A method and system for maximizing radiated power from a linear array of acoustic projectors. In one case, the method realizes omni-directional acoustic beam patterns from a linear array of acoustic projectors contained within an acoustically-impervious enclosure with an acoustically transparent aperture. In another case, the method realizes an efficient set of beams for a conventional horizontal projector array or a similar acoustic projector array, which may be within an acoustically transparent enclosure. Drive signals are determined by finding a mutual impedance matrix that characterizes the interdependence of the acoustic projectors and solving an eigenvalue problem for the mutual impedance matrix. One of the eigenvalues is selected on the basis that it maximizes radiated power, and the corresponding eigenvectors are used to derive the corresponding drive signals.
