Our take on the Kenwood KFC-W3003


What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Bassheads beware, a Tornado is coming your way! The distinctive look of Kenwood's pearl mica KFC-W3003 12" subwoofer tells you this speaker is something special. Three raised ridges increase the cone's rigidity and dampen unwanted resonances for improved bass clarity, creating a tornado-like appearance and a whirlwind of powerful bass.

Kenwood uses a two-layer vented voice coil, vented extended pole piece, and a vented back plate for cool-running, reliable performance, even when you subject them to a steady diet of high-volume, deep-booming tunes. Designed for use in sealed or ported enclosures, they are extremely efficient. You'll get the maximum slam from your available amplifier power.

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.


Woofers: The cone is constructed of blue 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 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 surrounds have 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.

Box Type/Volume: The woofer is designed to work best in a sealed enclosure with an internal volume of 1.5 cubic feet, or a ported box of 1.5 cubic feet (port dia 3", port length 6").
