Alpha Twin Evo

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.

Exclusive to Focal and made in France, the Slatefiber membrane is made from recycled carbon fiber and thermoplastic polymer. In their quest for perfection and as specialists in loudspeaker membranes, our engineers have chosen to use non-woven carbon fibers in this case.es in the same direction to achieve even greater rigidity, damping and lightness, the "essentials" of a good loudspeaker. Renowned for its dynamic, rich and balanced sound reproduction, this membrane has proved its worth on numerous products for the home, for professionals in recording studios, and also for listening in the car.
