8″ (20cm) Flax Cone Subwoofer

P20F is a 20cm (8″) subwoofer equipped with 320 gr/m² Flax cone for deep and controlled bass. It can work in both 10-liter-closed and 13-liter-bass-reflex cabinets. It provides 250-Watts RMS and a frequency response from 39 to 500Hz. This subwoofer is ideal for a small bass enclosure perfectly integrated in the vehicle.

The three Flax subwoofers consist of straightforward 4-Ohm voice coils which are perfectly suited for small enclosures (closed or bass-reflex). Several innovations raise their performance to an even higher level. Each model of subwoofer has a dual magnet, offering improved linearity and ensuring optimal magnetic power delivered to the voice coil, which features a new cooling system. Glass fibre has been used for the mounting of the voice coil, making it more robust while protecting the cone from the heat emitted. Last but not least, the new fixings connecting the cone to the voice coil and the spider to the basket improve reliability for extreme use (very high excursion).

Description

Advantages:

“Dual Magnet” for more power
FLAX® technology for an exclusive cone
High rigidity for deep and controlled bass
Improved excursion thanks to the new suspension
Optimized cooling of the voice coil
The best compromise for a small seal enclosure volume using (0.35 Cu ft – 10L)

NATURAL SOUND:

Its lightness makes it very dynamic, while the stiffness offers great bass and it is well damped to deliver neutral, natural sound. Flax is twice as light as fiberglass, because it is a hollow fibre. The very low elasticity makes it ideal for increasing the modulus of flexural rigidity within a sandwich structure.

ADVANTAGES:

Shallow and lightweight
“Dual Magnet” for more power
FLAX® technology for an exclusive cone
High rigidity for deep and controlled bass
Compact size for sealed enclosure
High excursion
Fiberglass voice-coil material for overheating reduction
Rubber surround catenary profile for Long life, reliability, and high excursion

Development

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.

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.

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

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.
