SLATEFIBER MEMBRANE

Dynamic, balanced sound

Exclusive to Focal and made in France, the Slatefiber membrane is made from recycled carbon fiber and thermoplastic polymer. In their quest for perfection and as specialists in loudspeaker membranes, our engineers have chosen to use non-woven carbon fibers in this case.es in the same direction to achieve even greater rigidity, damping and lightness, the “essentials” of a good loudspeaker. Renowned for its dynamic, rich and balanced sound reproduction, this membrane has proved its worth on numerous products for the home, for professionals in recording studios, and also for listening in the car.

TWEETER IN AL/MG

Treble finesse

Membrane shape and materials are essential. For the finest treble, our engineers have patented the inverted dome tweeter, a Focal signature. The inverted dome shape offers the advantage of low directionality and a small-diameter, lightweight coil for better acceleration. As for the materials used, they combine the key points of a good loudspeaker: aluminum increases dome rigidity and reduces distortion, while the addition of magnesium provides excellent damping. The surround that connects the dome to its support uses Poron, a shape-memory material. This surround is derived from the famous Utopia Beryllium tweeter, and reduces distortion by a factor of three between 2000 Hz and 3000 Hz, where the ear is most sensitive.

Focal 165 SF 6.5″ Slatefiber Component Speakers

The Focal 165 SF is a premium 165 mm 2-way component speaker kit designed for drivers who want a serious upgrade over standard factory car audio. Built as part of Focal’s Slatefiber range, this kit combines a rigid, lightweight Slatefiber woofer cone with an Al/Mg inverted dome tweeter to deliver a more spacious, detailed and controlled listening experience.

The Slatefiber cone is made using recycled carbon fibres and thermoplastic polymer, giving the woofer the strength, damping and responsiveness needed for clean midrange and punchy mid-bass reproduction. This helps vocals sound more natural, instruments feel more defined and everyday listening become noticeably clearer and more engaging.

For high-frequency detail, the 165 SF uses Focal’s aluminium/magnesium inverted dome tweeter. This tweeter is designed to produce smooth, refined treble while maintaining excellent clarity across the cabin. With adjustable tweeter level settings of -3 dB, 0 dB and +3 dB, the sound can be tuned to suit different vehicle interiors and listener preferences.

The Focal 165 SF is also built with installation flexibility in mind. Its separable crossovers allow easier integration into a wide range of car audio systems, while the supplied grilles, screws and mounting brackets support a cleaner, more complete installation. With 80W RMS power handling, 160W maximum power, 4Ω impedance and 91 dB sensitivity, this component kit is engineered for reliable performance from a quality amplifier or upgraded car audio system.

For anyone looking to improve clarity, soundstage, detail and overall musical performance, the Focal 165 SF is a strong choice for a high-quality 6.5″ component speaker upgrade.
