Alpine R-S65C.2 6.5" Component 2-Way Speaker Set

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. The crossover on the component models uses an in-line, passive design with a reduced footprint, which also contributes to easier installation.
