What is Frequency Response？

Frequency response measures how accurately a device reproduces input signals across different frequencies, typically expressed as a graph showing output amplitude versus frequency.

Simply Put:

Imagine a pianist attempting to play a complex piece of music. Frequency response is like their ability to accurately hit every note. A perfect frequency response means the pianist can reproduce every note with the same volume and clarity as the original composition. Just as some pianists may struggle with certain octaves, audio devices can have strengths and weaknesses in reproducing specific frequency ranges, which impacts the overall sound quality and fidelity of the audio output.
