Alpine X-S65 X-Series 6.5 Inch Coaxial 2-Way Speakers SPECIFICATIONS Woofer: 6-1/2" cone Tweeter: 1" Carbon Graphite Maximum Peak Power: 330 Watts Maximum RMS Power: 110 Watts lmpedance: 4 ohms Sensitivity: 89 dB SPL (1W @ 1m) Frequency Response: 55 Hz to 50 kHz Mounting Depth/Drop-in Mounting: 2-5/16- (5.9cm) Cutout Diameter: 5-13/32- (13.7cm) circle Recommended Amplification: up to 110 watts RMS per channel Warning: This product contains a high performance tweeter. If there is a tweeter already installed in your car, then you must disconnect its terminals. If you leave the original tweeter connected and connect this product in parallel, then a fault may develop in this product, so you are strongly recommended not to do so. 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.
