The exceptional KS-Series of speakers utilizes massive motor structures that provide ultimate power handling and high efficiency for louder, clearer sound. KICKER's exclusive Extended Voice Coil (EVC) technology allows for high excursion and superior bass response, while the tapered polymer cones with tough Santoprene? surrounds deliver smooth midrange frequencies for the most accurate musical reproduction. The calibrated Kaladex-dome tweeters (half- or three-quarter-inch) with stout neodymium magnets and phase alignment reveal every detail, adding to the live-performance realism provided by the KS-Series of mobile speakers. With 10 flexible woofer sizes, the KS-Series ensures a perfect fit in any car, starting from the capable 3-inch coaxials to the beefy 6x9s boasting 1-inch tweeters. The 6x9-inch KS693 3-Way Speaker System mixes in additional 1-inch midrange drivers with three-quarter-inch tweeters.
