A perforated plate includes a plurality of holes divided into a first set of holes and a second set of holes. Each hole in the second set of holes has an area smaller than that of each hole in the first set; and the holes of the first and second sets are arranged with respect to one another to form a graphic pattern.

A speaker mounting assembly adjustably supports a speaker from a mounting surface. The speaker mounting assembly comprises a speaker enclosure, a support arm, and a mounting bracket mounted to a mounting surface. The speaker enclosure defines a window opening, and the window opening is constructed to receive entry of an insert portion of the support arm. A latch supported by the enclosure and extending from the window opening can be used to engage with the insert portion to automatically retain the support arm when the insert portion is inserted into the window opening. A post extends within the enclosure window and the insert portion engages the post so as to enable pivoting of the speaker enclosure about the support arm. A set screw extends through a channel of the support arm toward the mounting bracket and based on position of the screw, permits pivoting of the support arm about the mounting bracket.
