Quadratic Residue diffuser ‘QRD’. 8inch deep wells, based on prime 17. Eliminates flutter echo and standing waves. Ideal for recording studios, home theaters & listening spaces.
The Ultracoustic Z-17 is a high performance quadratic residue diffuser (QRD*) based on prime no. 17. The wells are precisely calculated to break up the acoustic energy and scatter it across and create a diffusive field.
Unlike light-weight plastics that are unable to control powerful low frequencies, the Z-17 QRD combines heavy slats with a grade of solid rubber wood laminate surround for added mass and rigidity. The 24 x 48 Z-17 QRD is made up with a series of 17 deep, narrow wells that effectively diffuser energy from 800Hz to over 10KHz with excellent scattering down to 400Hz.
This makes the Z-17 QRD diffuser particularly effective in variants of the LEDE (live-end, dead-end) studio control room designs where several units of Z-17 are typically clustered across the rear wall, spanning the width of work surface.
The Ultracoustic Z-17 QRD acoustic diffuser can be used in recording studios, home theaters, control rooms, broadcast studios, live rooms where a range of instruments and voices are recorded, rehearsal rooms, auditoriums and other performance spaces.
