Built for zone-fill coverage or high-SPL foreground music, Bose Professional ArenaMatch Utility loudspeakers offer similar tonal balance to ArenaMatch array modules but in compact designs. They have the same EMB2S compression driver as ArenaMatch arrays, ensuring consistent sound, and the same IP55 weather rating. Deploy them for zone-fill coverage in sports stadiums, arenas, outdoor entertainment centers, and more. Or use them to provide intelligible, high-level sound in any outdoor area — from niche venues such as breweries and fairgrounds to larger settings like resorts and outdoor shopping centers.
The AMU108 is a small-format ArenaMatch Utility model for outdoor applications that require excellent audio from compact loudspeaker. It provides wide, even coverage with a 90° × 60° constant-directivity high-frequency horn, 80 Hz – 16 kHz frequency response, 121 dB peak SPL, and supports the lowest vocal ranges with a Bose Professional LF8 8-inch woofer.
