7.1 Home Theater Speaker is the common name for an eight-channel surround Audio System commonly used in home theatre configurations. It adds two additional speakers to the more conventional 5.1 audio configuration. As with 5.1 surround sound, 7.1 Home Theater Speaker System uses the standard front, center, and Subwoofer Speaker configuration. However, whereas a 5.1 Speaker combines both surround and rear channel effects into two channels (commonly configured in home theatre set-ups as two rear surround speakers), a 7.1 Speaker splits the surround and rear channel information into four distinct channels, in which sound effects are directed to left and right surround channels, plus two rear surround channels.In a 7.1 Home Theater Speaker set-up, the surround speakers are placed to the side of the listener's position and the rear speakers are placed behind the listener. In addition, with the advent of Dolby Pro Logic IIz and DTS Neo:X, 7.1 Speaker can also refer to 7.1 surround sound configurations with the addition of two front height channels positioned above the front channels or two front wide channels positioned between the front and surround channels.
