AtlasIED DR-54 DR Series Weatherproof Double Re-Entrant Horn, 75° Uniform Coverage

Built for clear, reliable mass notification and security paging in challenging environments, the AtlasIED DR-54 DR Series weatherproof double re-entrant horn delivers high intelligibility for voice, music and emergency signals. This AtlasIED horn speaker provides 75° uniform coverage and a 26" diameter projector to maintain even sound pressure across plazas, transit hubs, warehouses and industrial sites. The DR-54 accepts standard compression drivers (1 3/8"-18 male thread) so it easily integrates with AtlasIED PD/SD drivers or third-party high-efficiency drivers. Its resonance-damping ring and exponentially flared metal horn improve frequency response and minimize distortion for clearer voice transmission — critical for security, surveillance and live monitoring applications. Built for outdoor use, the rugged all-metal, weatherproof housing with gray epoxy finish is TAA and NDAA compliant and backed by a 60-month limited warranty. Specify the DR-54 for mass notification, public address, transportation paging, or campus safety systems where dependable, directional coverage is required. Contact your dealer or add to your security project spec to ensure reliable, intelligible notification across your site.
