STARK Sports absorbent

  • Akustikmiljö STARK Sportabsorbent

STARK improves acoustics and has a rugged wire mesh to protect the absorber. STARK is mainly used in sports centers and in rooms with low ceilings at risk of being damaged. STARK is built for harsh and noisy environments such as sports halls where ball hits and tackles would otherwise damage the sound absorbers. The sturdy wire grid holds the absorbent securely in place. STARK is an effective sound absorber manufactured by EcoSUND consisting of recycled PET.
