Cannot withstand 10kg/absorber as promised
The described max load of 10kg per pad is nowhere near these absorbers can handle (40kg total). Under a combined weight of just 18kg which is 4,5kg per pad the absorbers lose practically all of the absorbing capability as they bottom out. They work fine with a load of about 2,5-3kg/pad, no more. So do not try to use these under an equipment weighting more than about 12kg total. I bought these to be fitted under my BKE XLS200 mk2 subwoofer which weights about 18 kilograms and they were useless - all of the vibrations were conducted directly to the floor and I had to replace them with my old Norstone absorbers.

Afterwards I installed Dynavox SDS4 absorbers to my gaming set, under a small Audio Pro Subsoniq subwoofer weighting 10kg at which they work adequately and as promised absorbing the vibrations efficiently.

Tres bon amortisseur
Tres bon amortisseur mais pour des appareils assez legers.
Je les ai installes sous un DAC SMSL
