TECHNOLOGIES

ALUMINUM TWEETER

Treble finesse

Manufactured by Focal, the inverted dome tweeter has been a signature since 1981. It offers the property of being a true micro-loudspeaker. The curvature of the dome is much less pronounced than that of positive domes. This results in better space dispersion and very low directionality, unlike ribbon tweeters. The inverted dome tweeter therefore generates unrivalled dynamics. In addition to dome shapes, our engineers also work on materials. In this case, they chose aluminum, which increases dome rigidity and reduces distortion. And to perfect the spatialization of sound, a waveguide has been developed. Horizontal frequency response is within +/- 0.5 dB. This performance guarantees an incredibly stable soundstage.


POLYGLASS MEMBRANE

Well-defined mids

The diaphragm, the key component of a loudspeaker, is at the heart of our acoustic engineers' research. Polyglass technology, exclusive to Focal, consists of applying fine glass microbeads to a cellulose pulp cone. This process reconciles the excellent damping of paper with the rigidity of glass. The stiffness index is almost 10 times that of polypropylene. Adjusting the mass-rigidity-damping ratio results in a remarkably linear frequency response curve, right from the membrane design stage. This innovation also significantly increases definition in the midrange register.
