The cone, critical component of the speaker, cone technology:

The speaker is at the heart and in the tradition of Focal production. For over 30 years we have explored the various possibilities offered by innovative materials to create the ideal speaker cone. The list is long: Polyglass, K2 sandwich, W sandwich, Kevlar, Titanium, Beryllium, Aluminum/Magnesium. The meaning of this constant research comes from the awareness that the cone is the critical interface for the speaker. Critical because it is the part of the speaker that sets air molecules in motion and the fidelity of acoustic transfer depends on the quality of the materials used.
Currently for our Home, Car and Pro productions, we use two different types of cones for midwoofers: Polyglass for less expensive products and sandwich cones for top series (Utopia and K2 Power).
Sandwich cones are entirely hand-made and therefore have limited use due to high costs.

"Sandwich" technology for rigidity
The ideal cone must satisfy 3 contradictory characteristics:
1. lightness to allow fast accelerations
2. rigidity so it functions as a piston
3. high damping to not interfere with sound

Today it is practically impossible to use a single material to make cones capable of satisfying the three points above, while solutions that use a mix of materials offer broad possibilities.
In particular, sandwich construction, in which two very thin fiberglass films contain a core made of a different material, is an unbeatable technology for cone rigidity.

The core of a "sandwich" cone provides mechanical damping that is responsible for the acoustic neutrality of the cone.

What material to use for the core?
Focal patented in 1995 the cone called "W SANDWICH" consisting of a core made of acrylic and plexiglass foam. Unfortunately, the type of core of the "W sandwich" cone affects its processing, which must be done by hand. This severely limits its use for obvious cost reasons.
Over the past three years our engineers have analyzed and tested several materials in search of one suitable for the core of a sandwich cone that can be manufactured by industrial processes rather than by hand. And they looked especially among natural materials, less subject to price fluctuations typical of petroleum-derived materials.

FLAX (Linen)
FLAX, given its characteristics, very quickly became a valid candidate and at the end of tests, analyses and comparisons proved to be the ideal material for the core of a "popular" cost sandwich cone. Basically we found the solution around our home, as France is the world's largest producer of linen considered among others of the best quality. But there are other reasons that made us prefer it.

The unique qualities of FLAX
Composite materials have properties suitable in applications where rigidity and low specific weight are required. They have, however, a serious drawback which is the lack of damping that leads to poor vibration control.
For this reason it is often necessary to add damping material for the absorption of intrinsic vibrations of the material. FLAX is twice as light as fiberglass, as the fiber has cavities. It also has very low elasticity which is ideal for increasing sandwich rigidity. Furthermore, it can be obtained in "non-woven" bundles of considerable diameters and thus produce the thickness required by the sandwich.

Flax combines the 3 key factors required by the core of speaker sandwich material:
