Abstract
An acoustic hailing device includes an outer housing and a pair of compression drivers oriented in the outer housing adjacent one another. Each of the compression drivers includes two diaphragms oriented facewise relative to one another within each compression driver. One or more waveguide housings are coupled to the outer housing, the one or more waveguide housings forming a portion of a waveguide associated with each of the compression drivers. A pair of driver covers are each coupleable to one of the compression drivers, each of the driver covers forming another portion of the waveguide associated with each of the compression drivers.
