APPLICATIONS
Bi-axial horn Model BIA-100 delivers outstanding sound dispersion
and audio efficiency when used with medium or high powered
compression drivers. 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, recrea-
tion/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 1

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
