Sub One is a subwoofer composed of two 8" (20cm) Slatefiber cone woofers, manufactured in France by Focal. With a total RMS power of 200W, it covers a frequency band from 32Hz to 120Hz. Sub One offers great dynamics whilst maintaining low distortion. 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 producers and sound engineers with higher demands in the sub-bass, Focal offers Sub One, a subwoofer that delivers power of 200W 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.
