Atlas Sound BIA-100 Bi-Axial Wide-Angle Twin Reflex Air-Column Horn Loudspeaker with Gimbal-Mount

Discover the Atlas Sound BIA-100 Bi-Axial Wide-Angle Twin Reflex Air-Column Horn Loudspeaker with Gimbal-Mount, a pioneering solution in audio technology. This original reflex horn is engineered with a bi-axial design featuring twin air columns and an exponential bell, ensuring wide-angle coverage and a linear frequency response. The BIA-100 excels in acoustic loading, maintaining a low-frequency roll-off at 350Hz, and is optimized for delivering high and midrange signal levels with precision.

Specifically designed for compatibility with Atlas Sound PD Series compression drivers, the BIA-100 accommodates models with 13/8" -18 male threads and 0.707" diameter throat openings. For detailed high-pass filter requirements, refer to the PD Series compression driver specification sheets. Transformer-equipped drivers are also available, with power-tap information provided on individual compression driver specification sheets.

The BIA-100 features a patented gimbal-mount bracket assembly (U.S. Patent #4,325,529), which simplifies installation and allows for precise directional positioning up to 180 degrees both vertically and horizontally. This assembly includes a robust steel bracket, a cast-mounting base, and options for flange installation, ensuring versatile mounting solutions. The horn's weather-resistant, non-glare matte black foam construction is designed to resist resonance, while the bracket assembly is finished with durable epoxy for long-lasting performance.

Ideal for a range of applications, the BIA-100 bi-axial horn delivers exceptional sound dispersion and audio efficiency when paired with medium or high-powered compression drivers. Its exponentially-flared projectors effectively eliminate phase cancellation and control low-frequency roll-off, making it perfect for professional voice, music, and signaling systems. Suitable for both surface and flange mounting, this horn is an excellent midrange component for two and three-way high-fidelity loudspeaker systems.

Constructed for durability, the weatherproof horn bell is made from non-resonant molded foam with a textured black finish, making it suitable for permanent or portable installations. Whether in houses of worship, recreation and sports centers, mass transit terminals, or industrial, commercial, educational, and institutional facilities, the BIA-100 offers reliable performance. The steel mounting bracket and cast installation base provide adjustable flexibility in sound focusing, ensuring optimal audio delivery in any setting.
