Focal Sub One Active Studio Subwoofer

Slatefibre neutrality

Inheriting the evolved design traits of Focal’s Alpha EVO series, Sub One features two 8-inch Slatefiber cone woofers developed in-house by Focal France to offer neutrality as well as detail. Each driver serves a wide frequency response from 120 all the way down to 32Hz.

Power in numbers

Sub One delivers 200W of total RMS power along with a high level of control. Low-pass crossover, polarity, phase and of course volume can all be fully adjusted to user requirements.

For dealing the subwoofer in and out quickly, an external footswitch output is also available to cut the Sub One in and out with the tap of a button.

Easy integration

The rear panel of the Sub One is armed with balanced 3-pin XLR inputs and outputs, along with a dedicated LFE “Low Frequency Effect” input and output management system for optimum satellite configuration.

Thanks to its neutral shape and build, Sub One easily integrates into almost any workspace and can be placed directly against a wall or under a desk without impacting on performance.
