Atlantic Technology"s FS-7.1 Surround Bar Loudspeaker is a high-performance 7.1-channel system in a single elegant, slim enclosure. The speaker can be either wall-mounted or placed on a shelf easily. The FS-7.1 features three 1" soft-dome tweeters, two 4 x 6" dual voice-coil LCR speakers, and two forward-angled, 3.25" surround sound speakers. Utilizing these drivers in an innovative array, the FS-7.1 creates impressive and convincingly three-dimensional theater sound from virtually any movie soundtrack, without the need for expensive on-board electronic processing circuitry or built-in amplifiers. For a complete home theater solution, pair the FS-7.1 with the Atlantic Technology SB-900 125-Watt Powered Subwoofer.
