  G22 Direct Servo subwoofer
Dual opposed 12" sealed audiophile sub with 800WRMS amplifier


Dual Opposed Mounting and Direct Servo Technology

Dual opposed subwoofers mount two drivers on opposite walls of enclosures in an effort to reduce the reaction force exerted onto the enclsoure from drivers . However, the disadvantage of the conventional non-servo dual opposed subwoofers is the boxy bassinside the enclosure is still audible with re-radiation via the cones. With our patented Direct Servo technology, it enables precise control over the cone to resist and dissipate any energy acting on the cone and the so-called re-radiation of boxy bass coloration can be reduced by up to 10x in energy. This is essential for tight, dynamic and accurate bass. It also counteracts many different driver non-linearities and allows us to use lighter drivers which avoid the need for excessive amounts of amplifier power.

Some of the benefits of Direct Servo include:

  • Dramatic reduction of the re-radiation of bass from inside the box, which is commonly referred to as boxy bass.
  • The effects of thermal compression are eliminated under normal operation
  • Higher efficiency allowing output which would normally require a more powerful amplifier
  • Deep bass extension can be achieved using a low mass driver with superior transient response
  • Mechanical and thermal memory effects are reduced, further improving transient response
  • The (temperature-independent) effective in-box Q value is 0.3 (0.1 for driver itself) resulting in much tighter and accurate bass than conventional designs with typical value of 0.8-0.9 (and even higher when voice coil becomes hot)

HX800XLR3 Amplifier and Dual DS1204 Driver

G22 uses our dual Hypex-module HX800XLR3 servo amplifier and two DS1204 driver. DS1204 features anodized aluminum cone, a 2" voice coil with linear excursion range of +/- 15mm.

The quickguide of the HX800XLR3 amplifier can be found here . The installation guide can be found here. The response curves with various extension frequency/damping combinations of both amplifiers can be found in our EQ page.

The sub comes with standard screw-in rubber feet.

Introductory price includes freight shipping to 48 US continental states only. Shipping to other region or country should inquire us for actual cost.

High efficiency horn speakers may require custom modification for gain matching. Please inquiry us when using our subs with horn speakers.
