Bose Professional ArenaMatch Utility AMU105 Outdoor / Fill Speaker (White)

The Bose 811433-0210 is a loudspeaker from the ArenaMatch Utility line that brings full, intelligible sound to places where weather or limited space often get in the way of good audio. It uses the same acoustic voicing found in larger ArenaMatch arrays, so music and speech stay clear and consistent even when you mix it with other Bose systems.

A 100° by 100° constant-directivity horn spreads high frequencies evenly, so listeners hear the same detail whether they stand directly in front of the cabinet or off to the side. A 5.25 inch high-excursion woofer supports the low and mid-range content that gives voices and instruments their warmth and punch.

With an IP55 rating and a fiberglass-reinforced enclosure, this speaker keeps working through rain, dust, and coastal air. The included stainless-steel U-bracket makes it easy to tuck under an overhang, mount to a pole, or aim toward seating areas along concourses, restaurant patios, pool decks, or theme-park walkways. The white finish helps it disappear against light walls and ceilings, so attention stays on the performance, not the hardware.

Installation remains flexible. An internal transformer offers multiple tap settings for 70 volt and 100 volt distributed systems, while an 8 ohm bypass lets you drive the speaker directly for low-impedance or live-sound rigs. The cabinet handles up to 400 watts peak and delivers 90 dB sensitivity, making it a practical match for Bose PowerMatch and PowerSpace amplifiers.

Measuring roughly 6 by 12 by 9 inches, the ArenaMatch Utility AMU105 fits where larger boxes cannot, yet it still provides the output and clarity needed for background music, paging, or zone fill in performance venues. Whether you manage an outdoor bar, a small stadium section, or a house-of-worship overflow area, this speaker offers a straightforward way to deliver Bose quality in demanding spaces.
