W0v3 15-inch Subwoofer (500 W, 4 Ω) Sometimes, bigger is
better... For these situations, the 15W0v3 offers excellent
excursion capability, linearity and an overall performance
envelope that puts it right at the top of its price class. It
features a very beefy 2.5 in. diameter voice coil and our
patented Elevated Frame Cooling design for enhanced power
handling and reliability. The 15W0v3 is best used with amplifier
power in the 150W - 500W range and is optimized to operate in a
moderately sized 1.875 cu. ft. (53.1 l) sealed enclosure, or a
2.75 cu. ft. (77.88 l) ported enclosure. Detailed enclosure
recommendations can be found in the "Specifications" tab.

0.9301 Enclosure Notes * The W0v3âs employ a pole vent to
remove heat and pressure from the inside of the speaker. This
vent is located within the JL Audio badge at the rear of the
speaker. A minimum distance of 0.5 in (13 mm) is required between
the back of the speaker and any wall of the enclosure to allow
proper operation of the pole vent. * The enclosure
recommendations listed above are external dimensions which assume
the use of 0.75 in (19 mm) thick material. If you are using 0.625
in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each
dimension. Do not use any material with a thickness of less than
0.625 in (16 mm) as this may compromise the rigidity of the
enclosure. * All enclosure volumes listed above are net internal
volumes! Driver displacement, port displacement and brace
displacement must be added to obtain the final gross internal
volume. All enclosure dimensions above have already taken this
into account. * When using multiple subwoofers in a common
enclosure you will need to recalculate the enclosure and port
dimensions. For assistance please contact your authorized JL
Audio dealer or JL Audio Technical Support. * We recommend the
use of this speaker in a bi-amplified system using high-quality
satellite speakers and a high-quality amplifier. We do not
recommend the use of this subwoofer with a passive crossover
(coil), as this type of device will adversely affect performance.
* All specifications are subject to change without notice. Safety
Notice Prolonged exposure to sound pressure levels in excess of
100dB can cause permanent hearing loss. This high-performance
speaker can exceed this level. Please exercise restraint in its
operation in order to preserve your ability to enjoy its
fidelity. When installing a subwoofer in your vehicle, it is
extremely important to secure the enclosure firmly. We recommend
bolting the enclosure through the metal of the floorpan or the
frame of the vehicle with large diameter washers for
reinforcement. If an enclosure is not firmly attached, it can
become a projectile in a collision. This is particularly
important in a hatchback, station wagon, sports utility vehicle,
or van. Wall Thickness 0.75 in / 19 mm Front Baffle Thickness

Audio's proprietary Dynamic Motor Analysis system is a powerful
suite of FEA-based modeling systems, first developed by JL Audio
in 1997 and refined over the years to scientifically address the
issue of speaker motor linearity. This leads to vastly reduced
distortion and faithfully reproduced transients... or put simply:
tight, clean, articulate bass. Detailed Information: Since 1997,
JL Audio has been at the forefront of Finite Element
Analysis-based modeling of loudspeaker motors and suspensions.
This research is ed at decoding what we refer to as the
"Loudspeaker Genome"... a project ed at understanding the true
behavior of loudspeakers under power and in motion. A major
component of this integrated system is DMA (Dynamic Motor
Analysis). Starting with the 15W3 and the W7 Subwoofers in the
late 1990's and early 2000's, DMA has played an important role in
the design of all JL Audio woofers sold today, including our
component woofers. DMA is a Finite Element Analysis (FEA)-based
system, meaning that it takes a large, complex problem, breaks it
down into small solution elements for analysis and then assembles
the data to form an accurate, "big-picture" solution. DMA's
breakthrough is that it actually considers the effects of power
through the coil as well as coil/cone position within the
framework of a time-domain analysis. This gives us a highly
accurate model of a speaker's actual behavior under real power,
something that the traditional Thiele-Small models or other low
power measurements cannot do. Because DMA does not rely on a
steady-state model, it is able to consider shifts in the circuit
elements being analyzed. These modeling routines are intense,
requiring hours to run for a whole speaker. DMA is able to
analyze the real effects of fluctuating power and excursion upon
the magnetic circuit of the motor, specifically the dynamic
variations of the "fixed" magnetic field. This delivers intensely
valuable information compared to traditional modeling, which
assumes that the "fixed" field produced in the air gap by the
magnet and the motor plates is unchanging. DMA not only shows
that this "fixed" field changes in reaction to the magnetic field
created by current flowing through the voice coil, but it helps
our engineers arrive at motor solutions that minimize this
instability. Analyzing this behavior is critical to understanding
the distortion mechanisms of a speaker motor and sheds light on
the aspects of motor design that determine truly linear behavior:
Linear motor force over the speaker's operational excursion range
Consistent motor force with both positive and negative current
through the coil Consistent motor force at varying applied power
levels  Our ability to fully analyze these aspects of motor
behavior allows our transducer engineers to make critical
adjustments to motor designs that result in extremely linear,
highly stable dynamic loudspeaker motor systems. The payoff is
reduced distortion, improved transient performance and stellar
sound quality. Elevated Frame Cooling Summary: JL Audio's
patented Elevated Frame Cooling design delivers cool air through
slots directly above the top-plate to the voice coil of the
speaker. This not only enhances power handling, but also sound
quality by minimizing dynamic parameter shifts and power
compression. Detailed Information:Many speakers employ venting
techniques to enhance voice coil cooling. This is typically
accomplished by having big holes in the sides of the frame just
below the spider attachment shelf. While it provides a modest
cooling benefit, this low-velocity air-flow does not blow
directly or strongly on the voice coil. Our patented design
improves upon this cooling technique in a number of ways. By
elevating the frame above the top-plate of the motor (via
stand-offs integrated into the bottom of the frame) a narrow,
high-velocity air-path is created between the bottom surface of
the frame and the top surface of the top-plate. This air path
leads directly to the voice coil and then turns upward into the
spider air cavity. By utilizing the pumping action of the spider
through this focused air path, a large volume of cool air hits
the coil windings directly. Another important benefit is that the
upper surface of the top-plate (one of the speaker's hottest
parts) is directly exposed to cooling air flow, whereas on a
conventional design it is isolated from the air flow by the lower
flange of the frame. The elevated frame technology greatly
increases thermal power handling, reduces compression effects and
does so without any additional parts. Download  15W0v3-4 Product
