Soften Box Panels

With Soften Box Panels, you can create a striking, sound-absorbing surface tailored to your exact dimensions. Choose a subtle, single-colour look or create a more vibrant and dynamic composition by combining different colours and sizes. All Box Panels are manufactured with Class A sound absorption.

The simplest installation method uses the built-in hook-and-loop fastening. The panels can also be mounted using screws, nails, or an optional cleat mounting system.
