"X" technology
Not only does it support all sources and draw out all the music information contained therein, but it also reproduces the realistic sound field space, the emotion of the music, and even the artist's thoughts.
Setting unprecedentedly high goals, accumulating overwhelming technical strength and thorough development and verification, after 14 years, we have now reached an "unexplored sound" that car speakers have never experienced before. We arrived.
Real Dynamic – ALPINE “X”. True innovation starts here.
Carbon graphite diaphragm delivers unprecedented resolution
The ALPINE "X", which seeks overwhelming resolution even in the ultra-high range, uses carbon graphite, a material that combines amorphous carbon and graphite, for the tweeter diaphragm.
Used in high-end home audio speakers, this material offers extremely high resolution compared to other materials commonly used in car audio speakers.
This makes it possible to realistically reproduce even the subtle nuances and atmosphere of the sound source itself.
