Bose Professional DesignMax DM3C 3.5" 30W In-Ceiling Loudspeaker - White

A Complete Loudspeaker Assortment to Fulfill Any Design

DesignMax loudspeakers offer the flexibility and refined aesthetics required to deliver exceptional audio performance across a wide range of commercial environments. With multiple form factors available — including ceiling-mounted, surface-mounted, and outdoor-rated models — it’s easy to create a cohesive DesignMax system tailored to your application. The DM3C provides an ideal balance of size and output, making it well suited for background and foreground music applications in retail, hospitality, offices, and other commercial spaces.

Hear The Difference

The DM3C features a coaxial two-way design with a 3.5-inch woofer and 0.75-inch tweeter mounted within Bose Professional’s Dispersion Alignment system. This architecture ensures consistent coverage by matching the woofer’s dispersion pattern to the tweeter’s performance, resulting in clear, intelligible highs and impressive low-frequency extension for its size. With a 75 Hz – 20 kHz frequency range and 30-watt power handling, the DM3C delivers full-range sound without requiring additional EQ or DSP.

See The Difference

Designed with premium aesthetics in mind, the DM3C features a sleek, low-profile grille with minimal bezel for seamless integration into modern interiors. The white finish blends cleanly into most ceiling designs, making it ideal for environments where visual impact must remain subtle. For applications requiring a darker aesthetic, optional black accessory grilles are available separately. Grilles are paintable to match custom design requirements.

Feel The Difference

Installation is streamlined with the patented QuickHold mounting system. Simply insert the loudspeaker into the ceiling cutout and the QuickHold mounting arms automatically engage, temporarily holding the loudspeaker in place. This hands-free design reduces installer strain and allows both hands to remain free for wiring and final fastening, improving efficiency on the job site.

From system design to final installation, the Bose Professional DesignMax DM3C combines acoustic performance, consistent coverage, and refined aesthetics to deliver a reliable, high-quality commercial audio solution.
