In this guide
Focal's Slatefiber SF range has landed at CEN — French-built speakers with recycled carbon-fibre cones, spanning coaxials, component kits, a midrange and an 8-inch subwoofer. Highlights: the 165 SF 2-way component kit at £229.99, C 165 SF coaxials at £199.99 and the SUB 20 SF at £179.99, all in stock now.
The Slatefiber idea
The range takes its name from its cone material — non-woven recycled carbon fibres in a thermoplastic matrix, with the slate-like finish to match. It's classic Focal thinking: a stiff, light, well-damped cone delivering the lively, detailed sound the brand is known for, at a price well below its flagship ranges.
The line-up
For most doors, the choice is between the 165 SF component kit — separate tweeters for proper staging — and the simpler C 165 SF coaxials, both 6.5-inch and 80w. Going further, there's a 3-way kit, an 8-inch component option, a dedicated midrange, and the SUB 20 SF, a compact 8-inch, 200w RMS subwoofer to underpin it all.
Our take
Focal at this price point is where the brand gets seriously competitive — you're buying genuine French speaker engineering rather than a badge. If you're choosing between component and coaxial routes, our component vs coaxial guide covers the trade-offs, or ask us to match a Slatefiber setup to your car and budget.

What is Slatefiber?
