Product Description

KS Speakers

KICKER KS-Series Speakers let you play at concert-like volume, yet maintain the smoothness and subtlety to please even the most selective ear.

KS Speakers

The high-performance woofers utilize internally dampened polypropylene cones and tough rubber surrounds for outstanding midrange detail and pounding bass!

Coaxials

Completely redesigned for 2020 with new cones, voice coils and crossovers, KS-Series Coaxial Speakers are a serious upgrade from your factory sound. Featuring zero (or minimal) tweeter protrusion, you get a perfect fit in almost every vehicle on the road today, without modifications.

Convert and Customize

Experience your music as a component system with separate tweeters, or as a high-end coaxial system. In addition to the coaxial options, you can surface mount the tweeter, angle it in a custom direction, or use the articulating tweeter pod to get perfect imaging and soundstage.
