* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** 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".

ENCLOSURE SPECIFICATIONS |
•
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
high-quality satellite speakers and amplifiers. We do not recommend the
use of this subwoofer with a passive crossover (coil), as this type of
device will adversely affect performance. |

| SAFETY
NOTICE! |
| Prolonged
exposure to sound pressure levels in excess of 100dB can cause
permanent hearing loss. This highperformance 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. | |
