Description

The DesignMax DM3SE utilizes a coaxial two-way architecture that nests a 0.75-inch neodymium tweeter directly inside a 3.25-inch woofer. By integrating Bose Professional’s signature Dispersion Alignment system, it matches the acoustic coverage pattern of the woofer to the tweeter, eliminating phase cancellations and acoustic blind spots. It produces an incredibly flat, natural frequency response straight out of the box, removing the strict necessity for external digital signal processing (DSP) or complex equalization adjustments.

Features

  • Dispersion Alignment System: Keeps audio output uniform and time-aligned so the listener enjoys seamless frequency transitions throughout the entire coverage zone.
  • All-Weather Reliability: Built with an IP55 outdoor weather rating alongside an included weather-resistant input cover to guard cabling infrastructure against dust and moisture intrusion.
  • QuickHold Mounting Bracket: Uses an external U-bracket pipeline where the loudspeaker easily slides into place and locks via hidden toolless locking levers, noticeably accelerating mounting times.
  • Premium Architectural Aesthetics: Employs low-profile, minimum-bezel steel grilles in a clean white finish, complete with a removable and rotatable logo badge so the box blends naturally into upscale modern walls.
  • Paintable Finish: The industrial UV-resistant plastic enclosure and front protective grille are fully paintable to match unique property interiors or exterior facades.
  • Distributed System Integration: Equipped with integrated Euroblock connectors featuring loop-through capability, working seamlessly with both high-impedance 70V/100V lines or standard low-impedance 8-ohm setups.

Applications

  • Outdoor Patios & Cafés: Ideal for open-air restaurant terraces, resort pool decks, and hotel balconies.
  • Boutique Retail Spaces: Fits seamlessly into high-end clothing boutiques, showrooms, and shopping mall pathways.
  • Corporate Offices & Boardrooms: Perfect for corporate boardrooms, lobbies, open-concept workspaces, and conference rooms.
  • Transportation & Waiting Lounges: Delivers highly articulate speech announcements across airports, train hubs, and registration lines.
  • Houses of Worship: Functions efficiently as secondary delay fills or main speakers in small-capacity auxiliary spaces.
