Acoustic data

Absorption of the mid and high frequencies

Foamly Prism reduces reflection energy in the mid and high range, helping cut reverb and improve sound clarity. The source curve covers 250 to 4000 Hz.

α = 0,98at 1000 Hz

  • helps reduce reverb and harsh reflections in the room,
  • 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.

Curve data: 250 Hz - 0.12; 315 Hz - 0.15; 400 Hz - 0.20; 500 Hz - 0.35; 630 Hz - 0.55; 800 Hz - 0.75; 1000 Hz - 0.98; 1250 Hz - 0.94; 1600 Hz - 0.86; 2000 Hz - 0.95; 2500 Hz - 0.90; 3150 Hz - 0.97; 4000 Hz - 0.98. The chart lists 23°C and 48% relative humidity; the sources state no standard or measurement method.

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.

  1. Slanted planes

    The prismatic relief creates dynamic light and shadow and bold 3D geometry.

  2. An open-cell structure

    High-quality polyurethane foam absorbs waves in the mid and high frequencies.

  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.

  4. The mounting surface

    The panel can be mounted with mounting adhesive, which is not included, or with optional self-adhesive tape.

Dimensions and prices

A fixed 50 × 50 cm format

Relief 3D faktycznie robi wrażenie i lekkie to jest niesamowicie. Wysokie tony mniej kłują, choć na bas oczywiście nie ma wpływu.

Le relief 3D est vraiment chouette, ça donne du caractère à la pièce. Léger, facile à coller et les aigus sont mieux tenus.

The 3D relief looks fantastic in person, way more interesting than flat panels. Stuck them up in minutes and the high-end harshness in the room is gone.
