Polymineral Cone: The cone is a hemispherical
Polymineral design with an Inverted Structural Dome. It is very rigid with high
internal damping and excellent resistance to sunlight, pollution and moisture.
Double-stitched Pleated Surround:
This subwoofer uses a tough, flexible, highly tear-resistant polyester foam
surround. The surround is pleated and double-stitched to the cone edge, making
separation between them virtually impossible.
Inverted Structural Dome: The
Inverted Structural Dome replaces a conventional dustcap and locks into the cone
for unmatched structural integrity and greatly reduced cone flexing/resonance.
Voice Coil Former: The hi-temp
Kapton voice coil former protects against warped, rubbing voice coils.
Extended Pole Piece: The
extended pole piece creates a broad, symmetrical magnetic field for superior
power handling, precise voice coil control, and very low deep bass distortion.
Venting in the pole piece eliminates noise and distortion caused by huge amounts
of airflow created by cone excursion.
Black Plating: A blackened pole
piece provides effective heat transfer and cool operation for maximum power
Bumped Back Plate: The deep
bumped back plate lets the voice coil reach maximum excursion without
Perimeter Venting: The
perimeter venting cooling system continuously pumps hot air away from the voice
coils, replacing it with cool outside air.
Gasket: A rubber gasket insures
an airtight seal.
Enclosure Compatibility: This
woofer can provide extended bass in sealed and vented enclosures (please see the
"Enclosure Compatibility" section for more information on the
recommended enclosures). In addition, the woofer can be used in free-air
Recommended Sealed Box
Volume: When mounted in a sealed enclosure, the woofer delivers very
smooth bass response with good low-bass extension. The sealed box sizes
recommended by Kicker range from 0.5 cu/ft to 1.2 cu/ft. Within this range, the
ideal enclosure size recommended by Kicker is 0.5 cu/ft.
Recommended Vented Box
Volume: When mounted in a vented enclosure, the woofer can give you
more output than it will in a sealed box, at certain frequencies. The vented box
sizes recommended by Kicker range from 0.8 cu/ft to 1.2 cu/ft. Within this
range, the ideal enclosure size recommended by Kicker is 0.8 cu/ft. A vented
enclosure with an internal volume of 0.8 cu/ft uses one 3" diameter x 7"
Mounting: In addition to being compatible
with sealed and vented enclosures, the woofer can be used in free-air
applications. A free-air subwoofer is designed to be mounted on a baffle
board, which separates two areas of the vehicle. For instance, you could mount
this woofer to a board attached to the rear deck or placed in the trunk against
the rear seat. The trunk acts as the enclosure housing the subwoofer.
