ABSTRACT:
A loudspeaker cabinet has an annular frame mounted on its front face to support a multiplicity of louvers that are coupled together by a transversely extending coupling arm. The louvers can be opened when the loudspeaker is operating. When the loudspeaker is not in operation the louvers can be closed to protect the speaker against dust accumulations. The louver coupling arm is located in cut outs formed in the louver rear edges so that the arm is relatively inconspicuous.
