Cambridge Audio 5-speaker surround sound system plus subwoofer. This speaker system has 4 directional speakers, a central speaker, and a subwoofer. There are coaxial and optical connectors in the back of the control box. There is a remote control and there are coaxial cables included. I hooked up our flat screen television to this surround system using an HDMI to coaxial adaptor for it to work with HDMI devices. The connectors are older, but the sound is great.
