Unit features exponentially-flared projectors which eliminate phase cancellation, control low-frequency roll off and offers maximum results in professionally-applied voice, music and signaling systems. It can be surface or flange-mounted and is ideal for use as a mid-range component for two and three-way, high-fidelity loudspeaker systems. Weather-resistant construction is suitable for permanent or portable installation in church, recreation/sport centers, mass transit terminals, industrial, commercial, educational and institutional facilities. GENERAL DESCRIPTION Model BIA-100 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. 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 Atlas Sound PD Series compression drivers and models having 13/8" -18 male threads and 0.707" dia. throat openings. Refer to PD Series compression driver specification sheets for high-pass filter requirements. Transformer-equipped drivers are available (power-tap information is outlined on individual compression driver specification sheets). The easily-mounted horn features the labor-saving patented gimbal-mount bracket assembly (U.S. Patent # 4,325,529) which allows for directional positioning up to 180" vertically and horizontally. It includes a steel bracket, cast-mounting base and provisions for flange installation. The weather-resistant, non-glare matte black foam horn is resistant to resonance. Bracket assembly is finished in durable epoxy. Overall dimensions are 21"W x 10X"H x 19X"D (533 x 260 x 489 mm). Weight is 16 lbs.
