I just bought a Pioneer D514, I know not the best but I couldnt really aford a HK like I wanted. Anyways I'm using some cheap surround sound speakers from my old dvd system, but changed the fronts L and R to some older Kenwood 8" with a tweeter. What brand of speakers and size would sound good with the poineer? Also looking for a good cheap subwoofer, probably a powered one. Suggestions? Thanks
