Hartke's HyDrive HD115 is a versatile bass speaker cabinet. It can fill in the bottom end of a stack, or is perfectly suited to stand alone as a single speaker. Featuring Hartke's patented paper/aluminum cone HyDrive Speaker Technology, the HD115 delivers tremendous low end with a smooth mid-frequency response, ensuring exceptional performance clarity. Handling 500 watts or power, the HD115 can take whatever you throw at it. The HyDrive HD115 is a front-ported, vented cabinet constructed from solid plywood with extensive bracing and dado joints, making it rigid, yet lightweight for superior projection and minimal energy loss. In addition, the HD115 is furnished with a black perforated steel grill, recessed steel handles, steel corners and removable casters, making it both resilient and easy to transport.
