About the Focal 165 SF
From our tech experts at CEN
The Focal Slatefiber 165 SF is a 6.5 inch 2-way component speaker kit rated at 80W RMS. Its woofer uses a French-made Slatefiber cone constructed from recycled carbon fibres, paired with an aluminium/magnesium inverted dome tweeter. Frequency response is 60Hz to 21kHz at a nominal 4 ohm impedance.
Who it suits
This kit suits drivers replacing factory speakers who want honest, detailed audio with strong dynamics. The 91dB sensitivity means it will work from head unit power, though an external amplifier makes the most of the 80W RMS rating. For a step down, consider the Focal 165 AS Access component kit.
Our tech experts advise
Separable crossovers allow flexible integration with your existing wiring. The tweeter level adjusts at -3dB, 0dB or +3dB to suit your cabin acoustics, with surface, factory-location and angled mounting options available. Grilles, brackets and screws are included. Fitting is priced per vehicle — see our Nottingham car audio installation page for details.

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: Can the tweeter level be adjusted on the 165 SF?
A: Yes. The tweeter level can be set to -3dB, 0dB or +3dB to suit your cabin.
Q: How can the 165 SF tweeters be mounted?
A: The tweeters can be surface mounted, fitted in the factory location or installed with the angled support.
Q: What's in the box with the Slatefiber 165 SF?
A: The Slatefiber 165 SF kit, screws, mounting brackets and grilles.
