I am tweaking my room with bass traps and like the look of this diffuser for the back wall (one each side) with the idea of widening the sound of my narrow room.Has anyone had first hand info of the use of this product??
it would be helpful to include a link - the easiesr you make it for people to respond to you, the more responses you will likely get Primacoustic Acoustic Solutions

it looks like an N17 QRD - but im confused why they say "based on a primitive root sequence" vs "based on quadratic residue sequence". someone should really notify their editors
placement of diffusers and such is dependent upon the acoustic room model you wish to emulate (eg, the room's total specular response you wish to achieve).
with QRDs you will need multiple periods (units arranged together into an 'array') to perform as intended. would be best directly behind the listening position. what is the distance from the listening position to the rear wall? how many were you looking to purchase?
