Application
An equalizer can be used to correct or "flatten" the frequency response of speakers rather than
designing the speaker itself to be equalized. Some speaker systems don't use separate woofers and
tweeters to cover the bass and treble frequencies but rather include full-range drivers. However, this
speaker system is sold with an active equalizer designed to correct the poor frequency balance of
those drivers. That equalizer must go into the sound system before the amplifier so that the
amplified signal is sent to the speakers. The signal has its response increased at the frequencies
where the response of these drivers falls off, producing a high fidelity reproduction regardless. Ateis
audio processors give you the same solution without using an external equalizer, it's all done in the
software component PEQ.
