A lightweight diffuser panel from Sonitus Acoustics, made of hard expanded polystyrene. Each panel is 60 x 60 x 15cm, and this pack contains three.

Sonitus says its diffusors disperse sound in your room so you get similar sound energy in all parts of the room. It adds that diffusors are often used in home cinemas to give all listeners the same sound field.

Sonitus Acoustics lists this panel as the Bigfusor.

Why you will love it

Spreads sound around the room

Diffusors scatter sound rather than soak it up. Sonitus says this helps give a similar sound field at different listening positions.

Light enough for walls and ceilings

The panels are made of hard expanded polystyrene. Sonitus says their low weight makes them easy to install on walls or ceilings.

Sonitus recommends non-aggressive adhesives or silicone for installation.

Is it right for you?

A great fit if you…

Want to even out the sound field in a home cinema or listening room
Need a lightweight panel for walls or ceilings
Want a diffuser rather than an absorber

Worth knowing

A diffuser scatters sound and does not absorb it, so pair it with absorbers if you also need to reduce reflections
It comes as a pack of three

Build your system

Diffusion works alongside absorption in a treated room.

Bass control: Add a Sonitus Acoustics Big Trap
Wall absorbers: Add a Sonitus Acoustics Leviter Shape 8
