Biaxial horn speaker (PZA)

Twin Reflex Air Column Biaxial Horn Speaker

The BIA-100 is the original reflex horn featuring a biaxial design with twin air columns and an exponential bell for wide-angle coverage with a linear frequency response. The horn provides excellent acoustic loading maintained at 350 Hz low-frequency roll-off and optimizes the delivery of high and midrange signal levels. The BIA-100 is designed for use with AtlasIED PD Series compression drivers and models with 13/8"-18 male threads and 0.707" diameter throat openings.

The easy-to-mount horn features a patented, labor-saving gimbal mounting bracket assembly (U.S. Patent No. 4,325,529), which allows directional positioning up to 180° vertically and horizontally. It includes a steel bracket, a cast mounting base, and provisions for flange installation. The weather-resistant, anti-glare, matte black foam horn is resonance-resistant. The bracket assembly has a durable epoxy finish.
