Our take on the Kenwood KFC-W2005 by Crutchfield's Steven Johnson
Sporting the "tornado" woofer design, Kenwood's KFC-W2005 8" subwoofer generates a whirlwind of bass with its silver pearl mica-injected polypropylene woofer. Three raised ridges increase the cone's rigidity and dampen unwanted resonances for improved bass clarity.
Kenwood uses a two-layer vented voice coil, vented extended pole piece, and bumped-back plate so this sub won't bottom out when you put it to the test. The urethane surround stands up to extremes of temperature and humidity in the car environment. Designed for use in sealed or ported enclosures, the KFC-W2005 is extremely efficient.Details:
- silver pearl mica injection-molded polypropylene woofer cone
- tornado-type raised ridge construction for improved rigidity and dampened resonance
- urethane foam surround
- extended pole piece and bumped back plate for increased cone excursion
- power range 26-250 watts RMS
- peak power 500 watts
- frequency range 30-1000 Hz
- sensitivity 91 dB SPL
- top-mount depth 3-15/16"
- sealed box volume 0.5-0.8 cubic feet
- ported box volume 0.5-0.8 cubic feet
- Recommended Q-Logic Box Type: none
- 1-year warranty

Woofers: The cone is constructed of silver Pearl Mica Injection-Molded Polypropylene. Uniform pearl mica crystals form an overlapping structure that adds strength and heat resistance to polypropylene; the result is reduced distortion and improved reliability. The woofer uses a urethane foam surround.
Tornado Woofer Cone: The cone is formed with three raised ridges around the circumference of the cone. The width of each ridge is graduated, making a tornado-like appearance. The ridges make the Tornado Cone much more rigid than conventional cones, with resonances that are more than an octave higher. Additionally, the Tornado Cone's resonances are of a more random nature than those of conventional cones, which reduces their intensity. Since these resonances are lower in amplitude and far above the woofer's useable frequency range, they are much less audible, resulting in clearer, more detailed bass sound.
Surround Material: The urethane foam surround has very high internal loss, which reduces speaker cone distortion.
Extended Pole Piece: The pole piece has been extended to provide a more linear magnetic field for woofer operation. This lowers distortion and provides the woofer with better low frequency response.
Vented Pole Piece: The vented pole piece allows air to circulate in the voice coil gap; air circulating in the voice coil gap helps dissipate heat and results in greater power handling and increased reliability.
Vented and Bumped Back Plate: The back plate has been stepped deeper to allow the woofer more room for excursion without bottoming out. This enables the speaker to be used in a smaller enclosure. Additionally, the back plate has a vent, which efficiently and quietly circulates cool air around the voice coil. By keeping the voice coil cooler, power handling is improved.
Voice Coil: The two layer vented voice coil keeps the woofer cooler and is designed for higher power handling.
Enclosure Compatibility: The woofer is designed to work best in a sealed enclosure with an internal volume of 0.6 cubic feet, or a ported box of 0.56 cubic feet (port diameter 2", port length 5").
Power Handling: Although the specifications section of the manual lists two power handling specifications, "RMS Power Handling" and "Peak Power Handling", Kenwood has established "Rated", "Maximum" and "Peak" input power ratings for this woofer. The "Rated" input power spec is equivalent to the "RMS Power Handling" spec listed in the manual, the "Maximum" input power rating is a continuous power handling specification, and the "Peak" input power rating is equal to the "Peak Power Handling" spec listed in the manual. The power ratings are as follows:
- "Rated" input power: 125 watts
- "Maximum" continuous input power: 250 watts
- "Peak" input power: 500 watts
