Abstract
An apparatus for mounting a flat panel sound radiator into a tegular ceiling. The tegular ceiling has openings defined by main beams and crossbeams. The main beams are secured through hanger wires to a hard ceiling. The main beams and the crossbeams have flanges with the crossbeams resting on the flanges of the main beams. The mounting apparatus has a tegular frame with reveal edges formed by multiple horizontal and vertical plates. A flat panel radiator is mounted inside a tegular frame with the lower edge of the tegular frame below the flanges of the main beams. The radiator panel can be fabricated from a honeycomb core. A combination of containment elements and isolation elements are used to isolate the radiator panel from the tegular frame both mechanically and acoustically. An acoustic scrim is attached to the bottom of the tegular frame.
