AV RoomService Equipment Vibration Protectors (EVPs)

About the AV RoomService Equipment Vibration Protectors (EVPs)

The AV RoomService Equipment Vibration Protectors (EVPs) are specialized pads used to isolate equipment from vibrations, enhancing the performance of HiFi systems. They are particularly effective for subwoofers, amplifiers, turntables, and other audio equipment. EVPs are made from a core of high-density molded glass fibers, which act as leaf springs to provide viscous damping. This construction helps in reducing physical motion and widening the frequency bandwidth of attenuation by converting sound energy into heat energy. The EVPs are available in different sizes and densities, including small round and square shapes, with options for rubber or felt tops and bottoms. They are designed to handle loads ranging from 2 to 19 lbs (0.9 to 8.6 kg), depending on the model. Using three EVPs under each subwoofer can significantly reduce vibrations transmitted to the floor and surrounding environment, improving overall sound quality and reducing resonance. EVPs are lab-proven to eliminate vibrations by more than 80% from about 5 Hz and above, depending on the specific model and load conditions.
