FS-7.0/SB-800 The magic behind Atlantic Technology's FS-7.0/SB-800 seven-channel soundbar / subwoofer system is pictured to the right with it's grille removed. The unique 40 inch long Atlantic Tech FS-7.0 is the world's first 7-channel surround bar speaker. Two 4 x 6 inch speakers on the front baffle each feature a dual voice-coil driver that handles the left (or right) front channel and "half" of the center channel. The side-firing surround drivers are triple voice-coil drivers, handling both the 5.1 and 7.1 surround channels, and a portion of the left or right front channel for added spaciousness. You can buy your Atlantic Technology FS-7.0 7-channel sound bar speaker and the separate Atlantic Technology SB-800 8-inch 100-watt powered sub (pictured below) at Amazon.com.
