The SDA 1 delivers remarkable depth and imaging, powered by dual midrange drivers, a dimensional array driver, and a smooth, detailed tweeter per cabinet. Built during the golden era of American hi-fi, these speakers combine craftsmanship, clarity, and musical warmth, making them sought after by collectors and audiophiles alike.
