VersaTune Low Frequency (VTLF) is an extraordinarily low-frequency absorber, with bass trap style performance at 80 Hz where it removes 85% of reflections while limiting absorption in the high frequencies, all in a slim 2-1/8" thick panel. The result is removing hard to treat low frequencies without over-absorbing the bright higher tones. A broad low frequency tuned fiberglass acoustical wall panel that mounts directly to the wall or ceiling, no airspace required. No heavy wood substrates makes for easy installation. Available with a square edge treatment and sizes up to 4' x 10'. Tune any space by pairing with VersaTune and TAD panels for frequency wide absorption.
