HGS-X Series 
HGS-10X, HGS-12X and HGS-15X 
 
 
Since 1983, when Velodyne revolutionized subwoofers with 
its patented High Gain Servo
 technology, reviewers and 
consumers have praised their superior performance. The 
tradition continues with the HGS-X Series – delivering 
Velodyne’s world-famous powerful, accurate, low distortion 
bass from incredibly small, easy to place or custom install 
cabinets. The High Gain Servo system controls Velodyne’s 
unique Dual Tandem Voice Coil drivers powered by a Class 
D amplifier that delivers more than 3000 watts of peak 
power. Without question, the HGS-X Series are the most 
powerful, precise and affordable servo-controlled subwoofers 
on the market today.

 Amps - Unprecedented Power 
To power these incredible subwoofers, Velodyne uses a “digital” switching 
amplifier, capable of producing 1250 watts RMS and over 3000 watts peak. 
Unlike conventional designs, the HGS-X Series incorporates Velodyne’s 
patented Energy Recovery System that converts over 95% of the incoming 
current to usable power with minimal heat buildup. 
 
 
 
 
High Gain Servo - Lowest Distortion 
Only Velodyne’s High Gain Servo technology can deliver less 
than 1% distortion all the way down to 20 Hz and below. This 
patented Velodyne technology utilizes a tiny sealed 
accelerometer that is mounted to the voice coil, measuring the 
actual motion of the speaker cone 3,500 times a second. The 
data is fed into a processor where it is compared to the input 
signal and any discrepancies are corrected instantaneously. The 
distortion that produces the boomy, muddy bass of competitive 
subwoofers is virtually eliminated in the HGS-X Series. The 
result is deep, dynamic bass that you can actually feel.
