Summary: This is a great sound bar. No, it's not 5.1 surround, but it's close. I had to abandon my top of the line Energy (also made by Klipsch) speakers 5.1 system when we moved because I couldn't accommodate the wires for the rear speakers. This looked like a good alternative and it did not disappoint. The sub woofer ids a serious piece of equipment that fills my large room with thundering base.
