• 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 acount.

• 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). Likewise, when using

three subwoofers in a common enclosure simply

triple the required volume and, in the case of a

ported enclosure,

use three times

the

recommended port(s).

• 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.

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.

All specifications are subject to change without notice.
