Legacy’s new 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.

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!

Ultra Long Throw 12″ Subwoofer

Foundation utilizes a pair of our ultra long throw 12″ subwoofers. This driver offers the highest Xmax available in its efficiency class, a 3″ dual 4 layer voice coil and a 480oz (30lb) motor structure. The powerful motor structure and dual 3″ voice-coils are required to keep the woofer’s heavy cone well damped electrically. The voice-coil leads are woven into the spider so they can’t slap the cone on large excursions. The internal ICEpower® amplifier’s current capability is an ideal match for the series/parallel load of the 4 voice-coils.

Fine Tuning

Foundation provides variable level control, continuous phase adjustment and a wide range of crossover frequencies. Also included is our unique blend control to finesse the transition in the overlap area from your main speakers. These controls will allow you to
tailor the sound of the sub to your room and integrate with your main speakers.


The XT-7 is a full range, 3-way floor-standing speaker featuring an aluminium rear bass reflex and curved shape side panels. Its unique design is based on a reinforced cabinet made of wooden “sculptured” multilayer panels, to achieve exceptional control over unwanted resonances.
Developed after ten years of research and manufactured by the best Italian wood-makers, this loudspeaker suitcases all its original beauty and its innovative technology. The carefully selected high-performance components allow ultra-low distortion and natural, well-balanced, smooth musical reproduction.


Equipped with SEAS custom-made woven polypropylene woofers for Gold Note, midrange, and an outstanding ribbon AMT tweeter, the XT-7 recreates a realistic, deep and wide soundstage, that expands far beyond the limitation of the listening room.
These loudspeakers have the power to highlight any High-End stereo system allowing you to rediscover your favorite music as if you’ve never heard it before.
