Abstract
Loudspeaker drivers used in audio systems are subject to performance variance caused by production deviation of components and assembly processes and consequently audio system performance is influenced by the mechanical attributes of individual loudspeaker drivers of which the audio systems are comprised. This invention provides a solution to minimize the variance of duplicate audio system performance by rectifying the signal processing to minimize loudspeaker variance in duplicated or mass production audio systems.
