The invention relates to a loudspeaker box designed as a shell construction, where the outer and inner peripheral surfaces of the box are made of reinforced plastic and are preferably twin-curved with a continuously varying radius of curvature, where the distance between the outer and the inner shell is not constant and where the space between the shells is filled with a light material with good adhesion to the shells, preferably foam plastic. This design principle is intended to avoid natural resonances while at the same time ensuring low weight and high strength.

A loudspeaker box comprising an inner plastic shell and an outer plastic shell, said shells being twin-curved, said shells being maintained in a spaced relationship wherein the radius of curvature of said shells is continuously varied so that the distance between the outer and inner shells is not constant, and being linked by a plastic foam material which adheres to the inner and outer shells and fills the space between them.
