Focal introduces its long-awaited subwoofer.

Sub One is a testament to Focal's spirit of innovation. Thanks to its precision and extremely low distortion, Sub One provides an ideal complement to the Alpha Evo and Shape lines. For the speaker drivers, the engineers have chosen double-skinned Slatefiber cones. The two aligned cones offer even greater rigidity, ideal for a subwoofer. Thanks to its front-firing ports, Sub One can be easily positioned in any setup, integrating easily into a room, along a wall or under a desk.

The Sub One is composed of two 8" Slatefiber cone woofers, manufactured in France by Focal. With a total RMS power of 200W, it covers a frequency range from 32Hz to 120Hz and provides excellent dynamics.
