Z-FUR-LG

Fur “Stormy wind”

z-fur-lg-S

Long pile fur to use in addition to the Z-COVER fabric.
In comparison to the short pile fur Z-FUR-SH, the efficiency is improved by 4-5 dB in the critical range 20-200Hz with a slight acoustical degradation of 1-2dB of the lowest and highest frequencies.
The main inconvenient is mostly an increase of the volume.
