Abstract
A speaker stand which facilitates the elevation of a speaker cabinet, thereby enhancing the quality of sound distribution for the listening audience. The speaker stand, which is preferably constructed of wood because of its reputation for having excellent acoustical qualities, is comprised of two basic components, an internal structure and an enclosure. The internal structure is comprised of a top lateral surface, a bottom lateral surface and two substantially upright u-shaped cross members assembled in a configuration of a cruciform. The internal structure fits within the enclosure in such a way that the underside of the top lateral surface of the enclosure makes contact only with the top lateral surface of the internal structure. The internal structure slightly elevates the enclosure to prevent it from touching the floor. The speaker stand is constructed to provide freedom of air flow within the chamber as well as allowing the air to freely enter and exit the chamber. It is this combination of structure and material which enables the speaker stand to absorb the vibration.
