Bose Professional ArenaMatch Utility AMU105 Compact Outdoor Loudspeaker with 5.25" Woofer (Each)

The Bose Professional ArenaMatch Utility AMU105 is an ultra-compact, high-performance loudspeaker designed for indoor and outdoor installed sound applications requiring clear, consistent audio from a discreet enclosure. Engineered for demanding environments, it delivers wide, even coverage with strong vocal intelligibility and balanced musical response in a small-format cabinet. Its weather-rated construction makes it suitable for permanent outdoor installations as well as indoor commercial spaces.

The AMU105 features a two-way design with a constant-directivity high-frequency horn and a high-excursion low-frequency driver, providing reliable performance across distributed and small-to-mid-sized sound systems. An integrated 70/100V transformer with bypass allows flexible system design for both distributed and low-impedance applications. The enclosure is built for durability and long-term performance in exposed environments.

Designed to integrate seamlessly with Bose Professional amplifiers, processors, and accessories, the AMU105 supports a wide range of mounting options and installation scenarios. Its compact footprint, robust output, and environmental resistance make it a versatile solution for commercial venues that demand consistent sound coverage and installation flexibility.
