*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”.
***Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.

• 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.
