Revitalizing the revolutionary HyDrive design, Hartke's HyDrive HD Series Bass Cabinets are the next step in speaker evolution. An improved version of Hartke's patented paper/aluminum HyDrive Speaker Technology delivers unmatched tone depth and clarity, while rugged, yet lightweight plywood construction and huge power handling solidifies these cabinets as the right choice for modern demanding bass players. HyDrive speakers feature carefully crafted paper/aluminum hybrid cone drivers. The hybrid makeup delivers an exceptional blend of warmth and attack that can't be attained by traditional all-paper bass speakers. The outside curved Kevlar®-loaded paper cone delivers smooth, even response with a deep tone, while the inner straight anodized aluminum cone produces highly accurate, distortion-free output. The HyDrive HD cabinets provide depth and clarity that is unrivaled. The new double-roll curvilinear surround limits the drivers from over excursion, while providing a smooth midband response. The result is a clean, full tone with the clear fundamentals of each note, as well as natural overtones to further define your sound. New optimized ferrite magnet assembly and steel chassis design deliver a maximum power to weight ratio to each of these HyDrive HD cabinets. In addition, the enclosures themselves are constructed from high-quality plywood with extensive bracing and dado joints, making them rigid, yet lightweight for superior projection and true sonic clarity. Their black perforated steel grilles add to their already strong, sleek look.
