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 SF3 6.5″ Slatefiber 3-Way Component Speakers

The Focal 165 SF3 is a premium 165 mm 3-way component speaker kit designed for drivers who want a more complete, detailed and immersive car audio upgrade. As part of Focal’s Slatefiber range, this system combines a 165 mm woofer, dedicated 65 mm midrange driver and aluminium/magnesium inverted dome tweeter to deliver a wide soundstage with improved clarity across the full frequency range.

The Slatefiber cone technology is engineered for rigidity, lightness and damping, helping the woofer and midrange reproduce sound with excellent balance and control. This allows the 165 SF3 to deliver punchy bass, clean midrange detail and natural vocal performance, making it a strong choice for listeners who want more than a basic speaker replacement.

Unlike a standard 2-way component kit, the 3-way design separates bass, midrange and treble reproduction across dedicated drivers. This improves staging, definition and tonal accuracy, especially in vehicles where careful speaker placement and system tuning are important. The 65 mm midrange driver helps bring vocals and instruments forward, while the Al/Mg inverted dome tweeter adds smooth, precise and refined high-frequency detail.

The Focal 165 SF3 also includes separable crossovers with adjustable tweeter level settings of -3 dB, 0 dB and +3 dB, allowing installers to fine-tune the system to suit the vehicle cabin and listener preference. With 80W RMS power handling, 160W maximum power, 4Ω impedance and 91 dB sensitivity, this kit is built for high-quality amplified car audio systems.

For a premium front-stage upgrade with stronger imaging, clearer vocals and more accurate sound reproduction, the Focal 165 SF3 is an excellent 3-way Slatefiber speaker solution.
