Our take on the Kicker CompVR 05CVR84

Maximum power, wiring flexibility, and a round-shaped sub from Kicker. Put them together, and you've got the "Very Radical" CompVR. The 05CVR84 is an 8" dual voice coil sub that can handle a ton of power.

Got enough juice? Get an amp for your new sub Maximum power, wiring flexibility, and a round-shaped sub from Kicker. Put them together, and you've got the "Very Radical" CompVR. The 05CVR84 is an 8" dual voice coil sub that can handle a ton of power.

The CompVR sub features a rigid, injection-molded polymineral cone that'll stand up to the demands of your favorite low tones. Add Kicker's famous Inverted Structural Dome, and you have terrific durability and reliability.

The hyperextended, vented pole piece and back plate are molded as a single piece for outstanding heat transfer and cone travel. Perimeter venting in the non-resonant steel basket helps to keep the sub running cool. Dual 4-ohm voice coils add versatility to the way you wire your system.

Don't limit yourself to just using these subs in your car — they're built and warranted by Kicker for marine use also.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

Enclosure Compatibility


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): 0.4 cu/ft; the woofer can handle up to 200 watts RMS (100 watts per voice coil); per Kicker, the woofer will work with boxes having an internal volume as low as 0.35 cu/ft.
  • SQ (maximum enclosure volume): 1.8 cu/ft; the woofer can handle up to 140 watts RMS (70 watts per voice coil)

Recommended Vented Box Volume:

  • Compact: 0.8 cu/ft; 1.5" x 8" port opening; 20.75" port depth; the woofer can handle up to 75 watts RMS (37.5 watts per voice coil)
  • SPL/Deep Bass: 1.2 cu/ft; 2" x 8" port opening; 19.125" port depth; the woofer can handle up to 75 watts RMS (37.5 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.
