Power Meets Precision in the Focal SUB 20 SF

The Focal SUB 20 SF is built to bring your music to life with deep, controlled bass that you can actually feel. This 200 mm subwoofer doesn’t just add low-end—it reshapes the entire listening experience in your vehicle. Thanks to its advanced Slatefiber cone, every beat hits with clarity, energy, and control. Want bass that stays tight even when you turn it up? That’s exactly what this delivers.

Slatefiber Cone: The Core of the Sound

At the heart of the Focal SUB 20 SF is its exclusive Slatefiber membrane, made from non-woven recycled carbon fibers and thermoplastic polymer. Think of it like a perfectly tuned drum—light, rigid, and responsive. The result? Bass that’s dynamic, balanced, and free from distortion, even during long listening sessions. This technology, developed and made in France, is engineered for precision and consistency across every note.

Built for Power and Control

This subwoofer is designed to handle serious output without losing composure. With 200W RMS and up to 400W maximum power, it delivers strong, impactful bass while maintaining control. The ferrite magnet keeps performance stable during high excursion, while the butyl surround ensures durability and accurate diaphragm movement. It’s like having a firm grip on every bass note—nothing gets loose or muddy.

Durable Design That Lasts

The aluminium rotor-style chassis isn’t just about looks—it adds strength and long-term reliability. Combined with carefully selected materials, the Focal SUB 20 SF is built to perform consistently over time. Whether you’re pushing it hard or cruising at moderate levels, it holds up without compromise.

Efficient and System-Friendly

Not every system needs massive power to sound good, and this subwoofer proves it. Its optimized efficiency means you don’t need excessive amplification to get strong performance. That makes it a flexible choice for a wide range of car audio setups. Simple push terminal connections and an included grille make it practical and ready to go right out of the box.

Compact Size, Serious Output

With a mounting depth of just 90 mm and a cut-out diameter of 200 mm, the Focal SUB 20 SF fits into tighter spaces without sacrificing output. It’s compact, but don’t let that fool you—this subwoofer delivers bass that feels anything but small.
