Turntables > Turntable Enhancement & Upgrade Kits > SRM Platter Damping Ring 19mm

This is SRM’s superb Platter Damping Ring (PDR), designed to fit tightly around the rim of the platter, effectively forming a peripheral wave trap to absorb vibration / resonances / platter 'ring' and enhance rotational stability.
This ring is 19m deep, so it fits most turntables with metal or alloy platters perfectly, but it will fit any turntable with a standard diameter platter, providing it is at least 19mm deep. (If you are using a deck with a shallower metal or glass platter, you should go for the 10mm deep model).
Over 1000 PDRs have been sold, working sonic magic on turntables as varied as Thorens, Roksan, Linn, Project, Ariston and Garrard.
The PDR is made from a particular type and grade of rubber-like synthetic polymer, specifically selected for its damping properties at the frequencies which cause problems within LP replay systems.
