Why do you need a diffuser? A good question, and one of the most forgotten and yet important aspects to achieving a great sound from any audio system.

A simple and very effective room treatment system
Our 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). It makes this a highly effective and compact diffuser.
Working Range
Our diffuser models model have 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 (Natural sound) reproduction is the goal. Opera’s – studio’s etc… all use diffusers for correct & natural sound. The human voice for example is very clear & very good audible without any false “ringing” in the room. It increases separation of the instruments and create better space, more detail and a much more natural acoustic environment.
