Sound Diffusers

Shop sound diffuser panels from GIK Acoustics, part of our acoustic panels hub. Diffusers scatter sound reflections rather than absorbing them, and this page includes GIK's GridFusor, SlatFusor and Evolution PolyFusor polycylindrical diffusers, Q7D and Q11D quadratic residue diffusers and the Gotham primitive root diffuser.

Diffusers and Hybrid SlatFusor Panels

Alongside dedicated diffusers, this page carries the GIK SlatFusor Acoustic Panel, described as combining absorption and diffusion, plus the SlatFusor Bass Trap Panel and SlatFusor Corner Bass Trap. For dedicated low-frequency control, see our bass traps.

What is a sound diffuser panel?

A diffuser is an acoustic panel shaped to scatter sound reflections across a room instead of absorbing them. The models here use quadratic residue, primitive root and polycylindrical designs.

What's the point of using a diffuser?

Diffusers help manage reflections while keeping a room from sounding overly "dead," which is why they're often combined with absorption panels in listening rooms and studios.

Diffuser or absorber: which do I need?

Absorbers reduce reflections and echo, while diffusers spread them out; many rooms use both. The SlatFusor Acoustic Panel is described as combining the two approaches.

Do sound absorbing panels really work?

Acoustic panels are designed to reduce echo and reflections, and results depend on room size, panel type and placement. Browse absorption options on our acoustic panels page.
