Broadband Treatment

Brandt Audio Devices broadband treatment is designed for broadband sound absorption from the highest audible frequency down to the specific frequency for the selected unit.

Brandt Audio Devices broadband treatment is designed for broadband sound absorption from the highest audible frequency down to the specific frequency for the selected unit. The absorption coefficient of the high-density fiber is poor in the low-frequency region. We use ONLY lightweight, low gas-flow-resistivity fiber. We have found that fiberglass outperforms Rockwool for most applications.
