I have these dampers for elderly sentence Sony boxes purchased, were previously on thick foam. As is well known, nothing lasts longer than a provisional arrangement, I have now taken care of with the dampers for Remedy. The installation is very simple: box roll over, make tidy with Sidolin clean, and then the self-adhesive paperboard Oehlbächer in the corners. The whole thing is done in 5 minutes.
What stands out is the material of the damper: Solid, heavy rubber, which is not too soft and not too hard. As a ramekins from NEM car tires gouged, quasi. If you compare the box again, one notices on a hard surface directly to the damping effect. Acoustically ... yes mei, I have no instrument at home, but what I can say is that the vibrations are definitely kept clean off the ground and no more deep bass to strike a roar. Thus there is theoretically a perfect score, but I have to deduct a star for the price, which is just a tick too high for so little rocketry.
