The R-Series speakers use Alpine’s exclusive cone technology, Carbon Fiber Reinforced Polymer (CFRP), which is a high-strength, lightweight material. CFRP can be custom-formed so that its fibers align in the same direction as the curve and shape of the cone, thereby reducing resonant peaks and increasing the speakers’ mid-bass performance and dynamic range. CFRP is also used as a tweeter diaphragm, enabling the speakers to perform into the 45kHz range and making them compliant with High-Resolution Audio playback.
Talc, a common mineral used in products such as baby powder and paint, has been found to have incredible damping properties while being less dense than the traditional Mica filler used in dust caps. By adding a calculated amount of talc to the mica polypropylene in the dust cap, Alpine were able to increase vibration absorption of the cap while lowering the density. The resulting lighter dust cap contributes to a faster attack and a more accurate reproduction of low frequencies.
