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.

Our take on the Kenwood Excelon XR-W10F

by Jo Greene

The Kenwood Excelon XR-W10F 10" subwoofer produces serious bass output in the hard-to-fit areas of your compact car or truck. This shallow-mount sub measures just over 3" deep, so you can really get creative with your installation.

Big cone, big bass
The extremely light glass-fiber cone is 25% larger than last year's model, employing a honeycomb pattern that delivers quick response in demanding conditions without flexing. More cone surface area means this sub can move more air, so this design gives you powerful, accurate bass out of an extremely compact speaker. It's like getting an 11" sub in a 10" frame.

Innovative design
The sturdy butyl rubber surround helps to control the cone, so this woofer can rock hard without losing its punch. The cast aluminum basket offers a unique design that vents air out from the back and all sides of the subwoofer for exceptional heat dissipation. Pair this sub with the right amp and enclosure, and you'll get some powerful bass without losing too much space in your vehicle.

Features

Flat Subwoofer: The Kenwood Excelon flat subwoofer design is approximately 40% slimmer (less deep) than a standard subwoofer. This makes it ideal for installation in tight spaces, such as behind or under the seat of a pickup truck.

Carbon-Glass Fiber Cone: The carbon-glass fiber cone uses a honeycomb design which is simultaneously efficient and durable.

Rubber Surround: The woofer features a smooth linear rubber surround for added durability and increased excursion resulting in exceptional deep bass response.

Heat Transfer System: The XR-W10F features a dual ventilation system designed specifically for its slim-design.

Aluminum-Cast Basket: The woofer is housed in a die-cast aluminum basket for increased rigidity and long-lasting reliability.

Spring Terminals: The spring post terminals on one side of the woofer connect to your amplifier's wiring. The posts will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge.

Enclosure: Kenwood recommends a sealed box with an internal volume of 0.6 ft³.
