2-WAY IN-WALL LOUDSPEAKER – 1000 IW6
IN-WALL HI-FI SOUND
The 1000 IW6 closed-back loudspeaker offers a truly compact and invisible alternative to a traditional indoor acoustic installation. Thanks to its high-quality sound performance, it is the obvious choice for a Home Cinema system, particularly as a rear channel in-wall integration. Offering cutting-edge acoustic technologies exclusive to Focal, such as the Beryllium tweeter and ‘W’ cone, this made in France loudspeaker offers sound reproduction that combines musicality and power. Thanks to its adjustable feature at the tweeter level, you can ensure your installation is optimised to your listening room.
This 1000 Series range of loudspeakers embodies Focal excellence for the most sensational—and discreet—listening experience.
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).
RARE AND PRECIOUS BERYLLIUM
Due to its incredible rigidity, Beryllium represents the ultimate material for a tweeter dome
Focal, after two years of research and development, produced a world first: a pure Beryllium inverted dome, able to cover more than five octaves (1000Hz – 40kHz). You may ask yourself why do we strive for an extended response at 40kHz, if the human ear can only hear up to 20kHz? If you can extend frequency response, you will improve the perception of transients and other micro details. As well, the linearity of the speaker’s response curve is mainly a function of three opposite parameters: lightness, rigidity and damping.
To this day, only one material permits a joining of these parameters: Beryllium. For domes with identical masses, Beryllium is seven times more rigid than Titanium or Aluminum, the latter two well known for their rigidity. This results in a sound wave propagation three times faster than Titanium and two and a half times faster than Aluminum. In the end, the linearity of the frequency response curve, the acoustic transparency and the impulse response of the Beryllium tweeter are maximized and offer near-perfect sound.
THE ULTIMATE HOME CINEMA EXPERIENCE
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, enhancing 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.
