AESTHETICS AND PERFORMANCE

After more than four years of Research & Development, in 2019 Focal unveiled a new technology with remarkable performance: the Slatefiber cone. 

Manufactured in France, this cone is characterised by its dynamic, rich and ultra-balanced sound, particularly in the midranges. With its acoustic qualities and unique “slate effect”, it has become a benchmark for High-Fidelity in its price category.

AN AUTHENTIC COMPOSITE 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.
