Overview: The Kicker 07DC122 Dual Subwoofer Enclosure combines two 12"
Kicker Competition subwoofers with a computer-modeled and human fine-tuned
vented enclosure to offer a high-level of bass performance. The Kicker Dual
Subwoofer Enclosure is designed for use in SUV and sedan type vehicles.
Vented Enclosure: The vented enclosure has been computer modeled and
human fine-tuned for perfectly matched bass performance. The vented enclosure
features a 6.875" side firing port. At some frequencies most of the bass is
output from the vent so it needs at least four inches clearance to ensure
adequate air flow. The vented enclosure uses spring loaded, nickel-plated
terminals which provide solid connection for speaker wire up to 8 gauge. Single
banana plugs and pin connectors will also fit. The terminals are on the left
side of the enclosure, beside the port. The vented enclosure's outer exterior is
lined with rich, thick carpeting in charcoal gray and black. The vented
enclosure comes supplied with four mounting brackets and the necessary hardware
to secure the subwoofer box in your vehicle.
Dual 12" Comp Woofers: The Kicker 07DC122 Dual Subwoofer Vented
Enclosure features two pre-loaded Kicker Competition 12-inch, 4-ohm subwoofers
(07C124) wired in parallel for a 2-ohm load at the enclosure's speaker terminal.
- 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
- 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 motor
- 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 meltdown.
- Construction: The 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" lead wires.
- Speaker Terminals: The spring loaded, nickel-plated
terminals provide solid connections for bare wire up to 10 gauge.
