Tweeter FRAK

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

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

While our engineers are experts in the development of exclusive diaphragms, they also innovate in all the components that make up the loudspeakers, such as the surround that connects the diaphragm to the frame, the performance of which must be mastered. Introduced in 2015, Tuned Mass Damper (TMD) technology with harmonic damping consists of the addition of finely positioned toroidal weights to stabilize the surround for even greater sonic neutrality. This technology enhances the midrange and the erratic behavior of the surround between 1 kHz and 2 kHz.
