All About HyDrive. HyDrive transducers represent a revolutionary improvement in bass speaker technology and a major leap forward, fusing paper and aluminum in a roadworthy speaker design that is more robust and efficient than anything available. With Hartke's HyDrive series, you get the best of both worlds: the warm tone of traditional paper cones and the clear, punchy attack of aluminum. HyDrive's patented Hybrid Cone Technology produces a speaker that uses an outside paper cone to push a warm, deep low frequency and an inner aluminum cone that produces mids and highs that cut, yet still remain sweet.
