These Sound Absorption Panels provide the ideal space for casual listening, mixing, mastering, and live monitoring. Made with high-quality Mineral Rockwool of 45kg/m3 density and a maximum absorption rate (NCR) of 1.0. They functions as broadband absorbers, delivering a nice absorption from your 'LOWs' to 'HIGHs'. These absorbers will tackle those early reflections when put on the sidewalls, and nicely annihilate fluttering echoes between opposite walls. Neatly hand-crafted with a unique presence that fits in any setting.
