Legacy Audio's Foundation Subwoofer:

Prepare to be amazed by the Legacy Foundation subwoofer, which delivers the lowest frequencies with exceptional clarity and minimal distortion. Despite its compact footprint of just 1.5 square feet, the Foundation produces natural bass weight and precise transient attack.


With patented compound passive radiator technology and a pair of Legacy's renowned long throw 12" woofers, the Foundation delivers a forceful and dynamic bass response without the usual mechanical shuddering found in other subwoofers. Its exceptional tonality and bass definition surpass expectations at this price level.


Powered by ICEpower® amplifier technology, the Foundation benefits from 30 amps of peak current, providing tight control over the 3-inch voice coil within each cast-frame woofer's massive 30 lb magnetic structure. We invite you to compare the Foundation with any competing subwoofer—we are confident you'll be astounded by its performance.
