NVX VS-SERIES
THANK YOU FOR CHOOSING NVX
Congratulations on the purchase of your new NVX subwoofer. The VS-Series V2 subwoofer
you hold in your hands is the culmination of an extensive research, development and real
world testing process. While this isn’t the easiest way to build a sub, the time and personal
attention we dedicate reects in the quality and performance of the nished product. We are
proud to build NVX subwoofers and are condent you will be proud to own one.
We have incorporated many features in the VS-Series V2 that will separate NVX from the
competition. Utilizing our engineering strengths and woofer knowledge, we created VS-Series
V2 to deliver amazing SQ (Sound Quality) and performance while providing the best value in
its class.

The enclosure designs listed below will give you the best possible
performance from your VS-Series V2 subwoofer. NVX subwoofers
are optimized for use in both ported and sealed enclosures, each of
which has distinct sonic characteristics.
PORTED BOX
Ported boxes are the enclosure type we recommend for
optimum performance of your VS-Series V2 Subwoofer.
A ported box features a vent or port to couple the woofer’s back-
wave with the front-wave. This results in markedly improved
efciency and low frequency response.
These enclosures are somewhat larger than the sealed alternative.
ENCLOSURES
SEALED BOXES
A sealed enclosure offers improved acoustic suspension and
cone control, which reduces distortion and increases the power
handling capabilities of the subwoofer. They are smaller than
their ported counterparts, and offer atter bass response with
more consistency across the frequency range.

SUBWOOFERS
FEATURES
OPTIMIZED MOTOR STRUCTURE
To begin with, we used motor analysis tools to effectively create the needed force to
drive the woofer in the most linear fashion. The BL (Motor Force) was optimized to allow
the VS-Series V2 to operate in smaller sealed and ported enclosures. The VS Series V2
will reach its’ performance potential in enclosures ranging from 0.35 cuft to 2.75 cuft.,
with a mounting depth as little as 4.50 inches.
ALUMINUM SHORTING RING
Perhaps the most distinguishing component of the VS-Series V2 subwoofers is the
innovative aluminum shorting ring system. This technology prevents a rise in inductance
caused by the movement of the driver, which has several positive impacts on the
subwoofers’ performance:
● Improved power delivery to the voice coil
● Decreased inductive distortion
● Improved cone linearity
● Improved high-end extension
● Decreased risk of overheating
WHAT IS THIS SHORTING RING?
The shorting ring is a conductive aluminum ring placed in the air gap between the
pole piece and the voice coil former to reduce inductance. Inductance can best be
understood as the change in magnetic energy that occurs as the voice coil moves in
and out of the air gap. In most subwoofers this energy is absorbed by the voice coil,
causing impedance rise, introducing distortion and reducing the woofer’s ability to play
at the top of the bass spectrum. In the VS-Series V2 subwoofers, the shorting ring simply
absorbs changes in inductance, optimizing the sound quality, output potential and
frequency response of the woofer.
SO WHY DOES IT WORK?
● Improved power delivery to the voice coil
Any increase in inductance correlates to an increase in voice coil impedance, meaning
increased resistance to the input power. By preventing inductance rise, we effectively
increase the amount of power carried to the voice coil, increasing the output potential
of the woofer with each given watt.
● Decreased inductive distortion
When inductive energy is introduced into the motor structure, it causes the subwoofer
to produce sounds and artifacts at higher frequencies around the 500-1,000 Hz range.
Our Aluminum shorting ring absorbs these changes in inductive energy, resulting in
crisp, distortion-free bass.
● Improved cone linearity
A great deal of care was taken during the research and development process to ensure
that the movement of the cone is as linear as possible. Since inductance is a change
in magnetic energy, it’s easy to see how undesired inductance can alter the movement
of the cone. By using our shorting ring, we absorb these changes in magnetic ux and
prevent modulation of the cone resulting in tighter, more accurate bass.
● Improved high-end extension
The low-pass lter in a standard crossover network is basically just a coiled conductive
wire with an iron core very similar to the design of a voice coil. When the inductance of
the voice coil increases, it begins to lter out notes at the top of the woofer’s frequency
range. Our aluminum shorting ring eliminates these variations in inductance, allowing
the woofer to play as it was intended.
● Decreased risk of overheating
In addition to the positive impact the shorting ring has on the subwoofer’s sound
quality, it also acts as an effective heat sink to carry heat away from the voice coil, which
contributes to improved performance and durability.
IF IT’S SO GREAT, WHY DON’T OTHERS USE IT?
Where we see an opportunity to build a better product, other manufacturers see an
opportunity to maximize prots. Shorting rings require additional materials and add
complexity to the manufacturing process. Rather than skimp on the shorting ring
and make inferior woofers, we ultimately decided to create a masterpiece. The most
experienced engineering team in the industry has painstakingly designed our VS-Series
V2 subwoofers, and we rmly believe that you will hear the difference.
