By using an effective isolation medium and a small and stable physical body that upholds the apparatus, even the negative influence by the airborne vibrations (music) and internal vibrations of the apparatus are reduced. The criteria is to use an isolation medium that is as effective as possible, as close as possible to the apparatus, in order to avoid propagation of frame borne vibrations and resonances into the apparatus. Sold in sets of 4. A complement of four Discs of Silence can support a load of 100 lbs. with the standard tension springs, and 200 lbs. with the heavy-duty springs.
