Bose Professional ArenaMatch AMU105 Compact High-Performance Loudspeaker | 811433-0110

The Bose ArenaMatch AMU105 is a compact, high-performance loudspeaker designed for professional indoor and outdoor installations such as stadiums, entertainment venues, restaurants, and public spaces. It delivers powerful, intelligible sound while maintaining a compact and discreet enclosure.

This model uses a two-way driver configuration consisting of a 5.25-inch LF5 high-excursion woofer and a high-frequency compression driver with a 2-inch voice coil, providing clear vocal reproduction and detailed high frequencies.

A 100° × 100° constant-directivity horn ensures wide, even coverage across listening areas, making it ideal for zone-fill applications or foreground music systems. The speaker is IP55 weather-rated, allowing reliable performance in outdoor environments exposed to rain, humidity, and dust.

The AMU105 also includes a built-in 70/100V transformer with an 8-ohm bypass, allowing flexible integration into distributed audio systems or low-impedance setups.
