Legacy’s Deepest Performing Subwoofer!

The ultra-high performance Goliath XD subwoofer from Legacy will match the dynamic range of even the most efficient speakers.  Massive motors on dual 15″ Silver/Graphite/Rohacell woofers provide world class performance and will handily deliver 130 dB of low distortion output.  Bass pressure in rooms will rise and fall so quickly that room boom and droning is not an issue.  Kettle drums will roll and thunder, kick drums will have visceral punch and pedal notes will surge with this Goliath of a subwoofer.

The XLR input feeds dual 1,000 watt amplifiers. Recommended system controller/crossover is Legacy’s Wavelaunch processor.

Frequency range 12- 150 Hz with room correction and external crossover.
