Bose | DesignMax DM3SE (1-Pair)

• With coaxial two-way drivers, the 30-watt Bose Professional DesignMax DM3SE loudspeaker offers clear, intelligible highs and surprising low end for their size — along with premium aesthetics that complement any commercial sound installation. The DM3SE features a two-way 3.5-inch woofer and 0.75-inch coaxial tweeter mounted within the Dispersion Alignment system, delivering a frequency range of 75 Hz – 20 kHz. The DM3SE is surface-mounted, IP55 outdoor-rated, and locks onto a hidden QuickHold U-bracket for fast, secure installation.

• Combine DesignMax models to complete any design, big or small — 12 loudspeakers to mix and match, from 2-inch, low-profile models to 8-inch, high-SPL compression-driver loudspeakers and outdoor-rated options

• Deliver clear highs and surprising low-end for their size with coaxial two-way drivers — no DSP or EQ required. For even better sound, combine with select Bose Professional DSPs and amplifiers to enable Bose Professional loudspeaker EQ and SmartBass processing, which expands performance and response at any listening level

• Ensure a consistent listening experience throughout the room with the Dispersion Alignment system, which matches the coverage of the woofer to the pattern of the tweeter

• Blend with any room design with elegant form factors, minimum-bezel grilles available in black or white, and removable logos

• Reduce installation time with the patented QuickHold mounting system, which also reduces strain, hassle, and the chance of product damage

• Install easily with industry-standard accessories — all models include Euroblock connectors; in-ceiling models include plenum-rated backcans, tile bridges, and front-access audio wiring that makes installation and troubleshooting easier

• Install DM3SE outside — IP55 rating with standard aluminum grille for outdoor use
