Description

Give outdoor zones concert-grade clarity in a compact footprint. The Bose ArenaMatch Utility AMU108 pairs an LF8 8″ high-excursion woofer with the EMB2S compression driver on a rotatable 90°×60° horn, delivering uniform coverage, intelligible vocals, and musical punch for concourses, terraces, worship campuses, and entertainment venues. The weather-sealed 70/100V transformer (with 8-ohm bypass) simplifies distributed runs, while IP55 construction—with a three-layer stainless grille, water-resistant woofer, and molded input cover—keeps the system working through dust, heat, and rain. Factory-optimized presets for Bose amps speed commissioning, and the included stainless U-bracket plus rear M8 inserts make aiming and mounting straightforward. White finish blends cleanly with modern architecture.
