The DS3 Dodecahedron Speaker is minimized in weight while providing maximum performance and long-term stability. With only 7.5 kg and a typical sound power level of 121 dB, the DS3 is most suitable for use on site. The high-performance dynamic driver frames are made of solid aluminum. This provides efficient heat dissipation and hours of level stability. The robust protective grilles prevent damage to the membranes under tough transportation and working conditions. Using the DS3 as a reference sound source provides precise measurement results.
