Abstract: In an audio processing system a center point stereo sound processor in combination with a digital transducer alignment sound processor converts regular left and right stereo audio source signals to sum and difference signals, enabling a center stage spatialized stereo acoustic image to be created directly from a forward-directed loudspeaker unit and a sideways-directed dipole loud speaker unit. The forward-directed loudspeaker unit includes one vertically-mounted loudspeaker. The sideways-directed dipole loudspeaker unit is located directly below and to the sides of the forward-directed loudspeaker unit and includes two speaker cones connected in parallel and wired out of phase with each other. The center point stereo sound processor receives a left and right, stereo, audio signal source and converts the left and right signals into sum and difference signals. The sum, left plus right signal drives the forward-directed loudspeaker unit.

Abstract: Our audio cabinet includes a recess in a cabinet wall in which is seated a control panel comprising a rigid plate bent to form a first planar section and a second planar section connected together by a slanted planar section. An exposed face surface of the slanted planar section includes at least one socket for inserting a plug of a cable. The rigid plate has a configuration that is complementary to the configuration of a perimeter of the recess so the plate fits within the recess with the exposed face surface facing the one side of the enclosure. With the plate seated in the recess the socket faces the one side of the enclosure and the exposed face of the slanted section is offset a predetermined distance from said one side to provide clearance for the plug to be inserted into the socket. The dimensions of the recess and angles of the plate are arranged such that an inserted plug is protected from contact with the floor if the audio cabinet is toppled over.
