Title: Audio speaker system

Abstract: A sealed speaker enclosure formed from a loud speaker and five square shaped walls. Each wall forming the enclosure is constructed from a thin sheet of acoustically transmitting material and a plurality of perpendicularly intersecting ribs. These intersecting ribs are attached together at their intersections to form a rigid interconnecting rib structure. The rib structure extends across and is attached to one side of the sheet so that the ribs extend transverse to one side of the sheet. The walls are attached together at their edges to form a five sided enclosure. The rib structures of adjacent walls are in contact and attached together to add rigidity to the walls. The loud speaker is attached to the walls to form a sixth side of the enclosure.
