•  The enclosure recommendations listed are external dimensions ‘Mlich assume the use of 3/4″ (19mm) thick material. If you are using 5/8″ ( 16mm) thick material, subtract I /4″ (6.5mm) from each dimensioo. 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 volum e displacement, port displacemerit 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 volum e and, in the case of a ported enclosure, use two times the recommended port(s).
•  We recommend the use of this speaker in a bi­amplified system using high-quality satellite speakers and amplifiers. We do not recommend the use of this subwooferwith a passive crossover (coil),as this type of device will adversely affect performance .
• Prolonged exposure to sound pressure levels: in excess of IOOdB 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 vehide. it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorplan or the frame of the vehicle with a large diameter washers for reinforcement. If an enclosure is: not finally attached. it can become a projectile in a collision. This is particularly important in a hatchback. s:tation wagon, sports utility vehicle, or van.

RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR .Qli.E SUBWOOFER DRIVER:

MEDIUM GRAY (MINIMUM):
From ii. reliability s.tandpoint. this zone represents a very comfortable operating power range for each driYer. This level of power will not s.tress the woofer but will not extract al I of its performance potential. either.
Us.e of less. than the minimum power level will not damage the woofer, but may res.ult in until.tisfactory performance.

MEDIUM GRAY (MINIMUM) :
From ii. reliability s.tandpoint. this zone represents a very comfortable operating power range for each driYer. This level o

DARK GRAY (MAXIMUM):
Slightly more SPL will be gained by pushing the power into ch is zone. but typically not more than 2dB. compiled 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 le;,el of power. In this. zone. there is ii. very high probability diet the driver will filil 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-performance subwoofers driven 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 th at power without drastically overdriving the ampUfler{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.
