Welcome to the extraordinary world of Altec Lansing high performance speaker systems. Many amplified speakers used for computer multimedia sound are undersized and underpowered. They lack the lower register of bass sound. Altec Lansing subwoofers are high powered and provide the low frequencies necessary to give full-bodied sound for all small tabletop speakers. Thunder, airplane maneuvers, car races, war scenes and music all come alive with the added sound of the subwoofer.The ACS251 subwoofer is especially designed to enhance low frequency response for all multimedia sound systems. Two amplifiers are used to drive a high compliance dual voice coil heavy magnet subwoofer speaker to achieve high audio power and low distortion. When installing your new ACS251 please be aware that low frequencies are non-directional and therefore the subwoofer does not have to be placed in any particular relationship to other speakers. The subwoofer can be placed under tables, behind couches or under your computer workstation Less
