JL AUDIO 15W3v2 3
• 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 account.
• 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.
• 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.
RECOMMENDED ENCLOSURES
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.
