The KICKER ST9MR4 was developed for applications that require maximum speech intelligibility, high sound pressure, and exceptional presence. With its distinctive square 9-inch diaphragm, this pro-audio midrange driver offers a larger effective diaphragm area than comparable round speakers, thereby achieving particularly high efficiency.
The robust pressed pulp cone, combined with an impregnated fabric surround, delivers a precise, dynamic midrange and remains controlled even at high volumes. Thanks to its high sensitivity, the ST9MR4 is ideal for SPL setups, show cars, and high-performance car audio systems, where vocals and instruments remain clearly audible even alongside powerful subwoofers.
The sturdy spring terminals allow for the connection of speaker cables up to 6 mm² and make installation easier
