The Design of Three Unusual Loudspeakers for the High Court of Australia

Document Thumbnail

Three unusual loudspeaker systems providing specific radiation patterns were designed as part of the overall design of a sound reinforcement system for the High Court of Australia. The first loudspeaker was a distributed array of dipole loudspeakers, each housed in a trough; the second was an acoustically curved line array utilizing 34 drivers; and the third was a short tapered line array utilizing six drivers and a tweeter. Primary requirements for each loudspeaker were its architectural shape and finish, radiation pattern, and frequency response. The integration of these requirements necessitated a holistic approach to the design of each loudspeaker. The design process, the hardware implementation, and the performance of each loudspeaker are discussed.
