• 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 multiple subwoofers in a
common enclosure you will need to
recalculate the enclosure and port
dimensions. For assistance please contact
your authorized JL Audio dealer or JL Audio
Technical Support at 954-443-1100.
• To obtain a 4Ω mono load using three
12Ω WØ’s you must wire all three
subwoofers in parallel.
• We recommend the use of this speaker in a
bi-amplified system using high-quality satellite
speakers and a high-quality amplifier. 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.

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.

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”. All other specifications remain the same.
