Abstract: A ceiling speaker assembly is disclosed. In one or more embodiments, the ceiling speaker assembly includes a three-dimensional support frame attached to a perforated grille. The support frame is configured with a speaker aperture adjacent to which a speaker is mounted and a port aperture. The speaker aperture and port aperture are configured such that the speaker aperture is in communication with the front of the speaker and the port aperture is in communication with the rear of the speaker. In one or more embodiments, the support frame includes a horn cavity that functions as an acoustical cross-over such that higher frequencies generated by the speaker are emitted primarily through the speaker aperture and the lower frequencies generated by the speaker are emitted primarily through the port aperture.
