200W bi-amped powered studio subwoofer featuring dual 8" woofer with Slatefiber cones

The Focal Sub One powered studio subwoofer delivers 200W RMS of sub-bass, for producers and sound engineers that demand more low-end. 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.

Focal Sub One key features:

• 2 x 8” (20cm) woofers with Slatefiber cone made in France
• 200 W RMS amplifierSound neutrality, precise control of bass equalisation
• Compact design, optimal integration
• Multiple settings: low-pass crossover, volume, Footswitch input, etc.
• LFE, left and right inputs / left and right outputs 
• Reproduction of sonic micro-details; precise adjustment of signal compression

Focal’s patented Slatefiber cone

The Slatefiber cone is a composite cone comprising recycled non-woven carbon fibres - Focal is the first brand in the audio field to use recycled carbon fibres in its speaker drivers - and thermoplastic polymer. The combination of these two materials results in excellent acoustic performance, in terms of sound velocity as well as rigidity and damping.

RIGIDITY
The carbon fibres alone provide an extraordinary rigidity. What’s more, as they all oriented in the same direction, these fibres further increase the speaker driver’s rigidity, and therefore enable more bass to be achieved.

DAMPING
The carbon fibres are therefore aligned, but also non-woven to ensure better damping. Thermoplastic polymer is also located within the fibres to provide the bond between them and increase damping. 

LIGHTNESS
During the development phase, special attention was paid to the weight of the cones to optimize sensitivity: the carbon fibres are very light. In addition to rigidity and damping criteria, the Slatefiber cone therefore meets the speaker driver’s lightness requirement.
