AcousTech™ low frequency panel was designed to absorb low frequencies without removing high frequency energy from the space.
Their outward appearance resembles a standard panel while all models feature a damped, select-tuned membrane resonator inside that is extremely effective at absorbing sound energy below 150 Hz.
These low frequency acoustic panels can be installed individually or together as a grouping. In addition, the facings of these panels are tackable.
