SUB 12 Slim | 12″ Shallow-Mount Subwoofer – Focal Performance Series
Deep Power. Compact Design. Pure Focal Performance.
The Focal SUB 12 Slim redefines what a compact subwoofer can do.
With its 12″ (30 cm) polypropylene cone, this shallow-mount sub delivers remarkably deep, tight bass while maintaining a slim, space-saving profile ideal for restricted installation zones — such as boot side panels or behind seat cavities.
Engineered and developed in France, the SUB 12 Slim channels Focal’s legendary acoustic precision into a high-efficiency, low-depth chassis, perfect for modern vehicles demanding both form and function.
Shallow Depth, Maximum Bass
Despite its compact size, the SUB 12 Slim produces powerful, impactful low-end response that enhances any OEM or aftermarket sound system.
Its single voice coil design simplifies installation and wiring, providing reliable impedance control and consistent output even at higher volumes.
Whether paired with a factory head unit or an external amplifier, this subwoofer ensures clean, distortion-free performance across a wide frequency range.
Polypropylene Cone – Strength and Control
Crafted from high-rigidity polypropylene, the cone minimises distortion and flex even under extreme excursion.
This precision-engineered diaphragm ensures tight transient response, clean bass notes, and long-term reliability — making it ideal for demanding automotive environments.
The result is deep, controlled, and accurate bass, true to Focal’s commitment to acoustic excellence.
Compact Integration
With its very shallow mounting depth, the SUB 12 Slim fits easily into confined spaces without sacrificing performance.
Perfect for sealed enclosures from 15L, it offers smooth, natural bass extension while maintaining high power handling and impressive thermal stability.
Rugged, Reliable Build
A reinforced steel chassis provides exceptional rigidity and vibration resistance, while screw-type terminals ensure quick, secure, and low-loss electrical connections.
Every detail has been engineered to deliver long-term reliability and acoustic integrity, even in compact installations.
Performance Series – Compact Power, Refined Sound
The Focal SUB 12 Slim offers the perfect blend of compact form, high performance, and pure bass authority.
It’s designed for drivers who want tight, musical low frequencies without giving up valuable cabin space.
