Our Product Research Team
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.
Cone Materials: The Kicker
Competition woofer consists of a vacuum formed polymineral cone with an inverted structural dome (ISD),
which remains rigid to minimize cone flex and lowers harmonic distortion. A rear
cone brace integrates into the cone with a continuous contact perimeter weld,
which offers unmatched strength and resistance to deformation under pressure.
Surround: The optimized
Polyfoam-ribbed surround allows extended cone excursion for
additional bass output and higher SPL. The surround is double-stitched to the
cone to add a mechanical fastener to the chemical adhesives. This prevents the
cone and surround from separating in the harshest conditions.
Enhanced BAM (Basket And
Motor) Assembly: The high-strength steel basket features a low-profile open
design, and provides a solid foundation for the precision-aligned motor
assembly. Perimeter venting in the BAM relieves pressure from under the spider,
supports a linear excursion, and helps dissipate heat from the voice coil and
Voice Coils: The
ultra-strength voice coil sustains enormous cone excursion and provides extra
heat dissipation. The high-temperature Polyimide Film voice coil
former improves sonic and conductive properties, and prevents thermal-electrical
woofer features a two-piece vented hyper-extended blackened
pole piece and backplate. This unique design provides the following benefits:
- Optimizes heat transfer
efficiency for cooler operation and maximum power handling ability.
- Eliminates erratic magnetic flux
from the voice coil gap.
- Releases pressure under the
suspension for uniform cone movement and responsive low bass.
- Prevents the voice coil from
bottoming out and corresponding damage.
Tinsel Leads: The woofer
features high-power tinsel lead wires to resist breakage and
power-robbing resistance losses due to the common use of "insufficient gauge"
Speaker Terminals: The
spring loaded, nickel-plated terminals provide solid connections for bare wire
up to 10 gauge.
Free Air Applications: Kicker
Competition subwoofers can be very effective in an infinite-baffle (free-air)
installation. You may need to reinforce the rear deck of your vehicle to support
the weight of the subwoofer (3/4" MDF is recommended).
Recommended Sealed Box
- Compact (minimum enclosure
volume): 1.25 cu/ft; the woofer can handle up to 250 watts RMS
SQ (maximum enclosure volume):
3.5 cu/ft; the woofer can handle up to 150 watts RMS
Recommended Vented Box
- Compact: 1.75 cu/ft; 1.5" x 10.5" port opening; 14.5"
port depth; the woofer can handle up to 150 watts RMS
SPL/Deep Bass: 2.25 cu/ft; 1.5" x 10.5" port opening;
13.25" port depth; the woofer can handle up to 150 watts RMS
Note: The power handling specifications listed with
the vented enclosure recommendations apply only when a 25Hz, 24dB/octave
subsonic filter (sold separately) is used with this woofer. If a
subsonic filter is not used, power handling may decrease, excessive port
noise can occur, and the life of the woofer may be shortened.
