The “W” composite sandwich cone permits total optimization of the frequency response curve, thanks to the total control of three key parameters: lightness, rigidity and damping. At Focal, the letter “W” means Glass/ Glass, as it usually has two sheets of woven glass tissue that are “sandwiched” onto the structural foam core. The glass tissue benefits from the incredibly fine weaving of very long fibres. This choice offers a mass and a size clearly inferior to those in Aramid fibers or other Kevlar^® fabrics, which generate coloration in the midrange. It’s also important to note that the molecular bond between the resin and the glass is greater than that obtained with Aramid fibres. The cone structure is more homogeneous and its behavior in flex is much more superior.

These unique characteristics of lightness and rigidity provide control of the signal transmission speed inside the material. Adjusting the thickness of the structural foam allows a very precise control of the “W” cone’s damping. The variation of the number of glass fibre sheets and the thickness of the central foam can easily optimize the cone’s behavior according to the desired frequency range.When listening, the sound of the “W” cone is entirely transparent, has an excellent phase response and has a very low distortion rate rigidity 20 times higher than Kevlar^® or Aramid fibre .

Bespoke Adjustments the Ultimate Home Cinema Experience

The direction of the midrange-treble plate can be adjusted and comes in the d’Appolito configuration, allowing it to be perfectly adjusted to the listening position. It can also be positioned in the central, left or right channel, which combined with the option to adjust the level of each speaker driver, allows you to customize your system as desired.
