AtlasIED BIA-100 Bi-Axial Horn Speaker with Twin Reflex Air Column

Designed for clear, reliable mass notification and security audio, the AtlasIED BIA-100 Bi-Axial Horn Speaker is a purpose-built horn flare for public address, emergency voice evacuation and surveillance-driven alerting. This high-efficiency bi-axial horn delivers wide-angle 130° x 60° coverage and a focused nominal frequency response from 350–8,000 Hz to maximize speech intelligibility and alarm clarity in both indoor and outdoor environments. The BIA-100 accepts standard 1 3/8-inch -18 thread compression drivers with a 0.7-inch throat, making integration with Atlas Sound PD Series drivers straightforward for contractors and systems integrators. Installers benefit from the patented 180° gimbal-mount that lets you precisely aim sound toward critical zones, reducing the total speaker count and simplifying layout for campuses, transportation hubs, and secure facilities. TAA/NDAA compliance and a durable design ensure the BIA-100 meets government and enterprise procurement requirements.
