5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres.[1] It uses five full-bandwidth channels and one low-frequency effects channel (the "point one").[2] Dolby Digital, Dolby Pro Logic II, DTS, SDDS, and THX are all common 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music.[3]

All 5.1 systems use the same speaker channels and configuration, having a Front Left (FL) and Front Right (FR), a Center Channel (CNT), two surround channels (Surround Left - SL and Surround Right - SR) and the low-frequency effects (LFE) channel designed for a subwoofer.[4][5]
