Focal C 165 SF 6.5″ Slatefiber Coaxial Speakers

Focal C 165 SF 6.5″ Slatefiber Coaxial Speakers The Focal C 165 SF is a premium 165 mm 2-way coaxial speaker kit designed for drivers who want a serious sound upgrade without moving to a full component speaker installation. Built as part of Focal’s Slatefiber range, this coaxial kit combines a Slatefiber woofer cone with an aluminium/magnesium inverted dome tweeter to deliver clear, powerful and balanced sound reproduction. The Slatefiber cone is made in France using recycled carbon fibres and thermoplastic polymer, giving the speaker the rigidity, lightness and damping needed for accurate audio performance. This helps the Focal C 165 SF reproduce clean midrange detail, controlled mid-bass and natural vocal clarity, making everyday listening more precise and enjoyable. Its integrated Al/Mg inverted dome tweeter delivers refined high-frequency detail with wide dispersion, helping create a more open and detailed sound inside the vehicle. Because the tweeter is built into the coaxial design, the C 165 SF is a practical option for many factory speaker locations where simple integration and improved performance are both important. With 80W RMS power handling, 160W maximum power, 4Ω impedance and 91 dB sensitivity, the Focal C 165 SF is engineered to perform well with a quality amplifier or upgraded car audio system. The butyl surround, ferrite motor and durable aluminium chassis support long-term reliability, while the supplied grilles, screws and mounting brackets make installation easier across a wide range of vehicles. For anyone looking to upgrade factory car speakers with a clean, dynamic and premium coaxial solution, the Focal C 165 SF is an excellent choice from the Slatefiber speaker range.
