Bose DesignMax DM12SE 12" Coaxial Wall-Mount Loudspeaker, Single - Black or White
The Bose DesignMax DM12SE is a 12" Weatherized Coaxial Surface-Mount Loudspeaker with 300W continuous power handling, IP55 rating and a bass response reaching down to 38Hz — delivering high-output, full-range sound with consistent clarity and uniformity for indoor and outdoor commercial installation applications.
The Bose Professional DesignMax DM12SE is the largest and most powerful loudspeaker in the DesignMax family — a weatherized, full-range 12" coaxial surface-mount loudspeaker that combines deep bass, high output and consistent 102° conical coverage in a sleek, robust enclosure suitable for both indoor and outdoor installation.
Designed for integrators who need a single speaker solution capable of delivering the output, intelligibility and reliability required across a wide range of demanding commercial environments — including performance venues, places of worship, hospitality spaces, fitness studios, retail stores, nightlife and bar areas, outdoor patios and courtyards, and theatres — the DM12SE provides the flexibility, aesthetic appeal and professional performance that the DesignMax range is known for. Available in black or white to suit any interior or exterior design scheme — please select your preferred finish before adding to basket.
12" Coaxial Point-Source Design for Consistent Coverage
The DM12SE’s coaxial transducer places a 1.4" (36mm) weather-treated compression driver at the acoustic centre of the 12" woofer — creating a true point-source design that delivers consistent, uniform sound across the full 102° conical coverage pattern with no lobing, phase issues or frequency-dependent coverage changes that occur with separated two-way driver configurations. This ensures that every listener within the coverage area hears the same balanced, full-range sound regardless of their position relative to the speaker — particularly valuable in performance venues, worship spaces and hospitality environments where consistent intelligibility and music quality throughout the listening area are essential.
Deep Bass Down to 38Hz
A 12" weather-treated woofer delivers powerful, deep bass response reaching down to 38Hz — providing genuine full-range performance from a surface-mount loudspeaker without the need for a separate subwoofer in most commercial background music and foreground sound applications. With 300W long-term continuous power handling and 1,200W peak handling, the DM12SE has the headroom to handle demanding live performance and high-SPL applications with a calculated maximum SPL of 119dB at 1 metre.
Weatherized for Indoor & Outdoor Reliability
The DM12SE’s injection-moulded engineering plastic enclosure is UV fade-resistant, IP55 rated and designed for reliable operation across an operating temperature range of -25°C to 70°C — making it equally suitable for challenging outdoor environments including exposed patios, courtyards and covered external areas as it is for indoor commercial spaces. The perforated aluminium powder-coated grille features a tamper-resistant design and is paintable to match any interior or exterior colour scheme, and the rotatable Bose logo maintains the correct orientation in any mounting position.
Flexible Mounting & Professional Integration
Twelve M8 threaded inserts — two on top, two on the side and eight on the rear — provide flexible and secure mounting options for a wide range of installation scenarios, and the included rugged outdoor-ready pan/tilt bracket enables fast installation, precise aiming and long-term reliability in permanent installations. Factory-optimised tunings for Bose Professional amplifiers and processors are available, with SmartBass processing and Bose Professional EQ voicing providing enhanced system optimisation when used within the Bose Professional ecosystem.
