I sent my Promedia 5.1 sub in for repair, and 5 months later I still didn't have it. I don't know if they couldn't fix it or not, but they sent my a brand new set of Promedia 5.1 Ultras. So now I have 5 extra speakers laying around. Is there anything I could do with them? Was thinking about getting a Klipsch sub, but then I wouldn't have the control pod. Any way to splice/amplify them into my Ultra's?
