These two dimensional sound diffusers give a more diffuse distribution of the sound and better compromise between Music and Room, and remove acoustic aberrations such as image shift, coloration and flutter echoes. These diffusers gives a sense of spaciousness to your music (or recording room) by addressing those issues without deadening it too much, the sound in the room doesn't lose any harmonic progression associated with the absorption of the acoustic panel. The diffusers are made of solid wood and are hand crafted with very good dispersion of the sound. They are a work of art and environmentally friendly, also theses pieces can be multiplied to fit any space as the design requires. This set is made to fit in any rear wall of a control room or a cabin.
