Abstract
[Feature] Increasing sophistication is evident in the methods that are used to construct and control the elements of array or cluster loudspeakers, and this is critical to enabling a more “designed” sound field, with control over the coverage of a large arena. Compared with the rather distant past when roadies often just put up a huge pile of loudspeakers and hoped for the best, today’s open-air live sound systems are calculated and designed to a much higher degree. Integral to that design is the idea that one might be able to control where low-frequency sound is directed, in order to avoid polluting the surrounding area too much.
