Designer’s Notes 
(From Bill Dudleston)

•Goliath XD is a carefully engineered subwoofer, capable of integrating with the fin-
est speakers. 
• Unlike many woofers that suffer from overshoot, Goliath XD applies a special EMF 
countering circuit, which increases power handling and radically reduces low fre-
quency distortion. 
• An enormous stacked magnet structure is custom fabricated to provide excellent 
sensitivity. This unit is bolted in compression to secure nearly 80 lbs. of motor struc-
ture. 
• Two separate high current 500 watt amplifiers (1,000 watts total) maintain control
 of Goliath XD’s multiple 15” sub-bass pistons. 
• The subwoofer alleviates the deep bass demands from compact satellite speakers,
 thus preventing low frequency strain due to long excursion. 
• TheXilica processor allows for precise control over Level, Crossover Frequency 
and Phase, allowing Goliath XD to integrate precisely into your system.
