Abstract: A waveguide (1) comprising a shell (11, 12) having an inlet opening (110, 120) intended to receive acoustic energy and an outlet opening (111, 121) for emitting acoustic energy; and a phase plug (13, 14) located into the shell (11, 12) so as to define therebetween a pathway (W) for the acoustic energy from the inlet opening (110, 120) to the outlet opening (111, 121). The acoustic pathway (W) has a longitudinal extension direction (D) between the openings (110, 120, 111, 121) and the directions of all longitudinal splines (S1, S2, S3, S4, S5, S6) of the pathway (W) are perpendicular to the inlet opening (110, 120) at the inlet opening (110, 120) on one ideal longitudinal surface.

Abstract: Audio loudspeaker 100 can be arranged in various vertical arrays, such as 102 or 104. Each loudspeaker 100 includes a generally trapezoidal-shaped housing 120 composed of two forwardly projecting lobe sections 122. A pair of low-frequency cone transducers 130 are housed in the lobe sections 122. A vertically arranged set 132 of high-frequency compression drivers are positioned centrally in the housing to project in the forward direction. Three mid-frequency cone transducers 134 are vertically arranged along opposite sides of the high frequency drivers 132. Each of the low-, mid-, and high-frequency transducers are individually powered and controlled by a separate DSP channel.

Abstract: Audio loudspeaker 300 can be arranged in various vertical arrays, such as 302. Each loudspeaker 300 is identical in construction and includes a housing 310 generally in the shape of a rectangular cuboid. A pair of ultra low-frequency transducers 300 are positioned in the housing 310. Each of the ultra low-frequency transducers is individually powered and controlled by a separate DSP channel, thereby to directionally steer the transducer output.

Abstract: The horn structure (22) is composed of a vertical array of horn pairs (26A-26G) arranged in stacked relationship to each other. The horns (27L and 27R) of each pair have entrance openings (40L and 40R) at the same elevation and disposed side-by-side to each other. The mouths (50L and 50R) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other.

Abstract: The acoustic horn manifold (22) is composed of a vertical array of horn pairs (26A-26G) arranged in stacked relationship to each other. The horns (27L and 27R) of each pair have entrance openings (40L and 40R) on first common plane 44 and at the same elevation and disposed side-by-side to each other. The mouths (50L and 50R) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other. The mouths may be laterally offset somewhat from each other and/or may extend forwardly from respective horn entrances at different distances from each other.
