Bose Professional AM40 ArenaMatch 14" Outdoor Array Loudspeaker with 40° Vertical Coverage - Each

Bose Professional AM40 ArenaMatch 14" Outdoor Array Loudspeaker with 40° Vertical Coverage - Each

The Bose AM40 is a premium outdoor loudspeaker designed for large-scale venues where powerful, clear, and consistent sound is critical. Whether it’s a stadium, arena, or outdoor entertainment space, this speaker delivers reliable high-output performance with intelligent coverage control. Its 40° vertical dispersion, robust construction, and compatibility with the Bose ArenaMatch system make it an ideal solution for demanding sound reinforcement applications.

Designed for Demanding Outdoor Venues

Engineered to perform in open-air environments, the AM40 is built with a 14-inch neodymium woofer and six titanium-diaphragm compression drivers. This configuration supports high sound pressure levels and clean vocal projection, making it suitable for both music and speech. The enclosure is made of exterior-grade birch plywood, coated in industrial polyurethane for durability, and sealed with a triple-layer stainless steel grille for protection against water, dust, and debris. Its water-resistant woofer cone and IP55 rating allow it to function reliably even in harsh weather conditions.

Consistent Coverage with DeltaQ Technology

The Bose AM40 features Bose’s DeltaQ array technology, which allows each module to adjust its directivity to better match the audience area. By controlling the angle and focus of the sound, DeltaQ provides improved clarity, even coverage, and reduced spill into unwanted zones. This makes it easier to maintain intelligibility across large or irregularly shaped venues, all while minimizing the number of modules required in a system.

Customizable Horizontal Dispersion

To adapt to a variety of venue layouts, the AM40 offers three interchangeable horizontal coverage options:

• AM40/60 - 60° horizontal waveguide
• AM40/80 - 80° horizontal waveguide
• AM40/100 - 100° horizontal waveguide

These waveguides are replaceable, allowing for on-site adjustments based on the installation’s unique requirements. Users can also form asymmetrical patterns to accommodate complex left-right array configurations or address non-uniform seating areas.

Performance That Scales With Your Needs

This loudspeaker supports both bi-amp and passive modes and includes transformer taps for use in 70V and 100V distributed systems. It handles up to 750 watts continuously in passive mode and peaks at 3000 watts, providing strong headroom for dynamic program material. The Bose AM40 produces up to 127 dB of maximum SPL depending on waveguide configuration, with a frequency range extending from 55 Hz to 18 kHz. Sensitivity and output remain consistent whether used in passive or bi-amp configurations, making it flexible for a variety of system designs.

Fewer Modules, Lower Costs

The wide vertical dispersion of the AM40 helps reduce the number of speakers needed in an array, minimizing visual clutter and installation complexity. It can also be combined with 10° and 20° vertical coverage models in the ArenaMatch family, allowing sound system designers to create arrays that match the venue’s shape and size without compromising tonal consistency. Since all models use the same transducers, the tonal balance across mixed arrays remains uniform.

Certified for Safety and Integration

The Bose AM40 is EN 54-24 certified for use in voice alarm systems, making it suitable for public venues that require fire and emergency communication compliance. It integrates seamlessly with other Bose Professional products, including ArenaMatch Utility speakers for zone fill, PowerMatch amplifiers for scalable power, and ControlSpace DSP for detailed signal processing. Presets for ControlSpace Designer software help simplify tuning and reduce setup time in complex installations.

Flexible Mounting and Accessory Options

Installation is straightforward, thanks to M12 threaded inserts that support a wide range of rigging options. The speaker is compatible with optional accessories such as U-brackets, array suspension kits, and additional waveguide kits. These components allow for flexible mounting and alignment while ensuring secure and durable deployment in permanent outdoor setups.

The Bose AM40 is a purpose-built loudspeaker for professional outdoor applications where clarity, coverage, and weather resistance are non-negotiable. Its modular design, high power capacity, and system integration features make it a reliable choice for venues that require scalable, efficient, and high-quality sound coverage.

FAQs

1. What makes the Bose AM40 different from 10° and 20° modules? The AM40 offers a wider 40° vertical coverage, making it ideal for point-source use or for reducing the number of modules in an array, while still allowing integration with 10° and 20° models for customized designs.
2. Can I customize the AM40's horizontal coverage? Yes, the AM40 supports 60°, 80°, and 100° horizontal waveguides that can be swapped out to suit the venue's layout and coverage needs.
3. Does the AM40 support both bi-amp and passive modes? It does. The loudspeaker can operate in either mode and also includes 70V and 100V transformer inputs for compatibility with distributed sound systems.
4. Is the AM40 weather-resistant? Yes, the speaker is IP55 rated and features a weather-treated enclosure, triple-layer grille, and water-resistant woofer coating to withstand direct outdoor exposure.
5. What accessories are available for the AM40? A range of accessories is available, including U-brackets, suspension kits, and waveguide kits, allowing for flexible mounting and on-site adjustment.
