By developing and manufacturing its cones, Focal pushes the boundaries of acoustic innovation. The "W" cone, known as the "sandwich" cone of the speakers, plays a key role in sound reproduction. It consists of two sheets of glass placed on either side of a central foam body; a sandwich construction that allows for great control of the three key parameters for a good speaker: lightness, rigidity and damping. This cone, the flagship of Focal's expertise, perfectly optimizes the frequency response curve, provides low distortion and total listening transparency. The sound is of ultimate precision.

While the material of a cone is essential, its shape is just as important. Focal engineers developed an "M" profile for the "W" fiberglass cone. This "M" profile is the result of many years of research and our expertise in cone geometries. Made from a single piece (without a core cover), it allows for, among other things, a significant reduction in harmonic distortion, better sound dispersion, and optimal power handling. A major Focal innovation that can be found on many products.

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.
