Hartke makes a wide range of amplifiers and speakers for instrument amplification. Founded in the late 1970s by Larry Hartke and Ron Lorman, they created the first aluminium cone drivers that later became the HyDrive series. As their products gained popularity in the clubs and groups around New York, Hartke became more established, and developed an entire range of cabinets and speakers that have been played on stages around the world by the likes of Thin Lizzy, Megadeath and Anthrax. Today Hartke is one of the largest manufacturers of bass amplification.
