A term that generally describes sound recordings with multiple channels and audio systems with multiple speakers placed around the listening area. The most common surround-sound configuration is known as 5.1, which means five full-range channels and one low-frequency channel, usually called the low-frequency effects (LFE) channel. A 5.1 surround-sound speaker system has three speakers in the front of the listening area, two speakers on the sides of the listening area, and one subwoofer. A 7.1 system adds two more speakers at the back of the listening area.
SVS offers a variety of complete surround-sound speaker packages, including the Prime Satellite 5.1 System, Prime Tower Surround System, Prime Bookshelf Surround System, Prime Pinnacle Surround System, Ultra Tower Surround System, and Ultra Bookshelf Surround System.
