Vincent Brient just sent some exclusive photos of the Totaldac listening room showing the acoustic treatment. Diffusers and absorbers are used to achieve the best room acoustics. The diffuser positions between the speakers are custom-made, made of wood, and painted black. Most absorbers are located on the ceiling, far away from the speaker, and far away from the listener.

The graph shows the reverberation time measured with 3 different methods, showing the flat frequency and a 0.3s reverberation time as needed for a 60 square meter room.
