All, Forgive me if this has been addressed, but I scoured the forum looking for a helpful post on this topic. Last May, I bought the HTitB Panasonic SC-Btt 195. After a few months, I got tired of how the Blu Ray Player/Receiver controlled the TV, so I opted for a new receiver that could handle all my HDMI inputs, and use just one TV HDMI input. I settle on the Pioneer VSX 522-k. So I am using the panasonic speakers with the pioneer receiver. The problem I'm having is that the Panasonic subwoofer connector is proprietary (and seems to be simple speaker wire like the rest of the speakers), and the Pioneer receiver looks to need an RCA connector. As you can see.... The sound absent the subwoofer is very tinny, and even worse when I try to play music through the system. Is there a part you may recommend for connecting the sub to the receiver without having to pony up for a pioneer sub? Also, anything else you notice I may be doing wrong would be helpful. Thanks again!
