The Liberty DR-72 Atlas Sound DR Series double re-entrant horns are designed for use with compression driver units to offer superior music and voice communications over distance and ambient noise. The circular projectors are equipped with a resonance damping ring for best response through an extended frequency range. Weather-resistant units will accommodate Atlas Sound PD and SD Series compression drivers or any driver with standard 1 3/8" -18 male thread coupling. The integral "U-type" steel mounting bracket provides maximum directional aiming flexibility and enhances installation capability when used outdoors or in industrial environments. The rugged all-metal, exponentially-flared horns are finished in durable grey epoxy.

The DR Series double re-entrant horns have proven their capability and ruggedness in permanent and temporary applications in recreational, commercial and industrial applications for over sixty years. When used with PD or SD Series compression drivers, they assure intelligible audio transmission over long distances or through high background noise levels and are consistently recommended for sport facilities, amusement parks, church towers, warehouses, factories, military sites, transportation terminals, and other environmentally demanding locations.
