Douro Diffuser is a product designed to provide maximum uniformity to the ambient sound field through high frequency diffusion while the solid wood construction of the unit limits the amount of sound energy that is lost to absorption. The Wave shaped pattern that resembles a tile, guarantees a good diffusion spread. The scattering begins at 400 Hz and offers effective and even diffusion up to 5000 Hz. The premium material used in the manufacturing of this product comes available in 6 colours, matching your preferences and the patterns of your room.
