  • supports clearer speech during conversations, meetings and recordings,
  • tidies up mid and high frequencies in a home studio or listening room,
  • it is not a bass-control solution - the sources describe performance in the mid and high range.

Construction

A lightweight form of open-cell foam

The construction combines the model's geometry with absorbing material and the chosen Foamly color. The panel is flexible, lightweight and dust-free; when carrying it, avoid pressing the soft surface at single points.

  3. The Foamly color

    You choose a variant from the wide palette; Basic - Graphite has a lower price, and the remaining colors share a higher one.

Kwadraty układają się w równą ścianę, wygląda czysto i nowocześnie. Echo przy nagraniach zmalało, a całość lekka jak piórko.

Schlichte Quadrate, machen sich gut im Heimstudio und dämpfen die Höhen merklich. Etwas schade, dass keine Messdaten dabei sind, ansonsten zufrieden.
