AtlasIED DR-54 DR Series Uniform Coverage Horn | 75°

The AtlasIED DR-54 is a double re-entrant paging horn engineered for integrators and facilities managers who need reliable, wide-coverage voice communication in demanding environments. Its primary applications include outdoor public address, industrial plant PA, warehouse paging, and campus-wide voice notification systems where ambient noise levels make standard loudspeakers impractical.

The DR-54 accepts any compression driver with a standard 1 3/8"-18 male thread coupling, including AtlasIED PD and SD Series drivers, giving installers flexibility to match existing system components without adapters or custom hardware. The circular projector design incorporates a resonance damping ring that extends usable frequency response, supporting both high-intelligibility speech and background music applications — a meaningful advantage over single-projector horn designs that roll off early. The integral U-type steel mounting bracket allows multi-axis directional aiming, a critical feature for outdoor installations where coverage geometry must account for irregular site layouts.

Weather-resistant, all-metal exponentially-flared construction finished in durable grey epoxy makes the DR-54 suitable for year-round outdoor deployment without enclosure upgrades. The 75° dispersion pattern provides uniform coverage geometry appropriate for single-zone coverage of large horizontal areas, reducing the number of fixtures required compared to narrower horn designs.
