POLYLAM dur-SONIC low-frequency absorber

Well suited to absorption in the low-frequency range

The POLYLAM dur-SONIC low-frequency absorber is particularly well suited to absorption in the low-frequency range. It is the perfect complement to the POLYLAM vertical louvre system that is especially effective in the middle and high frequency range.
