The Xtreme XD is a high-performance powered subwoofer built around a 15-inch Silver Graphite cone bonded to an ultra-stiff Rohacell layer, driven by a massive 35-pound magnet structure with a high-speed rubber suspension and high-temperature 3-inch voice coil. A 15-inch mass-loaded passive radiator operates in a 6th-order, back-EMF canceling alignment with a dynamic braking coil that counters driver overshoot during direction reversals. Internal amplification comes from a 1,000-watt ICEpower module. The result is deep, controlled bass to 16Hz with a maximum SPL of 123 dB at 1 meter.
The Legacy Audio Xtreme XD represents serious subwoofer engineering in a manageable form factor. At 120 pounds and just over 27 inches tall, it delivers performance that many larger subwoofers struggle to match. The 15-inch Silver Graphite cone is bonded to an ultra-stiff Rohacell layer and driven by a 35-pound magnet structure, giving the driver the combination of light mass and enormous motor force needed for both deep extension and fast transient response.
A 15-inch mass-loaded passive radiator operates in a 6th-order, back-EMF canceling alignment. This is the same approach used in Legacy's flagship Goliath XD, scaled to a single-driver format. The dynamic braking coil uses the driver's own back-EMF to counter overshoot as the cone reverses direction, eliminating the ringing and overshoot that cause boomy, one-note bass in lesser subwoofers.
Internal amplification comes from a 1,000-watt ICEpower module, the same switching amplifier technology used throughout Legacy's powered product line. ICEpower delivers enormous current reserves with virtually zero wasted heat, meaning the Xtreme XD can sustain high-output bass passages without thermal compression or protection circuitry limiting dynamics.
The rear panel provides comprehensive connectivity and tuning options. Inputs include LFE, left/right RCA, and balanced XLR. A continuously variable phase adjustment from 0 to 180 degrees allows precise time alignment with the main speakers. The Blend EQ provides 12 dB of boost or cut centered at 45 Hz, useful for correcting room-induced peaks or dips in the crossover region. The variable crossover sweeps from 40 to 100 Hz with an 18 dB per octave slope.
At just over 18 inches square and 27 inches tall, the Xtreme XD fits spaces where the larger Foundation and Goliath XD cannot. It works equally well in dedicated listening rooms, home theaters, and living spaces where visual discretion matters. The extensive finish options, from standard veneers through premium and exotic selections, allow the Xtreme XD to complement any room decor.
For rooms that demand more output or deeper extension, two Xtreme XDs running together offer the distributed bass advantage of multiple subwoofer placements while matching the output capability of a single Goliath XD. This approach also provides smoother bass response across a wider listening area by reducing the impact of room modes.
