The MB Quart FKB113 is a 5-1/4" Formula Series 2-way coaxial car speaker designed for clean, balanced sound in a wide range of vehicles. Each speaker handles 45 watts RMS (90 watts peak per pair) and features a lightweight thermoformed polypropylene cone with a 1" aluminum dome tweeter for crisp, detailed highs. Built to last, it incorporates a butyl rubber surround, epoxy-reinforced natural fiber spider, ferrite magnet motor, and a heavy-gauge stamped steel frame. An integrated 6dB crossover and over-coil cooling provide performance efficiency, while a 4-ohm impedance, 60–20,000 Hz frequency response, and 88 dB sensitivity ensure strong audio output. Protective speaker grilles are included for a complete and durable installation.
