The Alpine SPR-57C is a set of 5” x 7”, 2-way coaxial car speakers built as an upgrade from the SPS-507. It includes an improved design with a rigid custom-cast aluminum frame, an optimized air-flow design for superior cooling, and a shallow-mounting design for easy installation. Each speaker in this set hosts both a Kevlar Reinforced woofer and a 63/64” swivel tweeter—it can be swiveled up to 10 degrees. Unique about this model is its flat copper wounding, which helps to contribute to the unit’s high-powered 300W power handling. Note also the Alpine SPR-57C’s wide frequency range from 65Hz-22kHz.
