Use of multiple subwoofers in a room is known to help in reducing the variation of response both as a function of frequency and a function of place, but simple geometry-based placement rules guarantee good results only in symmetrical cases. The paper discusses the use of experimental modal anlysis and numerical optimization based on modal behavior to determine the optimal placement of single or multiple subwoofers in rooms with arbitrary geometry and surface properties.
