Light, easy to mount, and the triangle pattern looks sharp on camera. Took the edge off the echo in my recording space.

Acoustic data
Less reverb in a flexible module layout
Basotect® absorbs sound energy thanks to its open-cell structure. The chart shows curves for 3, 5 and 7 cm thicknesses - the thicker the panel, the more effective the absorption of lower frequencies.
α = 0,57at 315 Hz (7 cm)
α = 0,94at 1000 Hz (7 cm)
α = 0,98at 1600 Hz (7 cm)
- Reducing reflections improves voice clarity in recordings and calls.
- The greater the thickness (from 3 to 7 cm), the better the performance at lower frequencies.
- The triangles let you extend the absorbing surface in multiple directions.
- Greater thickness provides better absorption of low frequencies.
Sound absorption coefficient α
Curves for 3, 5 and 7 cm thicknesses. Conditions: 23°C, relative humidity approx. 48%; range 250-4000 Hz.
Construction
Soft Basotect® cut into a modular triangle
The lightweight absorbing material takes a form that can be combined into many larger figures.
Basotect® foam
The open-cell structure, with a density of approx. 9 kg/m³, absorbs sound.
The Foamly surface
It's soft and pleasant to the touch, so it needs a gentle press.
The triangular shape
The elements can be combined into hexagons, zigzags and geometric mosaics.
Applied color
The prefabricated panel is finished in the chosen color after ordering.
A distinctive surface
Small openings and irregularities, in places also visible under the flocked surface, are a natural feature of the open-cell Basotect® melamine foam, not a product defect.
Dimensions and prices
Two triangle formats, three thicknesses
The color doesn't affect the price; only the size and thickness count.

Ładny geometryczny układ, sam montaż banalny. Echo przy nagraniach mniejsze, choć pianka dość miękka i trzeba uważać przy klejeniu.
