High-performance commercial loudspeaker designed for indoor and outdoor installations. Features coaxial two-way drivers, wide 135° coverage, IP55 weather resistance, and a secure QuickHold mounting system. The Bose Professional DesignMax DM5SE loudspeaker has been engineered to deliver consistent, high-quality sound in demanding commercial environments. Rich low frequencies and clear, intelligible highs are produced through a coaxial two-way design, ensuring balanced audio performance without the need for external DSP or equalization. A wide frequency response and broad conical coverage are provided to maintain uniform sound distribution across the listening area.

A durable, surface-mount enclosure has been designed for both indoor and outdoor use, supported by an IP55 environmental rating that allows reliable operation in wet locations. A refined aesthetic has been achieved through minimal-bezel grilles and discreet branding, allowing the loudspeaker to blend seamlessly into a wide range of architectural styles. Installation time is reduced through a hidden QuickHold U-bracket system, providing fast, secure mounting while minimizing visual clutter.

Key Features 

Coaxial Two-Way Driver Design
A 5.25-inch woofer and a 1-inch coaxially mounted tweeter are used to deliver full, natural sound with precise alignment. Improved phase coherence and clarity are achieved across the listening area.

Dispersion Alignment System
Consistent room coverage is ensured by matching the dispersion pattern of the woofer to the tweeter. A uniform listening experience is maintained, even in acoustically challenging spaces.

Outdoor-Rated IP55 Construction
Reliable performance in outdoor and wet environments is supported by an IP55 rating. An aluminum grille and weather-resistant input cover are included to prevent corrosion and environmental damage.

QuickHold Mounting System
Installation efficiency is improved through a patented QuickHold mounting system. Reduced strain and faster alignment are achieved, lowering the risk of damage during installation.

Design Flexibility
Elegant enclosures, paintable grilles, and removable logos are provided to ensure visual compatibility with diverse commercial interiors and exteriors.

System Scalability
Integration with other DesignMax loudspeakers is supported, allowing system designs to be scaled from small rooms to large venues using a consistent sonic and visual signature.
