Enclosure Compatibility
Features
Marine Ready: This woofer is
made with a powder coated, weather resistant basket and stainless steel
hardware, so it can be used in marine and mobile applications.
Dual Voice Coils: For increased
system flexibility, the woofer has two 4 ohm voice coils. When the voice coils
are wired in parallel, the woofer presents a 2 ohm load. When the voice coils
are wired in series, the woofer presents an 8 ohm load. In addition, each coil
may be connected to a different amplifier channel and each channel will see a 4
ohm load.
Cone Materials: The Kicker Comp
VR woofer consists of a unique one-piece, aluminum vapor-deposit material that
moves as a lightweight piston, exhibiting power and control. This
injection-molded polymineral cone features 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 Santoprene 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 structure.
Voice Coils: The dual
ultra-strength voice coils sustain enormous cone excursion and provide flexible
impedance matching options. The high-temperature Polyimide Film voice coil
former improves sonic and conductive properties, and prevents thermal-electrical
meltdown.
UniPlate Construction: The
woofer features a one-piece UniPlate construction with a vented hyper-extended
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 sleeved high-power tinsel lead wires to resist breakage and
power-robbing resistance losses. The lead wires are terminated with
polymer-based strain relieving mechanical fasteners.
Speaker Terminals: The
spring loaded, nickel-plated terminals provide solid connections with medium to
heavy gauge speaker
wire.
Break-in Period:
Due to the complex nature of Kicker Comp VR speakers, they require a
break-in period in order to produce optimum low-bass response. The
high-performance suspension system makes the speaker very stiff
"out-of-the-box". Approximately 2 weeks of daily playing will allow
the suspension to break-in and reach its optimum equilibrium. A
"broken-in" subwoofer will exhibit stronger bass performance, smoother
response, and greater low-bass extension.
Enclosure
Compatibility
Power Handling: The
power handling specifications differ according to the type and size of the
enclosure. The power handling specifications assume that both voice coils are in
use. Note: Both voice coils in a dual voice coil speaker should always be
connected.
Recommended Sealed Box
Volume:
- Compact (minimum enclosure
volume): 1.0 cu/ft; the woofer can handle up to 400 watts RMS (200 watts
per voice coil)
- SQ (maximum enclosure volume):
4.6 cu/ft; the woofer can handle up to 300 watts RMS (150 watts per voice
coil)
Recommended Vented Box
Volume:
- Compact: 1.75 cu/ft;
2.5" x 12.5" port opening; 20" port depth; the woofer can
handle up to 300 watts RMS (150 watts per voice coil)
-
SPL/Deep Bass: 2.25 cu/ft; 3" x
12.5" port opening; 20.5" port depth; the woofer can handle up to 300 watts RMS (150 watts per voice coil)
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.
