High-quality home theater speaker systems try to recreate these aspects of professional theaters. For instance, the DVD player in a home theater system can separate the audio track into two, three or even five channels. DVD films often have 2.0 Dolby stereo and 5.1 surround-sound options for home theaters. Two speakers can be set up for traditional stereo sound, while a smaller central speaker can provide surround sound. For even better results, one can add a subwoofer for bass sounds and a satellite speaker placed behind the audience for complete surround sound.
A home theater system should also have a big television screen, preferably with a 16:9 wide screen ratio as found in professional theaters. A flat-screen television may be the best option for a typical home theater speaker system.
