A RARE AND PRECIOUS MATERIAL
Beryllium is so rigid that it is the only metal that can scratch glass. It's the material of choice for tweeter diaphragms! Its price - it's 50 times more expensive than gold - makes it a material to be reserved for the best expected acoustic renderings. Today, Beryllium tweeters are used in exceptional Focal products.
EXTENDED FREQUENCY RESPONSE TO 40 KHZ
After two years of research and development, Focal has achieved a world first with the shaping of an inverted dome in pure Beryllium capable of covering more than five octaves (1,000 Hz - 40,000 Hz). What's the point of seeking an extended response to 40 kHz when the human ear hears down to 20,000 Hz? The more extended the frequency response at the top of the spectrum, the better the impulse response, and therefore the better the perception of transients and other micro-details. What's more, the linearity of a loudspeaker's response curve is primarily a function of the balance between three contradictory parameters: lightness, rigidity and damping.
INCREDIBLE ACOUSTIC CHARACTERISTICS
To date, only one material has made it possible to take a decisive step forward: beryllium. For domes of identical mass, Beryllium is 7 times stiffer than titanium or aluminum, materials which offer the same rigidity for equivalent mass. Sound also travels 3 times faster than in titanium and 2.5 times faster than in aluminum. All in all, the frequency response curve, acoustic transparency and impulse response of the Béryllium inverted dome tweeter are perfect, guaranteeing total control of the work to be done.

Tweeter Frak
Perfect treble
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.
EQI system
Easy to install
Sound quality is not enough. That's why Focal adds a valuable criterion for integration products: ease of installation. Thanks to the EQI (Easy Quick Install) system, assembly is greatly improved and facilitated, with installation time reduced to a minimum. This ingenious mechanism allows products to be installed by hand, simply and without tools.
TMD suspension
Stabilized surround, eliminates vibrations
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.
