Description
Focal 165 SF 6.5″ Slatefiber Component Speakers
The Focal 165 SF is a premium 165 mm 2-way component speaker system designed for drivers who want a significant upgrade over standard factory audio. As part of Focal’s Slatefiber range, this kit delivers improved clarity, soundstage depth, and overall musical realism for a more engaging in-car listening experience.

Advanced Slatefiber Woofer Technology
Focal engineers the woofer using Slatefiber cone technology, which combines recycled carbon fibres with a thermoplastic polymer. As a result, the cone achieves an ideal balance of rigidity, damping, and responsiveness.
This design allows the speaker to:
- Deliver clean and controlled midrange performance
- Produce tight, punchy mid-bass response
- Improve vocal clarity and natural instrument reproduction
In addition, this construction enhances overall sound precision, making everyday listening noticeably more detailed and refined.

Refined High-Frequency Performance
Focal equips the 165 SF with an aluminium/magnesium inverted dome tweeter to reproduce high-frequency detail with accuracy and smoothness.
The tweeter delivers:
- Clear and refined treble response
- Excellent dispersion across the cabin
- Improved spatial imaging and detail retrieval
Furthermore, you can fine-tune the sound output using adjustable tweeter level settings (-3 dB, 0 dB, +3 dB), allowing optimisation based on vehicle acoustics and personal preference.
Flexible Installation & Integration
Focal designs the 165 SF for easy integration into a wide range of vehicle audio systems.
- You can separate the crossover, tweeter, and woofer components for flexible installation options
- The kit includes grilles, screws, and mounting hardware for a complete installation solution
- Standard 4Ω impedance ensures compatibility with most amplifiers and head unit upgrades
In addition, the system supports straightforward upgrades into both OEM replacement and custom audio builds.

Power Handling & Performance
The Focal 165SF is engineered for reliable and consistent performance:
- 80W RMS power handling
- 160W maximum power
- 91 dB sensitivity
As a result, the system performs efficiently with quality amplification and maintains clarity and control even at higher volumes.
Premium 6.5″ Speaker Upgrade
Whether you replace factory speakers or build a high-performance audio system, the Focal 165 SF Slatefiber Component Speakers deliver improved clarity, a wider soundstage, and enhanced musical detail.
Ultimately, this kit provides a well-balanced, high-fidelity upgrade for any driver seeking premium in-car audio performance.
