About the Goliath XD
The Legacy Audio Goliath XD subwoofer is Legacy's deepest performing subwoofer, designed to match the dynamic range of even the most efficient speakers. It features massive motors on dual 15-inch spun aluminum diaphragm woofers (some sources specify Silver/Graphite/Rohacell composite), paired with dual 15-inch custom weighted passive radiators for deep extension without port noise. This configuration delivers 130 dB of low distortion output at 1 meter, with bass that rises and falls quickly to avoid room boom and droning. Ideal for reproducing visceral kick drums, rolling kettle drums, and surging pedal notes. It includes dual XLR balanced inputs feeding high-power ICEpower amplifiers, with processing via external DSP like Legacy's Wavelaunch or XP-4080 for precise room correction, time alignment, and crossover settings. Available in various finishes including premium and exotic options, with a relatively compact footprint thanks to passive radiator design.
