Abstract
A substantially full-range loudspeaker system for acoustic sound reinforcement can include a woofer section with a first loudspeaker driver configured to reproduce audio signals in a first frequency range and a controlled-directivity horn section configured to reproduce other audio signals in a different second frequency range. In an example, the horn section includes a second loudspeaker driver comprising a cone-diaphragm transducer and a dust dome, an acoustic lens having a first side and an opposite second side, wherein the first side of the lens is coupled to a sound-projecting face of the second loudspeaker driver, and a waveguide coupled to the second side of the lens, wherein the waveguide comprises walls that follow arcuate paths in horizontal and vertical planes.
