Bose Professional AMM112 - Multipurpose Loudspeaker

The Bose Professional AMM112 multipurpose loudspeaker is engineered for demanding live sound reinforcement where clarity, consistency, and controlled coverage are required. A passive coaxial two-way architecture is employed, combining a 12-inch low-frequency transducer with a 3-inch compression driver to deliver up to 131 dB peak output. Consistent frequency response and strong vocal projection are achieved across the listening area, making the loudspeaker suitable for performers and audiences in professional environments.

A proprietary Beamwidth Matching Waveguide is integrated to ensure uniform tonal balance through the crossover region, allowing sound to be projected evenly and accurately. The enclosure is designed for both portable and permanent installations, where flexibility is required for mains, monitors, fills, or delay applications. Seamless system integration is supported through matched voicing with other Bose Professional loudspeaker lines, enabling efficient configuration and predictable performance in complex sound systems.

Key Features

High-output coaxial performance
A compact, high-output design is utilized to produce up to 131 dB peak SPL. A shared neodymium magnet structure supports both the 12-inch low-frequency driver and the 3-inch compression driver, allowing powerful output to be delivered with precise phase alignment and clarity.

Multipurpose deployment flexibility
The loudspeaker is designed to be deployed as a main, monitor, fill, or delay source. Extended low-frequency performance can be achieved when paired with compatible subwoofers, allowing bandwidth requirements to be adapted to front-of-house or fill applications.

Consistent system voicing
Matched tonal characteristics are provided to ensure consistency when combined with AM array modules and AMU utility loudspeakers. Time required for system tuning and configuration is reduced, as predictable voicing behavior is maintained across different system designs.

Beamwidth Matching Waveguide technology
Low- and high-frequency beamwidths are aligned through the crossover region, ensuring tonal consistency across the entire coverage area. Clear intelligibility and uniform audience coverage are maintained, even in challenging acoustic environments.

Rotatable coverage pattern
A 110° × 60° coverage angle is provided, with horizontal or vertical orientation made possible by rotating the enclosure. No tools or disassembly are required, allowing fast adaptation to different mounting positions.

Lightweight and transport-ready enclosure
A 22 kg (49 lb) cabinet is constructed with ergonomic handles and a 35 mm pole stand adaptor. Transport, setup, and repositioning are simplified for mobile and touring applications.

Optimized processing and amplification compatibility
Best performance and loudspeaker protection are achieved when paired with Bose Professional PowerMatch amplifiers and ControlSpace DSP. System reliability and audio consistency are maintained under high-output operation.

Versatile mounting and installation options
Deployment is supported in both permanent and portable installations through optional U-bracket and suspension accessories. Seven integrated M10 threaded inserts are provided for custom suspension solutions.

Companion subwoofer integration
A matching AMS115 multipurpose subwoofer is available, featuring a 15-inch transducer, low-frequency extension to 35 Hz, and high peak output. Integrated mounting hardware supports seamless integration into permanent installations.
