Specifications: CTA-2031 Specifications: 100W RMS, 300W Peak, 4 Ohm Frequency Response: 60Hz-40kHz Sensitivity 90 dB SPL (1W @ 1m) Mounting Depth - 2-29/32" (7.4cm) Cutout Diameter - 5-7/8"x8-5/8" oval 100 Watts RMS 300 Watts Peak Ultra Smooth 1" CFRP Tweeter Swivel Tweeter Mounting H.A.M.R. Surround (Patent Pending) CFRP Woofer Cone Large 35mm Square Wire Dual-Layer Voice Coil High-performance Linear Drive Motor The R-Series speakers have been designed from the ground up utilizing an Alpine exclusive cone technology, CFRP: Carbon Fiber Reinforced Polymer. This high-strength, yet lightweight material is formed so that its fibers align in the same direction as the curve and shape of the cone, thereby reducing resonant peaks. As the ultimate balance of light weight and rigidity, CFRP increases the speakers’ mid-bass performance and dynamic range. In addition, CFRP is used as a tweeter diaphragm, enabling the system to perform up into the 45kHz range, making the speakers compliant with High-Resolution Audio playback. The woofers have a larger 35 millimeter (mm) voice coil for increased motor control over the bass output. The R-Series speakers incorporate Alpine’s patented High-Amplitude Multi-Roll (HAMR) surround, for control and accuracy. Overall, the R-Series speaker is smaller, making them ideal for tight installations and use matching speaker grills that are shallower as well.
