KICKER’s elite KS-Series Coaxial Speakers upgrade your audio to new levels of accuracy with extended frequency response and the smoothest highs.

Potent Performance

KICKER KS-Series Speakers let you play at concert-like volume, yet maintain the smoothness and subtlety to please even the most selective ear. Internally dampened polypropylene cones and durable rubber surrounds assist the woofers in creating precise midrange and midbass, while high-quality silk-dome tweeters deliver natural, detailed highs.

With less than 2-inches of mounting depth and zero millimeters of tweeter protrusion, the KSC40 is a perfect fit in almost every vehicle on the road today. They work best with 15 to 75 watts of recommended power. See below for more details.
