Ceiling loudspeaker with corrosion-resistant matte white painted grille, suitable for installation in ceilings made of any material. Quick assembly via a circular ceiling cutout, in which the speaker with transformer and mounting ring are mounted using snap-in technology. The connection to the 100 V mains, as well as any potentially necessary volume adjustments, is carried out via an easy to handle pressure spring terminal. The shapely grille is fastened quickly and practically with a bayonet connection.
