Pioneer S-CR400-K Speaker System

I bought philips surround sound from costco and didn't want to mess with buying speakers for my old receiver. Accidently, I won Pioneeer central channel and two side speakers with it. When I hoocked up to my new receiver I realized taht it sounds way better than my cheap surround from costco. I returned philips and using those pioneer speakers. Central channel is great. Side speakers could be bigger. It will work perfeclty fine for a small room, but keep in mind that you will absolutely need Sub Woofer with these. I am still putting together my surrond. I may end up keeping central channel and buying four bigger speakers for sides.
