AB  - Traditionally, multi-position room response equalization is performed to improve sound quality at multiple listeners. Furthermore, even after multi-position equalization, due to non-coincident positions of the subwoofer and the satellite, in a multi-channel setup, the combined response of the two loudspeakers may include undesirable spectral deviations in the crossover region, which are different at different positions. These spectral deviations introduced around the crossover, due to the combined phase response, may be fixed by proper choice of the bass management filters. In this paper, we present an objective function that can be used to characterize the performance of multi-position equalization, determine the uniformity of equalization, as well as allow automatic selection of the bass management filters for correcting the spectral deviations in the crossover region.
