The shape and materials of the cones are essential. For extremely fine treble, our engineers have patented the inverted dome tweeter, a Focal signature. Forming an inverted dome offers the advantage of low directivity and a small-diameter voice coil, making it very lightweight for better acceleration. The materials themselves contribute to bringing together the key points of a good speaker: aluminum increases the rigidity of the dome and reduces distortion, and the addition of magnesium provides excellent damping. The suspension that connects the dome to its support uses a shape-memory material, Poron. This suspension is derived from the famous Utopia tweeter made of Beryllium and reduces distortion by three between 2000 Hz and 3000 Hz, the area of ​​​​very high ear sensitivity.

Exclusive to Focal, made in France, the Slatefiber cone is made of recycled carbon fibers and thermoplastic polymer. In pursuit of perfection and specialists in speaker cones, our engineers have chosen to use non-woven carbon fibers oriented in the same direction to achieve even greater rigidity, damping, and lightness, the "essentials" of a good speaker. Recognized for its reproduction of dynamic, rich, and balanced sound, this cone has proven itself on numerous products for the home, for professionals in recording studios, and also for listening in cars.
