Zusammenfassung:	A method of installing a ceiling speaker system includes inserting a top end portion of an enclosure of a speaker system into a hole in a ceiling such that a spring-loaded tab of the speaker system is caused to pivot about a pivot axis as the spring-loaded tab comes into contact with an edge of the hole. The top end portion of the enclosure is moved upward, through the hole until the spring-loaded tab is clear of the hole. A lead screw of the speaker system is rotated about its longitudinal axis to cause the spring-loaded tab to be displaced toward a flange arranged along a bottom end portion of the speaker system, and thereby clamping the ceiling between the flange and the spring-loaded tab. The longitudinal axis of the lead screw is coincident with the pivot axis of the spring-loaded tab.
