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. These unique characteristics of lightness and rigidity provide control of the signal transmission speed inside the material.
Due to its incredible rigidity, Beryllium represents the ultimate material for a tweeter dome. After two years of research and development, Focal produced a world first: a pure Beryllium inverted dome, able to cover more than five octaves. You will improve the perception of transients and other micro details.
The pure Beryllium inverted dome tweeter offers a perfectly linear frequency response and extremely precise and detailed treble.
As well, the linearity of the speaker’s response curve is mainly a function of three opposite parameters: lightness, rigidity and damping.
