Compact, weatherized 5.25″ two-way loudspeaker for outdoor foreground music and clear speech. With a consistent 100°×100° pattern, integrated 70/100V transformer (8-ohm bypass), and IP55-rated enclosure, the AMU105 delivers even coverage and dependable performance on concourses, pool decks, patios, and small venues.

Description

Pack stadium-grade clarity into a compact box. The Bose ArenaMatch Utility AMU105 is a weatherized, two-way loudspeaker that delivers articulate vocals and full, foreground music in outdoor zones where space is tight but coverage has to be wide. A 5.25″ LF5 woofer teams with Bose’s EMB2S compression driver behind a constant-directivity horn, creating a consistent 100° × 100° pattern you can mount horizontally or vertically without hot spots. An internal 70/100V transformer (with 8-ohm bypass) streamlines distributed runs, while the rugged enclosure, three-layer stainless-steel grille, and IP55 rating mean it keeps playing through heat, dust, and rain. Use AMU105 as zone-fill around ArenaMatch arrays, or on concourses, pool decks, courtyards, breweries, and retail promenades where high SPL and speech intelligibility matter day after day.
