VR-S/3   REFERENCE GRADE POWERED SUBWOOFER
Extremely fast transient response combined with massive impact & high SPL levels.

The VR-S/3 powered subwoofer was engineered to be the world's fastest and clearest design, eliminating the coloration found in conventional subwoofers due to slow speed and hangover. VSA has worked for a year on an Extreme-Duty 12" woofer design of heroic specifications and a 900-watt (peak) High Current amplifier capable of fast transient response at extremely high volume levels. We believe we have developed the most transparent subwoofer available, and then we designed it to easily integrate with any main speaker, in any type of application. After auditioning the VR-S/3, you will find that all other subwoofers sound like a low frequency "roar" without pitch differentiation

CABINET
The massively built enclosure was engineered to provide rock-solid stability at extreme volume levels, without adding distortion or coloration to the driver motion. The total weight of the system is 105lbs, amazingly stout for such a compact unit. A 2" thick MDF front baffle is combined with a complicated honeycomb interlocked bracing system. Internally, the 1" MDF walls are damped by 1" thick acoustic foam pads to provide the ultimate in sound deadening. Bass tuning is accomplished by a flared port tuned to 20Hz. Frequency response extends down to 16Hz (-6dB).

EXTREME DUTY WOOFER 
High volume, low frequency sound reproduction depends on volumetric displacement, high-speed transient response without hangover, and unlimited headroom. To accomplish these goals in an ultimate driver, we have selected a 12" cone made of aluminum, Nomex, and Kevlar honeycomb sandwich. Although extremely light (less than an equivalent thickness of paper), this cone will not flex or distort at any volume level. The cone is held in the cast aluminum frame with dual spiders and a thick butyl surround that allows a 2" excursion potential! To handle the 900-watt (peak) power, we have installed a 3" diameter voice coil bonded with aerospace adhesives that will not delaminate at high volume levels. The 25lb weight of this heroic driver is mainly in the motor system, allowing very high efficiency. This combination of design elements is not found in any other unit on the market!

AMPLIFIER
We selected a Class A/B design over the less expensive Class D switching design; our decision was based on reliability, depth , and tone quality. For this reason, our amp is very large and heavy, using a huge transformer and large power supply capacitors for high reserve power during peaks. The multiple output devices can put out 900-watt peaks before the onset of distortion, allowing our amplifier to drive the Extreme-Duty woofer to incredible volume levels without compression.
