Hi there, I've had the Promedia 2.1 for about 8 years, good sound but one problem: the control pod, so the whole system ended up stored in the basement. Now I bought a receiver: Pioneer VSX-822-K with a nice pair of Polk tower speakers. I miss the bass of my Klipsch. Is there a way to connect the subwoofer from my Promedia 2.1 to the Sub-Preamp in my receiver? Thank you all.
