The Hartke HyDrive 112b is a compact, 12 inch. bass speaker cabinet designed for gigging bass players looking to get the most power out of their amplifier in any performance setting. Featuring Hartke's patented paper/aluminum HyDrive Speaker Technology for unmatched tone depth and clarity, this lightweight 300-watt/4-ohm cabinet is a perfect and affordable solution for any portable bass setup. HyDrive speakers features carefully crafted paper/aluminum hybrid cone drivers.

The outside paper cone delivers a smooth, even response with a deep tone, while the inner anodized aluminum cone produces smooth mids for an even tone that can be tailored for any style of music. The HyDrive 112b enclosure is constructed from high-quality plywood with extensive bracing and dado joints, making it rigid, yet lightweight for superior projection and true sonic clarity. Its black perforated steel grille adds to an already strong, sleek look. The HyDrive 112b is the perfect extension cabinet for the Hartke TX300 and TX600, or any modern lightweight bass amplifier.
