MORE OUTPUT FOR MORE FUN The woofers have a large, 35-millimeter (mm) voice coil which allows for more coil windings to fit in the gap. The R-Series speakers incorporate Alpine's patented High-Amplitude Multi-Roll Surround H. The component models use a crossover with an in-line, passive design and reduced footprint, which contributes to easier installation. EXCLUSIVE CONE TECHNOLOGY 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. BETTER FITMENT WITHOUT SACRIFICING MOTOR FORCE The R-Series speakers use a neodymium magnet which gives them a shorter overall height, compared to other speaker brands.The R-Series speakers also use a new, shallower grill design. The result: An improved fitment design that lets the R-Series speakers fit into tighter install locations without sacrificing motor force. CTA-2031: 100W RMS per speaker/300W Peak Power per speaker.
