper just to get a completed unit).
I've got a 10inch sub laying around and would like to make it a sub for my PC. Can this be done? If so, how would I go about doing this? I've tried some shoddy setups just to see if I could get it working, but I could not figure it out. I have harman/kardon speakers with a subwoofer plug built into the back. I've never had or seen the insides of a computer sub before so I am not sure of how to make it. Any special wiring involved?
Thanks in advance
