Inert Filler is a brand name copyright to Custom Design Design (Newcastle) 1994
Support columns are easily filled with our Inert Filler. The inert material is of a dense consistency, the angular particles, size and shape minimise the presence of voids, minimising resonance which is created in the speaker stand support column and also makes application very simple.
The benefits of mass loading speaker stands will be to enhance the performance of most speakers, especially bass frequencies.
