Retaining the classic enclosure, the Kickback KB12 now features Hartke's patented HyDrive Speaker Technology. With 500 watts of Class D power, this  combo is ruggedly portable and delivers serious bass tone that cuts through the mix. The Hartke KB12 HyDrive 12" speaker features a carefully crafted paper/aluminum hybrid cone driver. The hybrid makeup delivers an exceptional blend of warmth and attack that can't be attained by traditional all-paper bass speakers. The use of rare earth neodymium magnets also helps to maintain lightweight portability without sacrificing any of the legendary Hartke attack.Shape Your ToneDesigned to produce a responsive bass tone that's both tight and warm, the KB12 provides users with comprehensive tone control.
