Vogl Wall and Ceiling System

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.

Ceiling and Wall Quadratic Residue Diffuser

AVL’s Prime 7 Quadratic Residue Diffusers are an optimized 1D diffuser design utilizing quadratic residue number theory and periodic reflection phase gate principles in a highly finished acoustical product.

Achieves a uniform, broadband, one-dimensional diffusion with wide-range scattering of acoustical sound energy.

Scatter and blend the sounds in the room for the listening enjoyment of both music and speech. These diffusers and absorbers help performers hear themselves with others, improves speech intelligibility, increases clarity and tonal separation for music and performances without significantly reducing reverberation times.
