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. 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.
