Bose Professional AMM108 Multipurpose Loudspeaker

Bose Professional AMM108 is a multipurpose loudspeaker designed for installed and portable sound reinforcement applications. It enables sound reinforcement, monitoring, and fill coverage for system designers and operators, supporting live performance and installed audio workflows. This makes it ideal for venues where controlled coverage, portability, and consistent voicing are required.

The loudspeaker operates using a passive, coaxial two-way design with a compression driver and low-frequency transducer coupled through a Beamwidth Matching Waveguide. It provides controlled coverage that can be reoriented by rotating the enclosure to swap horizontal and vertical dispersion. The system is intended for use with external amplification and processing.

The system supports applications requiring a compact enclosure with predictable coverage and output. It is suited for main, monitor, fill, and delay roles in permanent or portable systems. The design allows integration with compatible Bose Professional loudspeakers and amplification platforms.
