Focal Sub 12 Subwoofer

Focal’s Sub12 is a professional 13-inch studio subwoofer designed to deliver deep, controlled low end with exceptional precision. Combining an ultra-high-excursion W-cone driver with a powerful 600-watt BASH amplifier, it extends your monitoring system down to 28 Hz, revealing the true weight and impact of your mixes while maintaining clarity and articulation.

Engineered for modern production environments, Sub12 offers comprehensive control over level, crossover, phase and polarity, so you can integrate it seamlessly with your existing monitors and room. Robust cabinetry, optimised internal bracing and a carefully tuned front port work together to minimise noise and distortion, ensuring that what you hear is accurate and reliable, even at high SPLs.

With flexible connectivity, switchable sensitivity and practical features such as auto-standby defeat and footswitch-controlled bypass, Sub12 is equally at home in music studios, post-production suites and high-end project rooms. It is particularly well suited to partnering with Focal’s Trio6, Solo6 and Twin6 monitors, creating a full-range system that lets you confidently judge low-end balance, punch and sub-bass extension.

Housed in a reinforced enclosure with large side handles for easier two-person lifting, Sub12 is built to withstand the demands of daily studio use. From subtle low-frequency enhancement to full-on cinematic impact, it provides the headroom and control you need to make informed decisions about the bottom end of your mix.

Powerful, Precise Low-End Extension

At the heart of Sub12 is a 13-inch W-cone driver with ultra-high excursion, driven by a 600-watt class G BASH amplifier (1000 watts peak-to-peak). This combination delivers tight, impactful bass down to 28 Hz, allowing you to hear and shape the very lowest octave of your mix with confidence.

Advanced Control for Seamless Integration

Sub12 provides variable controls for low-pass frequency, high-pass frequency and phase, along with sub level adjustment and a polarity switch. This lets you fine-tune the crossover point and time alignment between the subwoofer and your main monitors, achieving a coherent, full-range sound that translates accurately.

Low Noise, Low Distortion Design

Optimised internal bass bracing and a front-firing port with internal and external flares help to reduce turbulence, port noise and unwanted resonances. The result is cleaner, more articulate low frequencies that remain controlled even at higher monitoring levels, so you can trust what you are hearing when balancing kick, bass and sub-heavy elements.

Flexible Connectivity and Studio-Friendly Features

With balanced XLR inputs for left, right and LFE, switchable +4 dBu or -10 dBV sensitivity, and a dedicated LFE output, Sub12 integrates easily into a wide range of studio setups. An auto-standby bypass switch, LED status indicators and a footswitch-controlled 2.1 bypass function give you practical, day-to-day control over how and when the sub is active.

• 13-inch W-Cone Driver with 600 W Amplifier - The ultra-high-excursion 13-inch W membrane driver, powered by a 600-watt class G BASH amplifier (1000 watts peak-to-peak), delivers powerful, controlled low end with a maximum SPL of 125 dB at 1 metre, revealing sub-bass detail that smaller systems simply cannot reproduce.
• Comprehensive Crossover and Phase Controls - Adjustable low-pass and high-pass filters, phase control, sub level and a polarity switch allow you to tailor Sub12 precisely to your room and main monitors, helping you achieve a smooth, phase-coherent transition between the sub and satellites.
• Low-Noise Front Port and Optimised Bracing - A front-firing port with carefully designed internal and external flares, combined with optimised bass bracing, reduces turbulence, mechanical noise and distortion, so the sub-bass remains tight and accurate rather than boomy or smeared.
• Studio-Ready Connectivity and Bypass Options - Balanced XLR inputs for left, right and LFE, switchable +4 dBu / -10 dBV sensitivity, LFE input and output, and a footswitch-controlled 2.1 bypass make it easy to integrate Sub12 into stereo or multichannel setups and quickly compare your mix with or without the sub.
