AB  - Over the last two decades loudspeaker arrays have been employed increasingly for sound reinforcement. Their high output power and focusing ability facilitate extensive control capabilities as well as extraordinary performance. Based on acoustic simulation, numerical optimization of the array configuration, particularly of FIR filters, adds a new level of flexibility. Radiation characteristics can be established that are not available for conventionally tuned sound systems. It is shown that substantial improvements in sound field uniformity and output SPL can be achieved. Different real-world case studies are presented based on systematic measurements and simulations. Important practical implementation aspects are discussed such as the spatial resolution of driven sources, the number of FIR coefficients, and the quality of loudspeaker data.
