Using Alpine’s high-strength and lightweight Carbon Fiber Reinforced Polymer (CFRP) technology, R-Series speaker cones can be custom formed so that the fibers align in the same direction as the curve and shape of the cone. This reduces resonate peaks and increases the speakers’ mid-bass performance and dynamic range. CFRP is also used as a tweeter diaphragm, enabling the speakers to perform into 40kHZ range and making them compliant with High-Resolution Audio playback.
An updated hardware design allows R-Series speakers to fit into tighter install locations without sacrificing performance. The updates include a neodymium magnet that gives the speakers a smaller mounting footprint, compared to other speaker brands, and a shallower grill design that will fit into most applications. The speakers use a crossover with an in-line, passive design, and reduced footprint, for easier installation. The tweeters can also pivot approximately 15-degrees in any direction, so they can be angled in an optimal position.
