Bose AMU105 100×100 Outdoor Loudspeaker – Compact, High-Performance Audio for Harsh Environments

The Bose AMU105 Outdoor Loudspeaker with a 100° x 100° dispersion pattern is a compact, full-range solution designed to deliver consistent, intelligible audio in outdoor and indoor environments where durability and clarity are paramount.

With IP55 weather resistance, flexible mounting options, and a rotatable high-frequency waveguide, the Bose AMU105 100×100 is an ideal speaker for sports venues, outdoor shopping centers, transportation hubs, houses of worship, and other environments requiring powerful, wide-dispersion sound in a compact, reliable enclosure.

Rugged, Compact Design for Demanding Installations

Built to thrive in challenging conditions, the AMU105 loudspeaker features a compact, lightweight enclosure made from fiberglass-reinforced composite, engineered to resist moisture, dust, salt, UV radiation, and extreme temperatures. With an IP55 weather rating, this speaker can be installed confidently in permanently outdoor or semi-covered environments.

Its sleek, unobtrusive design allows for seamless integration into architectural spaces, whether mounted under eaves, along beams, or on vertical walls. The robust construction makes it ideal for outdoor installations where long-term performance, low maintenance, and aesthetic discretion are required.

Full-Range Performance in a Small Package

Don’t let its size fool you—the AMU105 is a single 5.25-inch full-range loudspeaker capable of delivering detailed, articulate sound with surprising low-frequency extension for its class. Its frequency response of 80 Hz to 16 kHz (-3 dB) ensures clear vocal projection, accurate music reproduction, and intelligibility even in acoustically challenging spaces.

Whether used for foreground sound or background audio in commercial, recreational, or institutional settings, the AMU105 offers an exceptional balance of output, clarity, and size.

100° x 100° Coverage for Wide Dispersion

The rotatable high-frequency waveguide on the AMU105 provides a wide 100° horizontal by 100° vertical dispersion pattern, ensuring consistent coverage across broad listening areas. This makes the AMU105 perfect for applications where a wide, even sound field is required and speaker count needs to be minimized.

The rotatable design allows installers to maintain optimal coverage regardless of whether the speaker is mounted horizontally or vertically—offering additional installation flexibility in complex or asymmetrical spaces.

Easy Integration with Low-Z and 70V/100V Systems

Designed for flexibility, the Bose AMU105 includes an internal multi-tap transformer that supports both low-impedance (8 ohm) and high-impedance (70V/100V) systems. This enables use in distributed audio systems commonly found in commercial spaces, theme parks, or sports facilities.

The power tap settings can be adjusted via a convenient rear-panel switch and include:

• 70V: 50W, 25W, 12.5W, 6.3W

• 100V: 50W, 25W, 12.5W

• 8-ohm bypass mode

This makes the speaker compatible with a wide range of amplification systems, offering easy integration into new or existing installations.

Quick and Flexible Mounting Options

The AMU105 comes with a factory-installed, heavy-duty U-bracket that allows for versatile mounting on walls, ceilings, beams, or trusses. The bracket supports both vertical and horizontal positioning and is designed to withstand the rigors of outdoor mounting.

Multiple M8 threaded inserts on the enclosure allow for custom rigging or use with third-party accessories. The speaker’s lightweight design—just under 7.3 kg (16 lbs)—makes it easy for a single technician to handle and install.
