Abstract: A high frequency waveguide and methods relating to the design and use of the waveguide are described. The waveguide can include an acoustic input to receive an audio input signal from a high frequency driver, an acoustic output to broadcast sound, and a plurality of acoustic paths extending from the input to the output. A first path of acoustic paths is divided into two paths when a width of the first path is greater than ½ wavelength of a highest frequency at the input. In an example, each of the plurality of acoustic paths carries across all frequencies from the high frequency driver. In an example, the paths each have a first port receiving audio and a second port outputting audio, and the paths enlarge from the first port to the second port.

Abstract: A speaker assembly rigging system is provided with a first frame and a second frame that is adapted to couple to the first frame. The system includes a cam and a link. The cam is pivotally connected to the first frame about a pivot point. The cam includes at least two cam surfaces, and each of the at least two cam surfaces are offset at a different radial distance from the pivot point corresponding to a splay angle. The link has a proximal end that is pivotally connected to the second frame and a distal end having a contact surface. The link extends from the second frame in a deployed position such that the contact surface engages one of the cam surfaces.

Abstract: A speaker rigging system is provided with a frame, a cam pivotally connected to the frame about a pivot axis and a sector secured to the cam with a peripheral surface with a plurality of teeth formed therein. The speaker rigging system also includes a lever arm and a pawl. The lever arm is pivotally connected to the frame with a proximal end and an intermediate portion extending between the proximal end and the pivotal connection to be oriented proximate to the sector. The pawl extends from the intermediate portion of the lever arm and is spring-biased toward the sector for engaging one of the plurality of teeth to lock the cam to the frame in a locked condition.

Abstract: A cart assembly is provided for transporting multiple loudspeakers that are stacked in a pre-assembled line array. The cart assembly includes a base and at least two wheels that are mounted to the base. A plurality of loudspeakers having a non-parallelogram cabinet are stacked on the base in a vertical line array with a splay angle between a pair of axis each extending through about a horizontal axis between adjacent loudspeakers. The cart assembly is coupled to at least one of the plurality of loudspeakers. The cart assembly and the plurality of loudspeakers arranged in the vertical line array are transported to a desired location.
