SUB 12 Dual | 12″ Dual Voice Coil Subwoofer – Focal Performance Series
Deep Power. Dual Precision. True Focal Performance.
Designed and developed in France, the Focal SUB 12 Dual combines raw power and precision engineering to deliver an exceptional low-frequency foundation.
Its 12″ (30 cm) polypropylene cone produces tight, controlled, and distortion-free bass, while the dual voice coil design allows flexible wiring configurations — including parallel 2-Ohm operation to maximise your amplifier’s output and SPL potential.
Whether installed in a sealed or bass-reflex enclosure, the SUB 12 Dual ensures a deep, musical bass presence that enhances any in-car audio system.
Polypropylene Cone – Strength and Clarity
The SUB 12 Dual’s polypropylene cone offers an ideal combination of stiffness and lightweight responsiveness.
This material minimises distortion at high volume and maintains smooth, consistent low-end delivery — even under demanding conditions.
The result is pure, accurate, and punchy bass, perfectly aligned with Focal’s acoustic signature.
Flexible Configuration for Maximum Output
The dual voice coil (DVC) system provides installation versatility and greater control over impedance matching.
Run the sub in parallel at 2 Ohms to draw the full potential from your amplifier, or configure for higher impedance in multi-driver systems — the SUB 12 Dual adapts easily to your setup.
Enclosure Recommendations
For optimal balance between precision and power, Focal recommends:
-
Sealed box: 15 L (tight, controlled bass)
-
Bass-reflex box: 30 L (deeper, extended response)
This flexibility lets installers tune performance to suit cabin acoustics and listening preferences — from focused audiophile setups to SPL-heavy builds.
Rugged, Reliable Design
Built on a reinforced steel chassis, the SUB 12 Dual is engineered for stability and long-term durability.
It withstands vibration and high excursion effortlessly, while screw-type terminals provide a secure, low-resistance electrical connection for consistent power delivery.
Performance Series – Power You Can Feel
The Focal SUB 12 Dual brings authoritative bass and acoustic precision to any vehicle.
From subtle low-end reinforcement to ground-shaking impact, it delivers depth, balance, and musicality that embody Focal’s pursuit of excellence.
