Primitive Root Diffusers are used to soften harsh wall reflections and make your room ‘sound’ larger then it is. They are defined by prime numbers for a true diffuse reflection. Most commercially available off the shelf PRDs only go up to prime 97 and are too shallow and/or lack the dimensions to affect all frequencies. So I need one that actually works, covers my rear wall and has a wide 250Hz-7000Hz bandwidth. Let’s write some software to mathematically design a huge PRD 2971 according to the specs I need.
