The diaphragm, the key component of a loudspeaker, is at the heart of our acoustic engineers' research. Shape and materials are essential for high-fidelity reproduction. In 1986, our teams unveiled an aramid fibre sandwich membrane, recognizable by its unique yellow color. It has been extensively renewed over the years, while retaining the characteristics that made it such a success. Today, it consists of an ultra-light foam core sandwiched between a layer of aramid fibre and a layer of glass fibre. It combines the three key factors of a loudspeaker membrane: rigidity, lightness and damping, for a precise, dynamic and uncolored sound.

The compression tweeter has been designed for limited installation space, without degrading the sharpness and clarity of Focal's signature sound. This type of loudspeaker is combined with our patented "M-profile" technology. This brings two decisive advantages: even lower sound directionality, for an ever more flexible listening position, and a significant gain in stiffness for the dome, which further reduces distortion and thus delivers quality sound.
