The Bose Professional ArenaMatch AMU105 compact loudspeaker is designed for outdoor and indoor installations where powerful, intelligible sound is required from a discreet enclosure. High-performance audio is delivered through a two-way transducer design that supports clear vocals and balanced music reproduction, even in challenging environments. Wide and consistent 100° × 100° coverage is provided, making the loudspeaker well suited for distributed sound systems and smaller venues that demand uniform listening experiences.
Installation flexibility is supported through weather-rated construction, multiple mounting options, and integrated 70/100V transformer functionality with an 8-ohm bypass. Reliable performance is maintained across hospitality, commercial, and public venues, while compatibility with Bose Professional electronics allows simplified system design and consistent sound quality. The AMU105 is positioned as a compact solution where durability, clarity, and system scalability are required.
Key Features
Two-way transducer design
A high-excursion low-frequency woofer and a high-frequency compression driver are combined through a passive crossover with optimized filters. Balanced frequency response and consistent clarity are achieved across speech and music applications.
Wide and even sound coverage
A constant-directivity high-frequency horn delivers 100° horizontal and vertical coverage. Sound distribution is maintained evenly across listening areas, reducing hot spots and drop-offs.
Outdoor-ready weather protection
An IP55-rated enclosure is used, supported by a three-layer stainless steel grille, water-resistant woofer, industrial polyurethane coating, and a molded input-panel cover. Long-term reliability is supported in exposed outdoor environments.
Integrated 70/100V transformer with bypass
A weather-sealed internal transformer is included with selectable tap settings. An 8-ohm bypass allows use in low-impedance live sound systems without additional hardware.
Flexible mounting and suspension options
Stainless-steel U-bracket mounting is supported through M8 threaded inserts. Compatibility is provided for surface-mount, pan-and-tilt, single-point suspension, and pole-mount accessories.
Compact and durable cabinet design
Exterior-grade plywood construction is used, along with rust-resistant suspension points. Structural integrity is maintained while keeping the enclosure unobtrusive.
Optimized system integration
Factory-tuned loudspeaker presets are available when paired with Bose Professional amplifiers and processors. Faster configuration and predictable performance are supported across installations.
Stocked availability and design flexibility
The AMU105 is offered as a stocked product with no custom-order requirements and is available in black or white finishes to suit architectural aesthetics.
