How it works

Some rooms have one stubborn bass note that booms no matter what. The M25 is built to order for exactly that note: a sealed panel whose front face soaks up the problem frequency and leaves everything else untouched.

What makes it different

  • Targets the specific note that is causing trouble, not the whole range.
  • Slim enough to fit rooms where big corner traps will not.
  • Invisible in use — it looks like any other felt-faced panel.

What we need from you

A short measurement of your room, or a visit from us to take one, plus the room dimensions. From that we identify which notes are actually causing the problem and build each unit to match.
