Description
Low frequency acoustic trap Low-frequency acoustic filter, specially designed for installation in the corners of the room, producing maximum sound pressure across the entire frequency range. Easy installation using adhesives. Economical and extremely effective in damping the effects of room resonance modes at low frequencies. Made from high density acoustic foam with controlled porosity.
