Overview

The Dodecahedron Speaker Set, comprising of the DS3 Dodecahedron Loudspeaker and the PA3 Power Amplifier, is the measuring equipment designed for professionals for use in their daily measuring tasks in room and building acoustics. Optimized design, combined with unique precision, low weight and flexible operation establish this equipment as a reference in the marketplace.

The DS3 Dodecahedron Loudspeaker is built from twelve specially-developed dynamic drivers that ensure a uniform emission of the acoustic test signal. The PA3 Power Amplifier supplies an equalized pink noise to the DS3. The combination of PA3 and DS3 thus generate an acoustically-flat pink noise under free-field conditions.

DS3 Dodecahedron Speaker

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 120.5 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.
