Abstract
A method for adjusting frequency response curve of a speaker comprises these steps: testing sensitivity of the speaker in at least two types of hardware conditions and recording corresponding frequency response curves; selecting a frequency response curve that comes closest to falling within a predetermined range for selected frequency ranges; and adjusting the selected frequency response curve with a filter.
