AB  - Loudspeaker panels represent a class of loudspeakers, whose electrical, mechanical, and acoustical properties differ completely from conventional loudspeakers. However, the acoustic properties are mostly associated with lower performance. The position of the excitation is one of the crucial parameters to optimize multiple parameters such as the frequency response in terms of linearity and sensitivity. This paper describes an approach to find the best excitation position for an exemplary distributed mode loudspeaker (DML) by considering efficiency and the averaged sound pressure equalization. An evaluation of the measured response in the horizontal plane of 25 excitation positions is presented and an optimization algorithm is used to filter every position to a certain acoustical quality standard.
