Abstract: A base for a loudspeaker enclosure is formed of a lower base disk, an upper support disk and an interposed spacer element which together define an internal hollow space to which structure-borne sound is transmitted. The area of contact between the spacer element and the disks is relatively small is comparison to the area of the disks which defines the hollow space at top and bottom sides thereof. In a preferred embodiment, the disks are formed of a sound-insulating material, preferably rubber, and the spacer element is a spacer ring that peripherally defines the hollow space. Also, a bracing foot, preferably of an inverted frustoconical shape, may be carried upon the upper support disk, for which purpose a support plate is centrally mounted thereon.
