**Efficiency (1W/1m) is not 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” !
•The enclosure recommendations listed 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 are net internal volumes!
Box volume displacement, port displacement 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 volume and, in the case of a ported enclosure, use two times the recommended port(s).
•We recommend the use of this speaker in a bi- amplified system using
! ! CAUTION ! !
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.
