AB  - Vertically arrayed Loudspeaker Systems have become widely used in several fields of applications: concert sound, large scale systems, corporate events and so on. In this kind of systems the design of a proper Acoustic Waveguide is a key point for the system's performances. An Acoustic Waveguide, properly designed for this purpose, should be optimized for several features at the same time: acoustic loading properties, proper driver-throat matching, minimum internal reflection, low distortion and, most of all, proper wave front curvature optimization for good array-ability. An example of a practical approach to the design, dimensioning and optimization of acoustic waveguide will be shown through loudspeaker system designing principles together with computer simulations and measured final results.
