Focal Sub One

The Focal Sub One is a studio subwoofer equipped with two eight-inch Slatefiber cones, delivering transparent and natural low-end sound. It’s an essential tool for mixing engineers, featuring a custom-designed Class-D amplifier that provides 200W RMS of clean, consistent power. The French-made Slatefiber cones cover a wide frequency range from 32Hz to 120Hz, offering greater rigidity than traditional materials. This ensures fantastic dynamics and minimal distortion, even at high volumes.

Designed with a sleek, compact profile and front-mounted bass ports, the Sub One is ideal for smaller studios, allowing for optimal placement without performance issues, even against walls.

The Sub One is perfect for mixing engineers and producers, offering numerous connectivity options and customizable crossovers for seamless integration with any speaker system. Derived from one of the world's best-selling studio monitors, it embodies 40 years of French craftsmanship, delivering one of the most neutral and accurate subwoofers available.

The Sub One’s two eight-inch Slatefiber cones, specifically developed for Focal, reach depths of 32Hz with exceptional clarity, ensuring an unrivaled low-end monitoring experience. Paired with a custom Class-D amplifier, it provides 200W of pristine, consistent power, free from distracting distortion for smooth, transparent low-end mixing.

Featuring a wide range of user controls, the Sub One allows you to tailor your listening experience. An adjustable high-pass crossover can be set to 60 or 90Hz, catering to different genres and ensuring balanced, neutral sound. An adjustable low-pass crossover frequency lets you determine where your main monitors cut off the low-end before filtering into the subwoofer, ensuring the most natural crossover.

Additional controls include mono summing to simulate portable speaker playback, as well as phase and polarity switches, offering flexibility in your monitoring setup.

The Focal Sub One integrates easily into any studio with various inputs and outputs, including TRS, balanced XLR, and dedicated LFE connectivity. Its compact design and front-mounted bass ports allow for placement near walls without compromising performance, making it ideal for space-constrained studios.

Constructed from reinforced MDF with internal bracing, the Sub One minimizes internal resonance, preventing distorted low-end sounds. This design ensures clean, transparent audio at any volume, making it perfect for precise music mixing.
