Damper isolation feet can be used under any audio component in order to filter structual vibrations as well also acting as noise filter suppressors for vibrations generated by the component itself. They are sold in sets of 3 or 4 pcs.
The top and bottom cups are machined from a solid aluminium plate.
The cups are separated with multi layered silicone& aluminum dampers which filters vibrations up to 3000 Hz. Dampers are simply positioned under any audio component either under metal plate, spike or under rubber feet.
If audio component has off centre of gravity, reposition dampers acordingly. There is no leveling adjustment in dampers. Lower cup has rubber ring inserted to minimise sliping- but it can be removed. For higher load just add more dampers.
