JL AUDIO 13W3v3-2 - 34,5cm Subwoofer

13W3v3-2
W3v3 13.5-inch Subwoofer Driver (600 W, 2 ohms)

• If you have the space, it makes a tremendous sense to maximize your subwoofer system's piston area to enhance efficiency (and output). It gets even better when the larger driver delivers additional power handling and excursion. For the preceding reasons, the 13W3v3 can be the best choice for those seeking high output with great sound quality at medium power levels.
• As with the smaller W3v3's, several exclusive JL Audio technologies and proprietary assembly techniques are applied to the 13W3v3 to enhance linearity and reliability.
• The 13W3v3-2 is best used with amplifier power in the 150W - 600W range and is optimized to operate in a moderate size 1.75 cu. ft. (49.6 l) sealed enclosure, or a 2.5 cu. ft. (70.8 l) ported enclosure.

Enclosure Notes
* The enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) 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.
* 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.

Safety 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.
