A loudspeaker for projecting sound over a listening area having a driver and a horn in which the horn has a coupling portion communicating at an interface with an outwardly flaring portion, the horn forming an elongated slot at the interface and being provided with means for controlling the sound energy along the axis of elongation of the slot, namely a slot which is narrower at one end and flares outwardly to the other end, or a plurality of transverse veins dividing the slot and sound channel.

Loudspeaker and horn therefor

A high-frequency constant-directivity horn including a relatively large throat driver and a relatively large throat for receiving sound from the driver, further includes a pair of vanes mounted wholly within the throat, respectively above and below the longitudinal axis in a vertical plane, for effectively dividing the throat into three smaller 'pseudo horns' for directing and shaping sound waves from the transducer up to the point of termination of the vanes, beyond which the individual wavefronts mix within and fill a slot in a middle section of the horn, forming a coherent wavefront for passage into a front section of the horn and transmission therefrom, substantially free from wave interference and beaming effects.

Constant directivity loudspeaker horn

A multiple driver manifold for coupling four high frequency drivers to a single horn. Two drivers are mounted in a 'Y' or 'skewed' configuration, and two additional drivers are mounted so as to be directly opposed to one another along a line perpendicular to both the horn throat on-axis direction and the general plane of the 'Y' configuration. Sound radiated transverse to the horn on-axis direction by the opposed drivers is 'ray-reflected' by a unique ray-reflection summation plug located at the internal hub of the four acoustic paths.
