A: For our purposes, a home theater system consists of a TV, a home theater receiver, a set of surround speakers (typically between five and seven), and a subwoofer. The receiver is the "brains and muscle" of the system, sending power and audio signals to each speaker, and video to your TV. Learn more about the components you need for a home theater system, and see our article for other ways to get great sound if a full home theater system won't work in your room.
