  • Patent number: 5758852
    Abstract: A loudspeaker suspension system for suspending a plurality of individual loudspeakers from an overhead support in spaced apart relationship for adjustment to different related positions and orientations relative to one another to selectively focus the acoustic throw of the loudspeakers. The system includes a plurality of frame members mounted to the respective loudspeakers and a plurality of connectors for connection between respective adjacent pairs of frame members. The connectors include a pair of elongated oppositely disposed connecting arms for connection from their respective distal ends with the respective loudspeakers and further include a pivot joint connecting the medial ends of the connector arms together so that the respective connecting arms may be pivoted to angle the respective adjacent pair of loudspeakers relative to one another.

  • Patent number: 5749137
    Abstract: A method for suspending a plurality of individual loudspeakers from an overhead support in spaced apart relationship for adjustment to different related positions and orientations relative to one another to selectively focus the acoustic throw of the loudspeakers. The method includes selecting frame members having respective first coupling elements and connectors including respective second coupling elements and respective pivot joints. The frame members are mounted to the loudspeakers and the respective second coupling elements are coupled to the respective first coupling elements between adjacent pairs of frame members to position the loudspeakers adjacent one another. The pivot joints are then adjusted to pivot the loudspeakers to selected orientations and the resulting apparatus is then suspended from an overhead support.
