ACTIVE SUBWOOFER

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.
