MB Quart FKB116S

The MB Quart FKB116S is a slim-mount 6-1/2" Formula Series 2-way coaxial car speaker built to fit shallow installation spaces without sacrificing sound quality. Each speaker handles 60 watts RMS (120 watts peak per pair) and uses a lightweight thermoformed polypropylene cone paired with a 1" aluminum dome tweeter for clear, dynamic audio. Its durable construction includes a butyl rubber surround, epoxy-reinforced natural fiber spider, ferrite magnet motor, and heavy-gauge stamped steel frame. With an integrated 6dB crossover, over-coil cooling, 4-ohm impedance, and 60–20,000 Hz frequency response, this speaker delivers efficient performance, while the included protective grilles ensure a clean, secure installation.
