Measuring 437mm wide x 531mm high x 704mm deep and weighing 40Kg, the MSUB15 is the same width as the GEO M10 main cabinet, and 50% higher. Cabinets are constructed from Baltic birch ply with large composite bumpers on the corners, and feature integral rigging. Employing a single 15″ diameter / 3″ voice coil Neodymium driver in a high-efficiency band pass cabinet design with a quadratic shaped profiled port, the MSUB15 can be deployed in Omni or Cardioid modes and is available in black, white or custom RAL colours. The touring version features a steel front grille and Speakon connectors (front and back).
