I asked these questions on another forum and received no responses. A local pawn shop has a Pioneer sub for sale for about $150 or so. It's quite large and heavy and has a center channel with it. It's 220 watts, model # htv-sw2, bottom firing. The center channel speaker is model #htv-c2. The model year on the back of the center channel is 1998. I checked Pioneer's web site but found nothing about it. Being new to HT, how does the center channel hook up to this sub and then hook up to my receiver (there is no manual and this can not be returned if bought)? There are cables and some type of remote that controls it. I could be wrong but it appears the two pieces connect together with the supplied cables? If so, that would limit where I could put the sub? Would the two need to be connected together? Or could I connect them separately to my receiver (a Yammie RXV 630)? As you can see, I'm completely clueless as to how this particular combo works. They both appear to be in good shape. Would this be a good sub especially for this price? It looks like it might be able to put out some big sound (whether I need that or not, I don't know, remember my 1st ever set up). My room size is 12 X 18 with a 10 foot opening into the kitchen area on the left side of the room. Should I take the chance/plunge and buy this sub? Any responses would be appreciated. Thx, Frank Sorry, too late, but I meant to post this in the speaker section.
