For perfectly reproduced high frequencies, Focal engineers research and develop specific tweeter cones. Shapes and materials play a key role in reproduction. For the FRAK tweeter cone, they chose aluminum/magnesium, which they combined with an "M"-shaped profile. This revolutionary combination in car audio offers a beautiful frequency drop and superb damping. The lightness of the cone allows the tweeters to shine in the extreme treble.

At the rear of the membrane is the spider, which holds the lower part of the cone. By working on this essential element of the speaker and in particular by developing a spider with a progressive profile, our engineers have achieved better damping of the movements of the sandwich membrane, greatly improving the linearity, precision and dynamics of the sound.

While our engineers are experts in developing exclusive cones, they also innovate for all the elements that make up the speakers, such as the suspension that connects the cone to the chassis and whose performance is essential to control. Created in 2015, TMD (Tuned Mass Damper) technology with harmonic damping consists of the addition of finely positioned toroidal weights, allowing the suspension to be stabilized for ever greater sound neutrality. This technology enhances the midrange and the erratic behavior of the suspension between 1kHz and 2KHz.
