The cone, the centerpiece 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 fiber sandwich cone, recognizable by its unique yellow color. It has been extensively updated over the years while retaining the characteristics that made it so successful. Today, it consists of an ultra-light foam core sandwiched between a layer of aramid fibers and a layer of glass fibers. It combines the three key factors of a loudspeaker cone: rigidity, lightness, and damping, for precise, dynamic, and uncolored sound.

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.
