High-end and hi-fi systems are a combination of high-precision and filigree equipment. Perfectly matched, they are able to reproduce music in outstanding quality. In order for all components to work without interference, they must be kept as free as possible from vibrations and shocks, just like sensitive measuring instruments. Vibrations occur in various ways and can be transmitted by structure-borne or airborne sound. So-called absorbers can help here. The Excellence Gel Absorbers have a special gel mixture in their core which is able to absorb vibration energy. This is how you decouple loudspeakers and devices from their footprint. Now one could say that decoupling the loudspeakers is sufficient. But as described above, there is also the airborne sound which in turn excites the floor space of the equipment. So it makes sense to decouple the devices from their footprints. The same is true for devices like CD-players or hard disks etc. that generate mechanical vibrations themselves which should be kept away from other components.
