Subwoofers

owner’s manual

Congratulations on your purchase of a JL Audio subwoofer component. Your JL Audio subwoofer is a

precision loudspeaker which has been engineered to produce the highest quality sub-bass performance

in your vehicle. Authorized JL Audio dealers have extensive technical information for many different

applications of your new speaker. They also have the knowledge, skills and tools to build a high-quality

enclosure that will maximize the performance of your speaker. We highly recommend that you have

your enclosure built by an authorized JL Audio dealer.

Inside you will find specifications and two recommended enclosures for your speaker; one is a sealed

enclosure, the other is a ported design. Both types of enclosures will give you excellent sound quality and

low-frequency extension. The sealed enclosure is a better choice if space is extremely tight, but the ported

enclosure will produce 3dB more output at the same power if you have the extra space to work with.

* Xmax specifications are derived via one-way voice coil overhang method with

no correction factors applied.

** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output

capability and should not be used as a comparison to other subwoofers to
determine which one is “louder” !

*** Re (DC resistance) is mea sured with the voice coils in series , for parallel-

wired specification divide Re by 4. All other specifications remain the same.

• The W6v2’s employ a pole vent to remove heat and pressure from the inside of the

speaker. This vent is located around the JL Audio badge at the rear of the speaker. A
minimum distance of 3/4-inch (20mm) 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 are external dimensions which assume the
use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract

2

1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less

2

than 5/8" (16mm) as this may compromise the rigidity of the enclosure.

• All enclosure volumes listed are net internal volumes! Box volume displacement,

port displacement and brace displacement must be added to obtain the final gross
internal volume. All enclosure dimensions listed have already taken this into account.

• When using two subwoofers in a common enclosure simply double the
required volume and, in the case of a ported enclosure, use two times the
recommended port(s).

• We recommend the use of this speaker in a bi-amplified system using high-
quality satellite speakers and amplifiers. We do not recommend the use of this

3

subwoofer with a passive crossover (coil), as this type of device will adversely
affect performance.

CAUTION

!! !!

Prolonged exposure to sound
pressure levels in excess of 100dB can
cause permanent hearing loss. This high­performance 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 impor tant in
a hatchback, station wagon, sports utility
vehicle, or van.

W6v2 TECHNOLOGIES W6v2 TERMINAL JUMPER SYSTEM

Please note that the W6v2 is a dual voice coil driver.
BOTH voice coils must be connected to the amplifier
(in series or parallel) for the speaker to operate
properly. To accomplish this, each W6v2 features a
pair of main input connection push-terminals and
four voice coil configuration tab terminals. These are
located behind the main input connectors and are
used to interconnect the dual voice coils in one of
two ways: Diagram A shows a series connection (8Ω
nominal impedance per speaker). Diagram B shows
a parallel connection (2Ω nominal impedance per
speaker) and is the way the speaker is configured at
the factory. After verifying that the tabs are properly
configured using the supplied jumper(s), connect
the amplifier’s output wires to the W6v2’s main
input push-terminals and install the speaker into the
enclosure.

Warning! Failure to properly connect the
configuration tabs will result in no output and may
damage the speaker.

1 - Customizable Trim Ring: (U.S. Patent
#D480,709) This removable ring can be painted to
match the installation theme, if desired.
2 - W-Cone™ (U.S. Patent #6,496,590) The
W-Cone™ unit-body cone assembly delivers
astonishing cone-stiffness with minimal mass.
3 - Floating-Cone™ Attach Method
(U.S. Patent #6,501,844): This unique assembly
technique ensures proper surround geometry in the
assembled speaker for better excursion control
and dynamic voice coil alignment.
4 - Plateau-Reinforced Spider Attachment
(U.S. Patent #6,118,884): A derivative of JL Audio's
famous VRC technology, this bulletproof suspension
attachment relieves stress from the spider material
at high excursions for enhanced reliability.
5 - Pole and Cone Venting (Patent-Pending):
Vents at the neck of the lower cone body work in
conjunction with the pole vent at the rear of the
motor structure. These vents effectively remove hot
air during high power operation to improve sound
quality and reliability.

6 - Forced-Air-Cooled Aluminum Alloy Frame
(U.S. Patent #6,219,431, #6,229,902 and
#D472,891): Cool air is directly pumped onto the
voice coil of the speaker through slots between the
frame and top-plate. This enhances power handling
and sound quality by minimizing dynamic parameter
shifts and power compression.
7 - Highly Optimized Motor Systems:
Highly linear, FEA-optimized motors reduce audible
distortion and improve transient behavior for
superior sound quality and dynamic stability.
8 - Large, Progressive-Roll Spiders:
Optimized to control the long excursion of the
W6v2's without limiting it.

9 - Engineered Lead Wires and Connectors:

Connections for both voice coils terminate in a
unique configuration block on one side of the
basket.The extruded lead wire casing and
carefully engineered attachments ensure controlled
behavior and improved reliability under extreme
excursion demands.

Diagram A: Series Connection (8Ω):

Use one jumper from “VC1–” to “VC2+”

Diagram B: Parallel Connection (2Ω):

Use two jumpers... one from “VC1–” to “VC2–” and
one from “VC1+ to “VC2+”.
