Bose Professional ArenaMatch Utility AMU105 Outdoor Speaker (Black)

The Bose 811433-0110 is an ArenaMatch Utility AMU105 outdoor speaker that brings professional-grade sound to open-air venues where music, announcements, and crowd noise all compete for attention.

A 5.25 inch high-excursion woofer partners with a constant directivity horn that covers 100 degrees by 100 degrees, so every listener across the seating bowl, patio, or walkway hears the same balanced mix. The system plays from 90 Hz to 16 kHz, giving bass lines weight while keeping vocals intelligible and cymbals clear.

Weather can be unpredictable, yet the AMU105 keeps performing. Its IP55 enclosure resists rain and dust, the stainless steel grille will not rust, and the industrial grade coating shrugs off UV and salt spray. That toughness makes it a dependable choice for year round installations in stadiums, resorts, and waterfront venues.

Integration is straightforward. The cabinet is compact and lightweight, and a multi-tap transformer for 70 or 100 volt systems is already on board with a bypass tap for low-impedance wiring. Contractors can mount the unit under eaves, to light poles, or along railings without heavy rigging or additional hardware.

Pair the AMU105 with Bose Professional amplifiers and signal processing to access factory presets that protect the drivers and streamline commissioning. Once in place, the speaker delivers consistent, engaging sound that keeps guests listening and venues sounding their best.
