Finite element analysis is a powerful and widespread mathematical technique capable of modeling even very complex physical systems. The use of this method is quite common in loudspeaker design processes, although simulations may often become time consuming. In order to reduce the number of simulations needed to define an optimal design, some advanced metaheuristic algorithms can be employed. The use of these techniques is well known in many optimization tasks when an analytical description of the system is not available a priori. In this paper a comparison among three different optimization procedures in the design of a compression driver is presented. The algorithms will be evaluated in terms of both convergence time and residual error.
