The Alpine SPR-13C is a set of 5-1/4”, 2-way coaxial speakers engineered as a direct upgrade from the SPS-500. It includes an upgraded design with enhanced detail and sound reproduction, Alpine’s exclusive Linear Drive Motor for greater bass, and resonance absorbers for a smooth, wider-range frequency response. Included in the unit is a Kevlar Reinforced woofer with a 63/64” swivel ring tweeter. The tweeter uses an ultra low distortion magnet design with copper and a large Neodymium magnet, all working together to ensure low distortion with high tonal accuracy. At peak performance, the Alpine SPR-13C handles up to 270W of power along a wide 70Hz-22kHz frequency range.
