Primacoustic Impaler Offset Mount for Broadway Panels

Primacoustic Offset impalers offer an effective method to increase bass absorption by introducing an air space behind the panel. This unique impaler features a U-shaped design with pivoting darts for left-hand or right-hand installations. The deep 3½? stand-off matches that of a typical 2?x4? making it easy to use in conjunction with standard building supplies. By adding the cavity an additional octave of bass attenuation can be achieved!Comes in a pack of 8.
