The Optistep is a 1-dimensional sound diffuser developed to expand the product line anchored by the classic QRD 734 – the first product of its kind offered on the market. With its unique design which does not rely on the traditional dividers between each well, the Optistep has been designed to offer optimal diffusion bandwidth, while the natural wood construction of the unit limits the amount of sound energy that is removed by absorption.
The Optistep is available in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces.
The Optistep is flush or cavity mounted to walls and ceilings with provided blocking.

To minimize the lobing inherent in traditional sound diffuser designs, which compromises the uniformity of the scattering, RPG developed the Optistep. The Optistep offers significantly better performance due to it’s large sequence of element depths. 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 Optistep to minimize lobing effects that are caused by symmetrical and periodic shapes. In contrast to a QRD periodic array, an Optistep 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 Optistep 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.
