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.

The threaded attachment points used for mounting optional accessories, such as our pan-tilt bracket, have been relocated from the back of the cabinet to the included U-bracket. This change simply requires the use of the U-bracket, as the optional mount will thread into the U-bracket, which is then attached to the loudspeaker cabinet.
Due to these changes, new SKU product codes have been introduced.
