ABSTRACT:
An enclosure for a loudspeaker is molded from a rigid acoustically inert material such as a polymer concrete. Preferably, the enclosure has an inner shell of a semi-rigid acoustically absorbent material providing damping for the enclosure. The enclosure may be conveniently manufactured by using a two-piece mold wherein the inner mold piece is sacrificed and forms the inner shell of the enclosure.
