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.
