Description for Sample set of all flame-retardant Speaker Cloths
With the new Speaker Cloth FR, you can easily fulfil the fire protection regulations for publicly accessible buildings and the corresponding tender requirements. This was virtually impossible with the acoustically transparent textiles previously available on the market.
Better than fire protection class B1: Speaker Cloth FR combines optimum preventive fire protection with the excellent acoustic properties typical of all cover fabrics from Speaker Cloth.com. The fabric has been certified by the French test institute FCBA in accordance with the demanding French standard NFP 92503 M1 and EN 13773-1. It therefore even exceeds the requirements of DIN 4102 B1, which is standard in Germany: the French M1 classification stands for non-flammable materials such as plasterboard.

There are two sound transparency measurement diagrams for every type of acoustic cloth available from Akustikstoff.com:
Diagram 1 shows the measurement in decibels (dB). It indicates how strongly sound is attenuated across different frequency ranges.
Diagram 2 shows the measurement in dBFS (decibels relative to Full Scale). This is a digital reference measurement that represents the acoustic behaviour in relation to the maximum signal level.
Each diagram contains several curves illustrating the effect of fabric tension (stretching):
- without fabric → reference measurement (open transmission)
- fabric at 0% stretch → unstretched condition
- fabric at 3% stretch → typical installation tension
- fabric at 5% stretch → maximum recommended tension
These measurements demonstrate how minimal the influence of the speaker fabric is on sound reproduction. Even at different tension levels, the sound transparency remains virtually unchanged.
