Why do you need diffusers ?
A QRD diffuser is an acoustically hard surface which, because of its calculated 3D-design, scatters sound waves that strike it both spatially and spectrally. The diffuser can do this within a targeted working range, usually the range in which fundamental musical tones are found (c4 octave).  
Every model has a practical working range that spans over 4 octaves.  
Our Quadratic residue diffusers (QRD) can be an essential and powerful tool in the acoustic optimization of any room in which high-end sound reproduction is a goal. Opera's - studio's etc... all use diffusers for correct & natural sound (also the human voice is very clear & very good audible without false "ringing" in the room)
