cerasonar 4050 concept

The cerasonar concept series is an optimal solution for music playback or background
sound in wet rooms such as wellness spas or bathrooms. The installation of the sound panels is
realized during drywall installation and they are placed in the required position instead of the
plasterboard itself. A special dsp amplifier is not required.
