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 can now reveal a new cone made of high-quality flax fibers. F cone are characterised 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 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 pricecompetitive.

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 pricecompetitive product ranges

Parece interessante!

Poxa o povo é criativo mesmo...

Comentei sobre essa tecnologia em outro tópico. Na verdade, quase comprei um kit desse. Acredito que tenha bons médios.

Essa linha da Focal veio para substituir parte da Polyglass, como o V30. Acredito tenham corrigido o tw. Além disso, agora o crossover permite bi-amp.

cá entre nós.. era até estranho uma empresa como a focal não ter em seu cross a possibilidade de bi-amp..

to curioso sobre essa tecnologia.. com o tempo veremos se é boa ou não..

Não entendi exatamente qual seria a vantagem para o Kevlar?? Preço?? Damping Factor??

Material leve, resistente, barato, timbre melhor (talvez), etc.

eu só truco no barato..
