PA systems looking to cover a wide audience area with coherent sound are limited by current horn technology. With conventional single-surface horns, one can achieve either high input impedance or wide directivity but not both. Existing wave-shaping devices try to overcome these issues, but most are unable to transmit a wave coherently (without reflection, diffraction or resonance).
In this paper, we present a new type of wave-shaping waveguide based on maintaining single-parameter wave behaviour throughout the waveguide over a wide frequency range. Various examples are included illustrating the performance benefits of this type of waveguide compared to conventional solutions.
