FLAX FIBER, UNIQUE SKILLS
Dôme Flax is a high-end system made in France, characterized by its miniature and « high-tech » design. Thanks to its Flax cone, made of linen, this 5.1 system gets a major improvement in definition and intelligibility of dialogues as well as a larger spacialization thanks to a better linearity of the frequency response. A true return to nature for your films!
Room size: 320ft2 to 430ft2
The Dôme Flax system is associated with the wireless subwoofer Sub Air for a 5.1 configuration. Free from any cables, Sub Air offers an intense and deep sound and perfectly fits into all kinds of spaces with its flat and compact design.
FLAX SANDWICH CONE
Made in France but affordable, Flax cones are oriented towards acoustic performance, high-tech and give an original design to the brand’s speaker drivers!
After more than five years of research and development, engineers at Focal reveal in 2013 a new cone made of high-quality flax fibers. F cone are characterized by their natural sound, with low coloration, their richness of reproduction in the midrange register and their tighter bass.
THE UNIQUE QUALITIES OF FLAX
F cones are made of high-quality flax fibers core enclosed by two thin layers of glass fiber. They satisfy the key criteria of a high performance diaphragm : high internal damping, high velocity of sound and high flexural rigidity.
Rigidity
All these criteria cannot be met by a mono-material cone. Sandwich technology greatly influences the neutrality of the sound produced by the cone, something, which has always been Focal’s hallmark. The expertise gained from the sandwich technology of the Utopia and K2 Power ranges enabled Focal to develop a revolutionary flax-fiber cone conciliating the 3 criteria.
Lightness
FLAX FIBER, UNIQUE SKILLS
Flax is twice as light as fiberglass, because the fiber is hollow. It also has very low elasticity which makes it ideal to increase the flexural rigidity of a sandwich structure. Moreover, it can be obtained in non-woven bundles of considerable diameter and it can therefore produce the thickness required for a sandwich.
Internal damping
Composite materials have properties suitable for applications where both rigidity and low mass are required. However, their disadvantage is that they lack damping, which leads to very poor control of vibrations. Recent developments in this field combining composites and natural fibers have brought unexpected opportunities. Flax fiber has an excellent internal damping of the same order of magnitude as the glass or Kevlar® fibers or aluminum.
MADE IN FRANCE AND AFFORDABLE
Flax cones are designed and manufactured in France, from French flax fiber. France is the main cultivator in Europe of fiber flax, principally in Flanders, Picardy, Normandy and the Pas-de-Calais region. French flax is considered the best in the world.
Synthetic fibers or foams originating from petrochemical resources are subject to inflation linked to the sharp rise in crude oil prices. Organic or ecological textiles, like flax, are thus becoming more and more price competitive.
Because the “W” or “K2” sandwich have to be manufactured by hand, their range of application remains limited for reasons of cost. The industrial process developed to manufacture the “F” cones bring it within reach of very price competitive product ranges.
