Experience precise, high-quality sound with the MB Quart Formula FKB110 4-Inch 2-Way Coaxial Car Speakers, engineered for balanced performance and lasting reliability. This set includes 2 pairs (4 total) of full-range speakers designed to deliver clear highs, rich midrange, and impactful bass in any vehicle audio system. Each speaker handles 40 watts RMS and 80 watts peak power at 4 ohms, producing smooth, distortion-free playback with 88 dB sensitivity and a frequency response of 55 Hz to 19 kHz.

The aluminum dome tweeters provide crisp, detailed highs with excellent reliability, while the lightweight thermal-formed polypropylene cones ensure fast, accurate midrange response. Butyl rubber surrounds enhance durability and bass impact, and the high-temperature adhesive cone-to-surround connection prevents separation during high-output use. Inside, the pure copper voice coil and Kapton former efficiently manage heat, supported by an over-coil cooling system that promotes airflow through the spider for consistent performance.

Built on a heavy-gauge stamped steel frame, each speaker maintains rigidity and reduces distortion. A ferrite magnet motor generates strong magnetic force in a compact design, while the 12 dB internal crossover provides seamless transitions between the midrange and tweeter. With a mounting diameter of 3.69 inches, outside diameter of 5.39 inches, and depth of 3 inches, installation is simple using spade connectors or direct soldering. The FKB110 Series delivers professional-level sound and durability in a compact, vehicle-ready design.
