Digitally Steerable Arrays ("DSA") are a relatively new type of loudspeaker system that are not only self-powered, but also employ individual processing for each transducer to control the coverage of the entire array. Using advanced, but well-known techniques of gain-, delay- and frequency-shading, the polar response of an array of transducers can be steered differently than it would behave passively. Steve "Woody" LaCerra discussed DSAs at length in last month's issue.
