Hartke KB12 Kickback 12" 500W Bass Combo Amplifier — High-Power Punch in a Portable Tilt-Back Design
Deliver crushing bass response and sharp transient attack with the Hartke KB12 Kickback Bass Combo Amplifier. Powered by an efficient 500-Watt Peak (250-Watt RMS) Class D amplifier and a 12" HyDrive paper/aluminum hybrid cone speaker, the KB12 produces a warm, round low-end paired with tight, punchy midrange projection.
Featuring Hartke's iconic dual-position cabinet design, the KB12 can sit upright as a traditional combo or tilt back at a 45-degree angle to serve as a personal stage monitor. Weighing just 28 lbs thanks to its rare-earth neodymium speaker magnet and lightweight plywood enclosure, it is designed for gigging bassists, rehearsals, and studio tracking.
Key Features
- HyDrive Speaker Technology: Patented 12" hybrid cone combines an inner aluminum cone for fast attack with an outer paper cone for smooth warmth.
