ABSTRACT:
A lay-in tile type system is disclosed for supporting speakers in a new or existing suspended ceiling includes a perforated base section providing maximum free air space. A perforated surface also helps the lay-in tile system blend in with the overall suspended ceiling in which the system is installed. The system further provides integral flanges that form a T-shaped member to support at least a portion of an adjacent ceiling tile, obviating the need to purchase, cut and install a replacement grid member. The base and the flanges are constructed from a single sheet of material that is folded to form the flanges. The base is sized to fit within a portion of a conventional ceiling tile grid opening, and has substantially ninety degree comers so that the ceiling grid opening is completed by a ceiling tile sized with a simple straight cut, simplifying installation.
