FOCAL 1000 IW SUB UTOPIA LCR

With the ability to be positioned horizontally or vertically, 1000 IWSUB Utopia has been designed to assemble perfectly with the 1000 IWLCR Utopia 3-way in-wall loudspeaker. It enhances the performance of your Home Cinema installation. The option to customise the impedance of the speaker drivers according to the number of products assembled allows the system's performance to be adjusted to enjoy an exceptional, bespoke installation.

THE “W” COMPOSITE SANDWICH CONE

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 behaviour 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 disortion rate (rigidity 20 times higher than Kevlar^® or Aramid fibre).
