"TETRA" is a high-performance sound-absorbing panel made of soft polyurethane foam and natural wood - American walnut / oak veneer. TETRA panels are used in acoustic treatment of home studios, professional recording studios, listening rooms, offices, meeting rooms, announcers and vocal booths. Thanks to resonant chambers, sound waves are dispersed, reducing reflection and subsequent reverberation, as well as absorbing echo and other annoying noises. The main advantage of the TETRA acoustic panel is its ability to effectively absorb frequencies from 250 Hz due to vibration vibrations of wooden elements of the structure, which are on a "soft" PPU substrate. Due to the simplicity and ease of installation of our panels it is possible to perform independent installation. Sound absorption coefficient: 0.5 Operating frequency: from 250Hz Purpose: Absorption of MF and HF Substrate density: 25 kg/m3 Height: 100cm Width: 50cm Depth: 6cm Weight:4kg
