AtlasIED CD64 Constant Directivity Re-Entrant Paging Horn with 60‑Degree Horizontal and 40‑Degree Vertical Coverage

The AtlasIED CD64 is the industry’s only constant directivity re-entrant horn, delivering greatly improved uniform sound coverage compared to traditional conical horn designs. With a precisely controlled horizontal coverage pattern of 60‑Degree by 40‑Degree vertical dispersion, this horn ensures predictable beamwidth control, making it ideal for high-intelligibility voice and signaling in both indoor and outdoor environments.

Constructed from durable polyester resin and glass-fiber laminate integrally molded to a die-cast zinc throat section, the CD64 is built for rugged use and long-lasting performance. It features the proven CJ46 style heavy-duty steel mounting bracket with a positive locking mechanism for secure horizontal and vertical positioning, whether installed singly or in stacked multi-unit clusters. Compatible with all AtlasIED PD Series compression drivers via standard 1 3/8"-18 female threads, it offers flexible driver options including the PD30, PD-5, and PD60 series.
