RPG Diffractal (Fractal QRD Diffuser)
The Diffractal® by RPG Diffusor Systems offers the broadest spectrum of sound diffusion available today. A nested 1D quadratic residue diffuser (QRD), the Diffractal achieves full spectrum sound diffusion by combining the self-symmetry property of fractals with the uniform scattering of QRD diffusers.
Fractal formations are an elegant way to extend the bandwidth of QRD diffusers. Essentially, the RPG Diffractal contains a set of small QRD diffusers (for high-frequency diffusion) nested inside a large QRD diffuser (for mid-frequency diffusion).
For even better performance, you can mount a set of Diffractal diffusers at different depths (based on fractal self-similarity). This mounting method, called a “fractal modulation”, will expand the diffusion bandwidth further into the low frequency range, while simultaneously improving the mid-frequency performance (by eliminating negative effects caused by periodicity). The result is a 3rd order nested fractal diffuser, for the ultimate in broadband diffusion.
The RPG Diffractal is custom manufactured to order and usually ships in 6-8 weeks. Shipped directly from RPG.
