The Focal Sub One is a high-efficiency active subwoofer designed to bring precision and neutrality to professional monitoring setups. Engineered with a focus on acoustic integration and sonic transparency, it delivers 200W RMS of power through a dual-woofer design.
Whether utilized for music production, post-production, or broadcasting, the Sub One ensures that low frequencies are represented with accuracy, allowing engineers and producers to make critical mixing decisions with confidence.
Precise Low-End Punch
At the core of the Sub One are two 8-inch woofers featuring Focal’s exclusive Slatefiber technology. Manufactured in France using recycled carbon fibers, these cones are characterized by their exceptional rigidity and damping properties. This design choice allows the subwoofer to render bass frequencies with impressive dynamics and micro-details while maintaining very low distortion levels, ensuring that the sound remains neutral rather than colored.
Slatefiber Technology: The double-skinned Slatefiber cones provide the necessary rigidity to produce a precise, articulate bass response.
200W RMS Power: Powered by Class D amplification, the Sub One delivers consistent, high-efficiency output across its 32Hz to 120Hz frequency range.
Low Distortion: The driver construction and amplification are tuned to maintain sonic clarity, even at higher sound pressure levels.
Designed for Seamless Integration
Many studio subwoofers are difficult to place due to rear-porting or bulky dimensions, but the Sub One is built to fit discreetly into modern production environments. The cabinet features a shallow depth and large front-facing vents, which allows for stable tonal balance even when the unit is positioned directly against a wall or under a desk. This design flexibility ensures optimal performance regardless of room constraints.
Front-Facing Vents: Large front ports eliminate the acoustic issues common with rear-ported subs when placed near walls.
Space-Saving Profile: The cabinet’s depth is minimized to allow for easy integration under workstations or in smaller control rooms.
Acoustic Neutrality: The cabinet construction is designed to remain inert, preventing unwanted resonance from interfering with the audio signal.
Comprehensive Control and Management
To function effectively as part of a 2.1 or multichannel system, a subwoofer must be perfectly aligned with the main monitors. The Sub One provides a suite of adjustable controls, including a fully adjustable low-pass crossover, volume, phase adjustment, and polarity inversion. Additionally, the unit features a dedicated footswitch input that allows users to mute the subwoofer and high-pass filters, enabling quick A/B comparisons between the full-range system and the monitors alone.
Adjustable Crossover: Features a variable low-pass filter and selectable high-pass settings (60Hz or 90Hz) for optimal satellite integration.
Footswitch Bypass: A dedicated input allows for hands-free muting of the sub, essential for checking the mix on limited-bandwidth systems.
Phase Alignment: Includes both a continuous phase adjustment knob and a polarity switch to ensure perfect time alignment with your main speakers.
Build Your Sound on Solid Ground
The Focal Sub One offers a professional solution for those seeking to extend the bandwidth of their monitoring system without introducing artifacts or placement headaches. By combining innovative driver materials with a practical form factor and versatile controls, it serves as a reliable foundation for any critical listening environment.
