Focal Sub One High-efficiency Professional Subwoofer

For producers and sound engineers with higher demands in the sub-bass, Focal offers Sub One, a subwoofer that delivers power of 200 Watt RMS. Thanks to its precision and very low distortion, this long-excursion, high-efficiency subwoofer ensures ideal coupling with the Alpha Evo line but also the Shape line of monitors.

The speaker drivers boast an exclusive double-skinned Slatefiber cone: the two cones affixed against each other offer even greater rigidity, ideal for a subwoofer. Finally, with its large vents located on the front panel, Sub One is very easily and discreetly positioned along a wall or under a desktop as it takes up less depth.

Sub One is a subwoofer composed of two 8" Slate fiber cone woofers, manufactured in France by Focal. Designed with a focus on its width and front vents, Sub One integrates easily into a room, along a wall or under a desk.

For a powerful and precise sub-bass, Sub One is the perfect tool to work with in the studio. Its exclusive double-skinned Slate fiber speaker drivers offer even more rigidity, an essential characteristic for a subwoofer. With its 200-watt RMS power and shallow depth, this long-excursion, high-efficiency subwoofer ensures perfect coupling with the Focal Alpha Evo and Shape lines.
