This has been mentioned quite a bit in another thread but I want some specific info for my setup. Presently, I just have one sub, it is a PDR 10. I also have a little 60 watt Aiwa 8" sub that is being unused. This sub obviously is not as good as the Paradigm. Would it be best to leave my bass (surround)directed to the Paradigm (located near the front) or go ahead and add the Aiwa into the surrounds and set them to large? It is going to be a lot of extra wiring considering the rear sub will be a distance from the front and that I am going to be running high level. Will this be worth the effort or am I going backwards? I also have an old PL receiver. Is it worth hooking up a rear center as well? Or should I just put this junk on ebay?
