o w n e r ’ s m a n u a l  
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.  
 
All specifications are subject to change without notice.

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.  
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 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).  
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.  
• 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):  
BLACK (WARRANTYVOID):  
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.  
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.  
Subwoofer  
drivers  
operated  
at these levels of power are NOT  
covered under warranty.  
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.
