• 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

230 mm

*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” !

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.

! !	Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance
CAUTION	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.
