Acoustic data

Absorption of the mid and high frequencies

Foamly Rectangle reduces reflection energy in the mid and high range, helping cut reverb and improve sound clarity. The source curve covers 630 to 4000 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: 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. The 50 × 100 cm format

    The rectangular module can be oriented vertically or horizontally, which makes covering larger surfaces easier.

  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.

Proste prostokąty, ale robią robotę i echo w pokoju wyraźnie odpuściło. Lekkie, łatwy montaż. Dorzucony klej trzymał słabo, użyłem własnej taśmy montażowej

Simple rectangles but they do exactly what I wanted, the room sounds way less echoey now. Super light, stuck them up alone in minutes and the packaging was spotless.

Klassische Rechteckform, aber sauber verarbeitet und federleicht, an der Wand hinter dem Schreibtisch klingen die Höhen jetzt klarer, kein Halleffekt mehr beim Streamen.

FAQ

Frequently asked questions

The sources describe effective absorption of mid and high frequencies. The curve in the Acoustic data section covers 630-4000 Hz; this shouldn’t be used to promise bass-trap-like performance.

The 50 × 100 cm format equals 0.5 m² of front surface. The calculator uses this value as a starting point.

You can use mounting adhesive, which is not part of the set, or choose self-adhesive tape as an extra option. You’ll find the details in the Installation section.

Yes, but there are only two color price levels. Basic – Graphite is the cheaper base variant, and all other colors share one higher price.
