Product description

KICKER®’s KS-Series Component Systems are stunningly accurate upgrades with extraordinary mounting flexibility.

Center Stage

  • High power handling
  • Silk-dome tweeters for a smooth sound
  • Polypropylene woofer and tough rubber surrounds
  • Thin-mount design easily fits behind factory grilles
  • Four tweeter mounting options
  • Articulating tweeter pod included
  • Smaller crossover makes mounting even easier
  • Grilles included

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 bass, while high-quality silk-dome tweeters deliver natural, detailed highs.

Experience your music as a component system with separate tweeters, or as a high-end coaxial system. The woofer's removable bullet-style phase plug is replaced with a special adapter, allowing the 25 millimeter, silk-dome tweeters to rotate and tilt. You get more system design options and superior off-axis performance. They work best with 15 to 100 watts of recommended power. See below for more details.
