Abstract
An acoustic assembly may include acoustic emitting devices attached to an enclosure. The acoustic assembly may further include an acoustic horn for influencing sound emitted by one or more of the acoustic emitting devices. For example, the acoustic horn may influence a beamwidth of sound emitted by one of the acoustic emitting devices. As a further example, the acoustic horn may influence a first beamwidth of a first acoustic emitting device and a second beamwidth of a second acoustic emitting device in a crossover region between the first acoustic emitting device and the second acoustic emitting device. The acoustic horn may include a waveguide attached to at least one integrator. The at least one integrator may include at least one plug and at least one lens.
