Otherwise, both speaker models sport similar features, including a Multi-OEM Adapter plate and Flexfit design.
The P1S652's 2-way array features a PEI dome tweeter and a mineral-filled, polypropylene injection molded cone which produce a frequency response of 65Hz - 22kHz for fairly well-rounded audio performance. Its included Multi-OEM Adapter plate allows the P1S652 to be more easily integrated into most car speaker opening sizes, including 5"x7" and 6"x9" openings. Additionally, the P1S652's Flexfit design features elongated screw slots rather than holes for easier integration into most speaker mounts.
