RPG Modffusor


The Modffusor represents the evolution in architectural acoustics toward aperiodic sequencing of asymmetrical shapes . The Modffusor is a furniture grade, natural wood sound diffuser designed to provide a more uniform sound field through mid and high frequency sound diffusion while limiting the amount of sound absorption.


Standard Panel Dimensions (mm): 600x600 and 1200x600

Thickness: 230mm







To minimize the lobing inherent in number theory sound diffuser designs, which compromises the uniformity of the scattering, RPG developed the Modffusor. The computer optimized Modffusor offers significantly better performance than its predecessor, the QRD 734, and in a shallower profile. Where the performance difference advances further is when multiple units are installed in an array. An optimized, modulated sequence of an array can take advantage of the aperiodic, asymmetric shape of the Modffusor to minimize lobing effects that are caused by symmetrical and periodic shapes. In contrast to a QRD periodic array, a Modffusor aperiodic array is formed by following the prescription of an optimal binary sequence, which indicates when to use the asymmetric base shape (zero) or the rotated unit (one). The Modffusor is available in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces. It is designed to fit into a standard, reinforced T-Bar grid; more often, it is flush mounted to a wall or ceiling with the included mounting cleat.


  • Offers broad bandwidth sound diffusion in a decorative, wood cabinet.
  • Multiple unit arrays can be sequence optimized for further improvement in scattering.
  • Comes in a variety of finishes, including wood veneer, laminate, melamine and custom paint colors.
  • Simple installation with included mounting cleat.
