Five surround sound speakers can be connected to a 5.2 receiver, as well as two subwoofers. For the surround sound speakers, there are five options: front left, front right and center. Seven channels are available for surround sound speakers, and two subwoofer channels. A 7.2 receiver can handle both. The 7.2 speaker arrangement is identical to a standard 5.1 setup, with two additional surround sound speakers at the back and one more in the back.
