Bose Professional ArenaMatch Utility AMU208 Compact Loudspeaker (Each)

Bose Professional ArenaMatch Utility AMU208 is a loudspeaker designed for indoor and outdoor commercial installations. It enables sound reinforcement and voice reproduction for system designers and integrators, supporting distributed and small- to mid-sized audio systems. This makes it ideal for public venues and shared spaces where consistent coverage and environmental durability are critical.

The loudspeaker operates using a two-way transducer system with passive crossover networks and a constant-directivity high-frequency horn. It supports low-impedance operation as well as distributed systems through an internal 70V and 100V transformer with selectable taps and bypass. The enclosure and components are engineered to maintain functional operation when exposed to weather and environmental conditions.

The system supports applications requiring compact form factors with controlled coverage in fixed installations. It is suited for hospitality, sports, worship, and public environments that require flexible mounting and orientation options. The design allows integration with compatible amplification and processing systems for predictable system behavior.
