Description

MLS Acoustic Diffuser

MLS (Maximum Length Sequence) diffusers scatter incident sound evenly in time and space using a binary well-depth sequence derived from number theory. They convert harsh reflections into a diffuse sound field, improving brightness and spaciousness without deadening the room.

  • MDF body with wood veneer and eco paint
  • 600 × 600 mm module, 50 mm thickness

Frequently asked

Where should MLS diffusers go?
Rear walls and first-reflection side walls of control rooms and listening rooms are the classic positions.

Can they combine with absorbers?
Yes — diffusers and absorbers alternate well; we help set the ratio from your room mode analysis.

Is a fire-rated version available?
Fireproof-board substrate and fireproof finishes are standard options.
