New sound with throwback looks Kick crackly factory sound to the curb and step up to these Jensen JS65T 6-1/2" 3-way car speakers. Inspired by the legendary Jensen triaxial speakers of yesteryear, these new entries combine vintage looks with solid, full-range sound. They match up well to an aftermarket stereo or amp and deliver detail that schools your old, stock speakers. The speaker's polypropylene cone, PEI midrange, and tweeter serve up sweet sound but are tough enough for life in your car doors.
