ViaBlue High-End TRI Absorbers - Eliminating Vibrations with ViaBlue&trade; Three-Peak-System- 4 Pieces Silver Black - Made In Germany ViaBlue High-End TRI Absorbers - Eliminating Vibrations with ViaBlue Three-Peak-System- 4 Pieces Silver Black - Made In Germany Perfect Sound Control by ViaBlue TRI-System ViaBlue TRI absorbers receive vibrations from vibrating bodies like speakers (such as diaphragms) and devices (such as transformers and reduces them. Through a high pressure concentrated on three minimum points (peaks), maximum pressure is built up as a connection point between vibrating bodies and their base. Through the extreme pressure points, the vibrations are eliminated. This leads to vibration absorption. Diameter: 30mm Height: 15mm  Maximum Load: 200 KG/Set of 4 The functional principle of the TRI Absorber is broken down into three task areas: 1.) reception of vibrations, 2.) concentration of the vibrations received/gathered on three pressure points, 3.) deflection of the absorbed vibrations on the base.
