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.
