“EL” (Port Extension Length):
•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

GRILLE RECOMMENDATIONS
If you would like to put protective grilles on your W3v2, please make sure they allow sufficient clearance for the suspension of the speaker to operate properly (many “universal” grilles do not).
One way to be sure is to use the grille mesh inserts engineered by JL Audio for your woofer. These sturdy steel mesh inserts mount securely into the rubber gasket of the W3v2 and offer ample clearance for the suspension. Ask your dealer for details and pricing.
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This
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.
