Claim One:
1. A method for equalization of a loudspeaker, the method comprising: determining a noise score for a candidate gain reduction parameter level in a plurality of candidate gain reduction parameter levels, wherein the noise score is based on the relative reduction in a signal-to-noise ratio caused by the candidate gain reduction parameter level; determining an equalization effectiveness score for the candidate gain reduction parameter level, wherein the equalization effectiveness score is based on a number of octaves in a measured frequency response where an equalization effect is achieved using the candidate gain reduction parameter level; determining an equalization non-effectiveness score for the candidate gain reduction parameter level, wherein the equalization non-effectiveness score is based on an area between a target frequency response and the measured frequency response where the target frequency response is not reached using the candidate gain reduction parameter level; determining a composite quality score for the candidate gain level reduction using the noise score, the equalization effectiveness score, and the equalization non-effectiveness score; and designing a compensating filter for the loudspeaker using the candidate gain reduction parameter level if the composite quality score is better than composite quality scores of all other candidate gain reduction parameter levels in the plurality of candidate gain reduction parameter levels.
