Abstract (en)

The present invention relates to a method and a system for reproducing audio frequencies in a sound reproduction system, comprising at least one loudspeaker (5) mounted in a loudspeaker cabinet and in which the frequency response (1) of the loudspeaker is equalized with a filter (4). Prior to feeding a signal into a wideband one-way loudspeaker (5) reproducing frequencies substantially over the entire audio range, the output of said loudspeaker being an audio signal, the frequency response (1) of the loudspeaker mounted to its cabinet is equalized with a filter (4), which is a wideband filter (4) also covering substantially the entire audio range. With the filter an approximate inverse response (2) is implemented in the desired passband of the loudspeaker system comprising said loudspeaker mounted to its cabinet, the inverse response being formed according to a frequency response of said loudspeaker system, which frequency response is a measured frequency response of said loudspeaker system. If desired, the measured frequency response can be averaged in the frequency domain and the inverse response is then formed from this averaged frequency response. <IMAGE>
