Focal 165 SF3
165mm 3-way component kit.
The Slatefiber 165 SF3 delivers a wide, detailed soundstage. Its 165mm woofer, 65mm midrange, and Al/Mg tweeter work together across the full frequency range, from impactful bass to delicate highs, underpinned by Focal's French-made Slatefiber cone technology.
- Exclusive Slatefiber technology — cone made in France in Focal's workshops
- High power handling for long-lasting performance, even at high volume
- Optimised efficiency to limit amplification requirements
- Solid construction with rigorously selected materials for long-term reliability
- Grilles included
The second-generation Slatefiber range is designed and developed by Focal engineers to combine precision, responsiveness, and robustness. The range covers passive kits through to subwoofers, offering sound coherence across all models and easy installation throughout.
Exceptional Sonic Coherence
The Slatefiber cone is crafted in Focal's workshops using recycled carbon fibres, providing optimal rigidity and damping. Both the woofer and midrange deliver uniform, distortion-free sound — essential for a cohesive 3-way setup.
Al/Mg Tweeter & Adjustable Filtering
The aluminium/magnesium inverted dome tweeter brings clarity and finesse. Three level adjustment settings (-3dB / 0dB / +3dB) allow it to be tuned to the cabin environment. Separable crossovers enable flexible installation to suit the vehicle and system design.
Premium Construction & Perfect Integration
The 165 SF3 features an aluminium rotor design frame, butyl surround, and a 65mm midrange engineered for straightforward integration — particularly in select General Motors, Toyota, and Mercedes-Benz models. If you're looking for a 3-way component alternative at a lower price point, the Focal 165 AS3 Access Series 3-way 6.5" component speakers are also worth considering.

About the Focal 165 SF3
From our tech experts at CEN
Focal 6.5 inch three-way component speakers, with a separate tweeter, midrange and woofer.
Who it suits
Drivers building a proper front stage and happy for tweeters to be mounted separately, which usually means a professional fit.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker, and Focal drivers repay an amplifier. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: What drivers are in the 165 SF3 kit?
A: The kit has a 165mm Slatefiber woofer, a 65mm Slatefiber midrange and an aluminium/magnesium inverted dome tweeter, with separable crossovers.
Q: Which vehicles suit the 165 SF3 midrange?
A: The 65mm midrange is engineered for easy integration, particularly in select General Motors, Toyota and Mercedes-Benz models. Contact CEN to check your vehicle.
Q: Can the tweeter level be adjusted on the 165 SF3?
A: Yes. The tweeter level can be set to -3dB, 0dB or +3dB.
