The Meyer Sound MUB-X40 U-Bracket is a heavy-duty, professionally engineered rigging accessory designed for secure and flexible loudspeaker mounting. Specifically crafted to accommodate a single ULTRA-X40 wide coverage or ULTRA-X42 controlled coverage point-source loudspeaker, this robust steel bracket simplifies fixed installations and mobile production setups. Its intelligent geometric frame allows audio technicians to safely mount the speaker to a wall or ceiling, or place it flat on a stage floor to serve as a low-profile front fill. The hardware configuration supports both vertical and horizontal speaker orientations, offering precise directional control to optimize acoustic coverage within theaters, houses of worship, corporate lecture halls, and live concert venues.

To ensure a seamless and safe integration workflow, the comprehensive hardware kit includes two heavy-duty M8 threaded bolts, two ergonomic M8 tightening knobs, and a specialized M20-to-M8 (35mm) thread reducer. This reducer converts the cabinet’s integrated bottom pole-mount socket into a safe M8 point, allowing the bracket to lock firmly into the loudspeaker chassis without risking structural slipping. Beyond basic wall and ceiling attachment, the bracket can be paired with an optional 35mm pole-stand adapter to facilitate stable horizontal pole-mounting on traditional speaker stands. Finished in a tough, scratch-resistant coating that matches the premium multi-ply birch enclosures of the ULTRA series, this essential rigging tool ensures compliance with rigorous live-sound safety standards while maintaining a clean, unobtrusive visual profile.
