With the exceptional tone of a HyDrive speaker housed in a durable, highly portable enclosure, Hartke's HD50 Bass Combo is able to perform at levels far beyond ordinary bass combos. The HD50 is a compact combo featuring a 50-watt amp and a 10 inch custom-designed HyDrive Series speaker. Hartke HyDrive transducers are a radical change and improvement in bass speaker technology. The unique hybrid cone speaker is constructed using an outside paper cone, producing deep and warm low frequencies, and an inside aluminum cone which produces mids and cut, yet are still sweet.
