Abstract

A panel used for constructing loudspeaker enclosure is disclosed which comprises an outer layer formed by a whole sheet of a first board material, the outer layer facing the outside of the loudspeaker enclosure, and an inner layer formed by two or more closely placed pieces of a second board material flatly attached to the outer layer, the inner layer facing the inside of the loudspeaker enclosure, the area of the inner layer being approximately equal to that of the outer layer, the density of the second board material being less than that of the first board material, wherein the inner layer enhances the overall rigidity of the panel, while provides good acoustic damping to the inside of the loudspeaker enclosure.
