The standard home theater setup consists of five to seven speakers and a subwoofer. The center channel speaker anchors the sound to the picture, and provides most of the dialogue and much of the special effects. The front left and right speakers deliver a wide soundstage, and work with your center channel speaker to reproduce on-screen action that moves to the left and the right, giving you a more realistic and exciting movie experience. The front speakers also act as the left and right stereo speakers when you listen to music.
