The Alpine SPR-17C is a set of 6-1/2”, 2-way coaxial car speakers engineered to outperform its predecessor, the SPS-600. A leap up from the past, the SPR-17C utilizes an upgraded design with better balancing & staging, an enhanced edge-wound voice coil for greater linear movement, and an ultra-low distortion magnet design for low distortion with a high tonal accuracy. With all the components combined, the Alpine SPR-17C delivers over 300W along an ultra-wide 65Hz-22kHz frequency range. Note also that the 63/64” included tweeter is swivel-enabled, allowing users to twist and turn it to their preferred angle.
