Publication number: 20120080260Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, a method is provided which comprises forming a loudspeaker frame so as to define a driver housing portion, a horn portion, and a conformal portion. A driver aperture is defined for the driver housing portion, and a port aperture is defined for the horn portion. A driver is attached to the loudspeaker frame proximate to the driver aperture. A rear baffle is applied to a first conformal portion surface of the conformal portion of the loudspeaker frame. The rear baffle defines a horn cavity wall of a horn cavity of the horn portion. The horn cavity has an increasing cross sectional area as the distance from the driver housing portion increases. A grille is applied to a second conformal portion surface of the conformal portion of the loudspeaker frame.Type: ApplicationFiled: December 8, 2011Publication date: April 5, 2012Applicant: RGB SYSTEMS, INC.Inventors: WILLIAM CAMERON STEWART, JR., ANDREW C.

Patent number: 7455271Abstract: A speaker mount includes a support structure attachment, an adjustable mount connected to the structure attachment and including a first connector, and a speaker attachment including a second connector. The first and second connectors may selectively be connected or disconnected, permitting a speaker to be connected to and disconnected from the remainder of the mount. The first connector is mounted to a ball. A lock plate is mounted at an opposing side of the ball from the first connector. A fastener controls the distance between the first connector and the lock plate. In one position, the fastener draws the lock plate and first connector towards one another, fixing the lock plate in a position on the ball, and in another position allows the first connector to be moved relative to the ball. The mount permits orientation of a speaker in a variety of positions relative to a support structure.Type: GrantFiled: August 17, 2005Date of Patent: November 25, 2008Assignee: RGB Systems, Inc.Inventors: David Pincek, Andrew C.
