Alpine S2-S50

Newly designed and Hi-Res Audio certified, this next generation S-Series S2-S50 13 cm (5 inch) coaxial speaker offers a new standard for entry-level audio performance.

These speakers are packed with superior performance, utilizing high-performance materials and Alpine's unique design elements. The lightweight bass cone, made from a combination of polypropylene, fiberglass and mica materials, delivers the essential
