The HyDrive HD210 is the next step in speaker evolution. Compact and lightweight, this dual 10" bass cabinet is perfect for the working bassist. On its own or as part of a stack, the 500-watt HD210 delivers a full sound from Hartke's patented HyDrive HD paper/aluminum hybrid cone speakers. HyDrive Evolved The HyDrive HD speaker design features a two-piece composite cone that combines a straight, anodized aluminum inner cone with a curved, Kevlar?-filled paper outer cone to deliver clean, clear output with extremely smooth response. The double-roll curvilinear surround limits driver excursion while providing smooth midrange response. The result is a clean, full tone with the clear fundamentals of each note, as well as natural harmonics to further define your sound. In addition, a round-wire voice coil and vented former design have been incorporated to provide a nice low-end zing and optimize power handling. Built to Perform The HyDrive HD210 is a sealed cabinet constructed of solid plywood with extensive bracing and dado joints, making it rigid yet lightweight for superior projection and minimal energy loss. In addition, the HD210 features a black perforated steel grille, recessed steel handle and steel corners, making it both durable and easy to transport.
