At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Dual Voice Coils: For increased
system flexibility, this woofer has two 2 ohm voice coils. When the voice coils
are wired in parallel with each other, the woofer presents a 1 ohm mono load.
When the voice coils are wired in series with each other, the woofer presents a
4 ohm mono load. In addition, each coil may be connected to a different
amplifier channel and each channel will see a 2 ohm load.
Cone Materials: The
cone is constructed of mica-filled polypropylene. Mica adds strength and heat
resistance to polypropylene; the result is reduced distortion and improved
reliability. In addition, the cone is also very resistant to
environmental extremes.
Surround: This subwoofer uses a
tough, flexible, highly tear-resistant santoprene rubber surround. The surround
is 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 Coils: The ultra-length
voice coils allow enormous cone excursion for incredible deep bass.
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.
UniPlate Construction: The
UniPlate construction combines the backplate and extended pole piece into a
single unit to maximize magnetic efficiency and minimize alignment problems
often caused by two-piece construction.
Black Plating: The black
plating on the UniPlate and front plate provides maximum heat dissipation for
cool operation and extended voice coil life.
Bumped Back Plate: The deep
bumped back plate lets the voice coil reach maximum excursion without
bottoming-out.
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.
Rubber Magnet Boot: A black
rubber boot covers the outside edge of the magnet structure to improve the
cosmetics of the woofer and protect the magnet during installation.
Spring Posts: The nickel-plated
spring posts will accept bare wire and pin connectors.
Enclosure Compatibility: This
woofer can provide extended bass in sealed and vented enclosures (please see the
"Specifications" section for more information on the recommended
enclosures).
Specifications
Power
Handling: When the subwoofer is mounted in a sealed enclosure
that has a volume of 0.4 cu/ft, each coil can handle up to 100 watts RMS (200
watts peak). In a 1.8 cu/ft sealed enclosure, each coil can handle up to 50
watts RMS (100 watts peak). Generally, when the woofer is mounted in a vented
enclosure, its power handling decreases depending on the size of the enclosure.
In a 0.8 cu/ft vented enclosure, each coil can handle up to 37.5 watts RMS (75
watts peak). In a 1.2 cu/ft vented enclosure, each coil can handle up to 60
watts RMS (120 watts peak).
Recommended Sealed Box
Volume: The recommended sealed enclosures have the highest power
handling capability of all the recommended enclosures. When mounted in a sealed
enclosure, the woofer delivers smooth bass response with good low bass
extension.
- Compact (minimum enclosure
volume): 0.4 cu/ft; each coil can handle up to 100 watts RMS (200 watts
peak)
- SQ (maximum enclosure volume):
1.8 cu/ft; each coil can handle up to 50 watts RMS (100 watts peak)
Recommended Vented Box
Volume: The vented enclosures incorporate massive slot-loaded ports
with ultra- low air velocity and hard-hitting bass. These are not your
traditional port tubes; the slot-loaded ports are integrated into the enclosure
design.
- Compact (minimum enclosure
volume): 0.8 cu/ft; 1.5"x8" port opening; 20" port depth;
each coil can handle up to 37.5 watts RMS (75 watts peak)
- SQ (maximum enclosure volume):
1.2 cu/ft; 2"x8" port opening; 18.375" port depth; each coil
can handle up to 60 watts RMS (120 watts peak)

Corrections
Manual Corrections:
The specifications printed in the February 2001 manual are preliminary. Per
Kicker, some of the specifications have changed and the following is a list of
corrections:
- SPL: The manual lists the
sensitivity as 83dB. The correct sensitivity is 82.8dB.
- Vas: The manual lists the
Vas as 16.7 liters. The correct Vas is 16.73 liters.
