Massive DSP Subwoofer from Legacy Audio
The Goliath XD's drivers feature silver/graphite/Rohacell cones and vented motor structures, and each is powered by a dedicated 500-watt ICEpower amplifier. The sub's DSP controller allows for low-pass crossover settings with slopes ranging from 6dB to 48dB per octave. The algorithm mates the response of the 15" drivers to the enclosure's tuning frequency set by its twin 15" custom-weighted passive radiators. Eight parametric filters can be adapted to tailor the subwoofer to the room in which it will be used, and the DSP's synchronization feature can align up to four subwoofers in time. The 275-pound Goliath XD extends down to 12Hz and offers
130dB maximum output. "The visceral bass from the Goliath XD rises and falls so
quickly in the room that boom and droning are virtually nonexistent, " claims Legacy
Audio. The Goliath XD is available in a wide array of finishes. |
