As the key component of a loudspeaker, the membrane is at the heart of our acoustic engineers' research. After more than five years of research and development, in 2013 Focal unveiled an exclusive membrane made from flax. Patented, this Flax cone is a sandwich made of very high quality French flax fibre placed between two thin sheets of glass fibre. It satisfies all the criteria of a high-fidelity membrane: lightness to offer good dynamics, rigidity to hold the bass and damping to deliver a neutral, natural, uncolored sound. It is an emblematic Focal innovation in many hi-fi products.

Membrane shape and materials are essential for high-fidelity reproduction. Focal engineers have designed the TAM tweeter. Manufactured in our workshops in France, it boasts a number of advantages, particularly in terms of wide-angle diffusion. Comprising an aluminum/magnesium inverted dome cone with an "M" profile for even greater rigidity, it delivers flawless harmonic balance and detailed treble. The presence of a decompression chamber limits disturbances caused by rear waves, for even greater sonic clarity.

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.
