Alpine’s top sound engineers from all over the world gathered in the Alpine Iwaki, Japan headquarters to critically evaluate in-car sound from aftermarket and high-end factory systems. While many of these systems were able to perform with wide dynamic range and at sufficient volume levels, there was a lack of reality of instruments, but most predominantly in most systems, a lack of spatial imaging. As a result, Alpine ID was born to address this need.
Alpine ID, which stands for “Alpine: Image Defined,” is Alpine’s new global philosophy with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of stage. The Alpine ID philosophy centers on developing matched sound systems that work together to create a highly realistic sound stage with great dynamic range (Hi-Res Audio) and sound quality. The matched sound system components allow the listener to experience a new level of realism and engagement while enjoying music in their vehicle. In other words, the listener can experience the music as the artist originally intended. The X-Series speakers, amplifiers, and subwoofers create the foundation of sound system components that will feature Alpine’s new sound philosophy.
Alpine uses high-power neodymium magnets for the new X-Series speakers. This means the magnet can be much smaller compared to traditional speaker designs, allowing for a much lower mounting depth and overall space requirement inside the car door.
All New Motor Structure
By using a powerful Neodymium magnet in a radial configuration, we could achieve a very compact motor assembly for a high vehicle compatibility rate. The radial magnet configuration drastically increases magnetic efficiency – resulting in high dynamic and power handling.
The High Amplitude Multi-Roll (HAMR) surround allows a maximum, linear cone excursion for high SPL, while maintaining full control over the diaphragm at any excursion stage for highest sound clarity.
Included Mesh Grill
We included a metal mesh grill to protect the woofer in open installations.
X-Series Motor Linearity
We needed to create a speaker with balanced motor force throughout its operating range of motion. A balanced force factor curve should look identical / mirrored when the cone moves in or out. The Alpine X-Series speakers offer excellent linearity for highest clarity.
The small-diameter nano-fibers create a cone structure that is lightweight and rigid, for increased sound accuracy. Nano-fiber cones also have good internal damping, so residual energy decays quickly without distorting the original music tones.
X-Series Speakers Frequency Response
We aimed to create a speaker system with extended high frequency response to faithfully reproduce the sound stage and the harmonic details of the music.
New Carbon Graphite Tweeter
Alpine chose carbon graphite for the tweeter because it is rigid enough to perform like a hard dome tweeter but maintains the natural sound characteristics of a soft dome tweeter. The tweeter delivers increased accuracy and extended high frequency range (up to 40kHz) without the harshness that is sometimes associated with hard dome tweeters. This allows listeners to enjoy true Hi-Res Audio sound quality.
