Designed for premium audio performance in compact ceiling spaces, the Bose DesignMax DM2C-LP in-ceiling speakers deliver powerful sound with clean aesthetics for commercial environments. These 2.25-inch, low-profile loudspeakers are built with Bose Professional drivers to offer a wide frequency response from 85 Hz to 19 kHz. With a maximum SPL of 97 dB and 20 watts of continuous power handling, they provide crisp, clear background music or vocal audio in conference rooms, hospitality venues, and retail spaces. The included 70V/100V transformer taps and 16-ohm bypass ensure compatibility with distributed audio systems.

A QuickHold mounting system allows fast, secure installation with reduced strain and minimal risk of damage. These speakers blend effortlessly with any ceiling design thanks to minimum-bezel grilles in black or white, which are also paintable and feature removable logos. Their low-profile backcan design—just 3.9 inches in depth—makes them ideal for installations where ceiling space is limited. Plenum-rated for commercial use and compliant with UL-1480A and CE standards, the DM2C-LP is a reliable choice for interior sound reinforcement.

Key Features:

• Low-Profile Design for Tight Spaces
  With a 3.9-inch (10 cm) backcan depth, these speakers fit easily into shallow ceiling cavities, making them suitable for modern low-clearance installations.

• QuickHold™ Mounting Arms
  Patented QuickHold mounting arms reduce installation time and strain, ensuring a secure fit and minimizing the risk of product damage.

• Custom Bose Professional Drivers
  Engineered drivers deliver high-performance sound without requiring additional DSP or EQ. When used with Bose amplifiers or DSPs, enhanced audio processing becomes available through SmartBass and Bose EQ.

• Versatile Visual Integration
  Minimum-bezel, magnetically attached grilles (paintable and available in black or white) ensure seamless blending with room décor. The logos are rotatable or removable for discretion.

• Wide Compatibility
  Euroblock connectors, front-access wiring, and included tile bridges support fast and flexible installations with industry-standard components.

• Commercial Safety Compliance
  Fully certified for indoor plenum installation (UL-1480A, UL2043) and CE compliant, the DM2C-LP is designed to meet commercial building safety codes.
