I have an inexpensive Phillips Home Theater System. It's your basic 5 speaker setup (including subwoofer).
Is there some way I can control the signal to the subwoofer individually? It just has straight speaker wire going to it. Perhaps I could put something in line between the receiver and the subwoofer? I am looking for a cheap/quick solution that gives me control.
Most surround sound systems have level controls for all the speaker including the subwoofer. Check speaker set up menus. If not then you can put a speaker level volume control in between the sub and Philips. This can be a L-Pad or a transformer based control. The kind that go in wall to control in wall speakers would work. This is one example http/www.parts-express.com/pe/showdetl.cfm?partnumber=260-252
