ABSTRACT:
A loudspeaker enclosure for use in housing loudspeakers, the loudspeaker enclosure comprising a casement having a generally rectangular cuboid shape, the casement including three layers. A first layer and a second layer comprise sheets of metal and are space apart to provide for an inner layer of plastic material. In one embodiment of the invention, the casement is formed by bending a sheet of material including the three aforementioned layers to conform to a generally rectangular cuboid shape. In another embodiment of the invention, the first layer of metal is bent to a rectangular cuboid shape defining four interior surfaces. A flat layer of plastic and a flat layer of metal is applied to each interior surface of the casement. The casement provides a wall having a relatively high density, a high modulus of elasticity and a high damping factor.
