Embodiments are disclosed for loudspeaker arrays that maximize a number of transducers and associated channel waveguides for a given length of the arrays. In one example, a loudspeaker array includes a plurality of transducers arranged in adjacent groups on opposing sides of a vertical axis of the loudspeaker array, and a plurality of channel waveguides, each channel waveguide coupled to a different transducer of the plurality of transducers, outlets of each channel waveguide being center aligned with one another along the vertical axis of the loudspeaker array. In the example, at least two inlets of the plurality of channel waveguides are substantially aligned along a horizontal plane, the horizontal plane being perpendicular to the vertical axis.

Horn array

An electrodynamic transducer includes a motor assembly and a diaphragm disposed forward of the motor assembly, the diaphragm having a front surface and a rear surface. A back cover supports the motor assembly and the diaphragm, the back cover creating an air cavity beneath the diaphragm rear surface. The back cover includes at least one heat-conducting member providing a heat transfer path from the motor assembly to the back cover.
