Legacy Audio Foundation Subwoofer

SKU: Foundation Category: Brand:

The Legacy Audio Foundation is a dynamic dual subwoofer system, delivering essential lower frequency output. Foundation delivers incredible attack with ultra-low distortion and world-class definition utilizing only 1.5 square feet of floor space.

Legacy Audio Foundation Features and Specifications:

The lowest frequencies emerge from Legacy’s Foundation subwoofer with exceedingly low distortion. Exhibiting extremely natural bass weight and transient attack, Foundation requires a mere 1.5 square feet of floor space.

Implementing patented compound passive radiator technology and a pair of Legacy’s renown long-throw 12″ woofers, Foundation delivers a more forceful attack, rebounding without the usual mechanical shuddering present in subwoofers. Foundation offers exceptional tonality and bass definition previously unattainable at this price level.

Supercharged with ICEpower® amplifier technology, Foundation benefits from 30 amps of peak current, ultimately necessary to provide tight control to the 3-inch voice-coil within the massive 30 lb magnetic structure of each cast-frame woofer. Legacy invites you to compare this subwoofer with any competing subwoofer….we think you’ll be amazed!
