MEDIUM GRAY (MINIMUM):

LIGHT GRAY (OPTIMUM):

DARK GRAY (MAXIMUM):

BLACK (WARRANTY VOID):

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.

This zone represents the best compromise between long-termreliability,high-outputandlow-distortionperformance and is centered on each woofer's continuous power rating (as published in its specifications). In this zone,you will be taking full advantage of the woofer's optimum,low-distortionperformance range without undue risk of failure.

In this zone, low-distortionoutput andlong-termreliability will be compromised (especially by an aggressive user). 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 closer you are to the black zone, the higher the likelihood of driver failure. Operate with caution.

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.

JL Audio offers an extensive line of high-performancesubwoofer 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 powerwithout 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.

Subwoofers

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-bassperformance 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 ahigh-qualityenclosure 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-frequencyextension. 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.

If you decide to build one of these enclosures yourself, you must have the construction of the box inspected and approved by your authorized JL Audio dealer in order for the 1 year limited warranty to be valid. Please read the warranty information carefully.

*Xmax specifications are derived via one-wayvoice 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 measured with the voice coils in series, for parallel-wiredspecification divide Re by 4. All other specifications remain the same.

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performancespeaker 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 above 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 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 acount.

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). Likewise, when using three subwoofers in a common enclosure simply triple the required volume

and, in the case of a ported enclosure, use three times the recommended port(s).

We recommend the use of this speaker in a bi-amplifiedsystem usinghigh-qualitysatellite speakers and ahigh-qualityamplifier. 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.
