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.

!! CAUTION !!
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.
• 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 1/4" (6.5mm) from each dimension. Do not use
any material with a thickness of less 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
subwoofer with a passive crossover (coil), as this type
of device will adversely affect performance.

MEDIUM GRAY (MINIMUM):
From a reliability standpoint, this zone
represents a very comfortable operating
power range for each driver. This level
of power will not stress the woofer but
will not extract all of its performance
potential, either.
Use of less than the minimum power
level will not damage the woofer, but may
result in unsatisfactory performance.
LIGHT GRAY (OPTIMUM):
This zone represents the best
compromise between long-term
reliability, high-output and low-distortion
performance. This power level is lower
thanthewoofer’scontinuouspowerrating
(as published in its specifications), but
you will still be taking advantage of the
woofer’s, low-distortion performance
range without undue risk of failure.
DARK GRAY (MAXIMUM):
Slightly more SPL will be gained by
pushing the power into this zone, but
typically not more than 2dB,compared to
the light gray zone.The subwoofer driver
is designed to operate safely up to this
power range, but not beyond. Operate
with caution.
BLACK (WARRANTY VOID):
We do not recommend operating
woofers at this level of power. In this
zone, there is a very high probability that
the driver will fail due to excessive heat
and/or mechanical stress.
Subwoofer drivers operated
at these levels of power are NOT
covered under warranty.

repair attempts, misrepresentations by the seller. This warranty does not cover incidental or
consequential damages and does not cover the cost of removing or reinstalling the unit(s).
Cosmetic damage due to accident or normal wear and tear is not covered under warranty.
This warranty is not transferable and applies only to the original
purchaser of the product from an authorized JL AUDIO dealer. Warranty is
voided if the factory-applied product serial number is removed or defaced.
Should service be necessary under this warranty for any reason due to manufacturing
defect or malfunction, JL AUDIO will, at its discretion, repair or replace the defective product
with new or remanufactured product at no charge.
Any applicable implied warranties are limited in duration to the period of the express
warranty as provided herein beginning with the date of the original purchase at retail, and no
warranties, whether express or implied, shall apply to this product thereafter. Some states
do not allow limitations on implied warranties, therefore these exclusions may not apply to
you. This warranty gives you specific legal rights, and you may also have other rights which
vary from state to state.
If you need service on your JL AUDIO product:
All warranty returns should be sent to JL AUDIO freight prepaid through an authorized
JL AUDIO dealer and must be accompanied by proof of purchase (a copy of the original
sales receipt.) Direct returns from consumers or non-authorized dealers will be refused
unless specifically authorized by JL AUDIO with a valid return authorization number.
Warranty expiration on products returned without proof of purchase will be determined
from the manufacturing date code. Coverage may be invalidated as this date is previous
to purchase date. Return only defective components. Non-defective items received will
be returned freight-collect. Customer is responsible for shipping charges and insurance
in sending the product to JL AUDIO. Freight damage on returns is not covered under
warranty. Always include proof of purchase (sales receipt).
RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER:
JL Audio offers an extensive line of high-performance subwoofer drivers to fit a wide variety of enclosure and power applications.When designing systems
with our drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power
levels listed in the above chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power
without drastically overdriving the amplifier(s). Make sure you factor system impedance and the total number of subwoofers into your calculations.
Adhering to these power recommendations will result in systems that are both reliable and enjoyable.
