The Atlas Sound BIA-100 High-Efficiency Bi-Axial Horn Provides 130° x 60° Wide-Angle Sound Coverage is the original reflex horn featuring a bi-axial design with twin air columns and exponential bell for wide-angle coverage with a linear frequency response. Ideal for High-Intelligibility Voice, Signaling and Full-Range Music in Indoor/Outdoor Applications.

The horn provides excellent acoustic loading maintained to a 350 Hz low-frequency roll-off and optimizes delivery of high and mid-range signal levels. BIA-100 is designed for use with AtlasIED PD Series compression drivers and models having 13/8" -18 male threads and 0.707" diameter throat openings.
