The Infinity Alpha 693M is a robust 6×9″ 3-way coaxial speaker system built to deliver exceptional clarity, volume, and dynamic range for car audio enthusiasts looking to elevate their sound experience. Engineered with Infinity’s patented Plus One™ woofer cone architecture, the Alpha 693M produces deeper, more resonant bass, while its dedicated midrange driver and PEI balanced dome tweeter ensure rich vocal clarity and detailed highs. The three-way configuration makes this speaker ideal for rear deck or door placements where full-spectrum sound and staging matter most.
