Slatefiber 200mm (8') Subwoofer


The second generation Slatefiber range relies on its exclusive technology, designed and developed by Focal engineers to combine precision, responsiveness and robustness. Every car journey becomes a clear, dynamic listening experience, true to Focal’s signature sound. From passive kits to the subwoofers, the range offers perfect sound coherence across its models, as well as a bold design. The Slatefiber solutions are characterised by their performance, versatility and easy installation.


The Focal SUB 20 SF is a premium 200 mm passive car subwoofer designed for drivers who want stronger bass performance without needing an oversized subwoofer installation. Built as part of Focal’s Slatefiber range, it combines a compact 8″ format with powerful low-frequency output, making it ideal for car audio systems where space, control and sound quality all matter.

At the heart of the SUB 20 SF is Focal’s exclusive Slatefiber cone, made from recycled carbon fibres and thermoplastic polymer. This cone technology is engineered for rigidity, speed and precise damping, helping the subwoofer produce bass that feels deep, dynamic and controlled rather than loose or overpowering. The result is stronger impact, cleaner low-frequency response and a more complete listening experience across a wide range of music styles.

The SUB 20 SF is built for reliable performance, with a ferrite motor providing stability at high excursion and a butyl surround helping maintain control during demanding playback. Its aluminium rotor design frame adds strength and a premium visual finish, while the push terminal block supports quick and secure installation.

With 200W RMS power handling, 400W maximum power, 4Ω impedance and 87 dB sensitivity, the Focal SUB 20 SF is designed to integrate into a wide range of upgraded car audio systems. Its 90 mm mounting depth also makes it a practical choice for custom enclosures and vehicle-specific bass upgrades where a larger subwoofer may not be suitable.

For anyone wanting compact bass with genuine Focal sound quality, the Focal SUB 20 SF is an excellent Slatefiber subwoofer solution that delivers depth, control and impact.
