Panel types

Acoustic diffuser & absorber types

Six panel families, one workflow. Pick the type that matches your problem — scattering panels for echo and liveliness, absorbers for boom and boxiness — then design it and cut it tonight.

Diffusers — scatter reflections

1D QRD1D Quadratic-Residue Diffuser (QRD)The classic well-and-fin panel that scatters horizontally.1D PRD1D Primitive-Root Diffuser (PRD)A QRD cousin that suppresses the straight-back reflection.2D QRD2D Quadratic-Residue DiffuserA grid of square wells that scatters in both directions.Skyline2D Skyline DiffuserThe block-city look — a 2-D primitive-root height map.

Absorbers — remove energy

Slat absorberSlat (Slotted) AbsorberWood slats over a damped cavity — tames low-mid boom.Perforated absorberPerforated-Panel AbsorberA drilled panel over a cavity — a tunable mid trap.
