ABSTRACT OF THE DISCLOSURE A grille for protecting a loudspeaker or the like comprises two substantially identical parts, each part being formed with bars defining a plurality of openings. When the two parts are placed together in back-to-back and head-to-toe relation, the openings in one part are out of register with the openings in the other part. This provides a plurality of circuitous paths through the grille for the passage of sound or the like, but there are no straight-line paths through the grille for the passage of vandalizing imple- ments or the like.
