Alpine X-69C X-Series 6x9 Inch Component 2-Way Speakers CTA-2031 Specifications: 120W RMS, 360W Peak, 4 Ohm Frequency Response 60Hz-40kHz 1 Inch Carbon Graphite Tweeter Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate in-car sound from aftermarket and high-end factory systems. Many systems had a wide dynamic range and reached sufficient volume levels, but lacked the reality of instruments and spatial imaging. As a result, Alpine ID was developed to address this issue. All-New Design for Overall Improved Performance The all-new designs are built for maximum linear motor force for realistic reproduction of any type of sound source. Premium materials were meticulously selected to contribute the performance of the X-Series speakers: New radial neodymium motor structure: A pole-type neodymium magnet positioned inside the voice coil (as opposed to outside) creates an improved magnetic circuit with less loss for more efficient power delivery. Since the magnet is smaller than conventional designs, it allows the depth of the X-Series speakers to be much shallower and thereby compatible with more vehicles. New nanofiber cone: The small-diameter nanofibers create a cone structure that is lightweight and rigid, for increased sound accuracy. Nanofiber cones also have good internal damping, so residual energy decays quickly without distorting the original music tones. 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 without the harshness that is sometimes associated with hard dome tweeters.
