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.

HGS-15X

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. HGS-12X

Dual Tandem Voice Coil - Linear Motion

Non-linear cone movement causes a high level of mechanical distortion and sloppy, muddy bass performance. Velodyne conquers this common cause of distortion with its unique Dual Tandem Voice Coil design. This system creates a linear excursion of 1¼” peak-to-peak with a 2” maximum. A two section magnetic structure in a push-pull configuration with a two segment voice coil wound out of phase generates less than half the distortion of conventional motor designs, and is capable of four times the heat dissipation, contributing to Velodyne’s distinctive tight, accurate, low distortion sound.
