Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Extra Large Rubber Surrounds: The extra large rubber surrounds enable low frequency bass reproduction and maximum cone excursion.

Cast Aluminum Frames: Each woofer is mounted to a custom cast aluminum frame for added strength and maximum bass reproduction.

Tweeters

1" Silk Dome Tweeters: The 1" silk dome tweeters offer clean, non-fatiguing sound even under extreme high frequency demands. 

Standard Tweeter Mounting Options: The tweeters may be flush or surface mounted. Once mounted, the tweeters are adjustable and may be swiveled 20 degrees for optimum imaging.
