Despite its small size, the Aria 905 bookshelf loudspeaker is capable of reproducing sound worthy of a much bigger loudspeaker whilst providing very natural sound without any artificiality. Composed of a 5" (13cm) woofer with Flax sandwich cones, it provides a very high-definition and natural sound. Bass is articulated and controlled thanks to the oversized magnetic motor of the midrange/bass speaker driver and to low distortion aerodynamic front vent.
For the treble register, the speaker is equipped with one TNF aluminium/magnesium inverted dome tweeter with Poron suspension for smoother sound. Their Urethane waveguide improves thus horizontal directivity and provides a more precise sound image.
Focal brand's signature product, the inverted dome tweeter has been continually developed ever since it was created. It bears repeating that its main advantage, apart from its very low directivity, lies in its use of a coil of small diameter (hence very light and better accelerating) directly fixed to the rigid dome.
Just as with the cones of its bass and midrange speaker drivers, what makes Focal unique is working directly on the sound output and, therefore, on the mechanical characteristics of materials. When Focal introduced the pure Beryllium inverted dome tweeter ten or so years ago, it demonstrated the decisive advantage of this exclusive technology.
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! The result of more than five years of research and development, F cones 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.
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.
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.
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.
