The HyDrive Design
The KB12's 12" HyDrive speaker features Hartke’s patented paper/aluminum hybrid cone technology for an exceptional blend of warmth and transient attack that can't be attained by traditional all-paper bass speakers. The use of rare earth neodymium magnets provides lightweight portability without sacrificing any of the legendary Hartke tone.

Shape Your Tone
Designed to produce a responsive bass tone that’s both tight and warm, the KB12 preamp provides users with comprehensive tone control. Quickly dial in tone adjustments with the perfectly tuned 3-band EQ and Hartke’s exclusive variable “Shape” circuit. When activated, the “Shape” knob varies the frequency range of a unique, fixed EQ curve that generates a dramatic variety of tone, color, and harmonics.
Kickback Versatility

In addition to sitting upright, the KB12 can be placed in the "kickback" position for better on-stage monitoring and clarity. The KB12 also features a headphone output for practice and a balanced XLR direct output to the mixer for live performance. With all new high power amps and HyDrive speakers, the Hartke KB12, and its big brother the KB15, have re-defined the standard for professional bass combos.
