Bose Professional ArenaMatch Utility AMU108 Compact Outdoor Loudspeaker with 8" Woofer (Each)

The Bose Professional ArenaMatch Utility AMU108 is a compact, high-performance loudspeaker designed for indoor and outdoor installed sound applications that demand powerful output and precise coverage from a small-format enclosure. Built for flexibility, it delivers strong vocal clarity and musical definition in distributed and small- to mid-sized sound systems across a wide range of commercial venues.

The AMU108 features a two-way design with a constant-directivity high-frequency horn and an 8-inch high-excursion woofer, providing wide, controlled coverage and extended low-frequency performance. An integrated 70/100V transformer with an 8-ohm bypass supports both distributed and low-impedance systems, making it suitable for background music, foreground music, and live sound reinforcement.

With an IP55-rated enclosure, corrosion-resistant hardware, and multiple mounting options, the AMU108 is engineered for reliable long-term operation in exposed outdoor environments and demanding indoor installations. It integrates seamlessly with Bose Professional amplifiers, processors, and accessories for simplified system design and deployment.
