Notch Filter - Hack Audio
https://www.hackaudio.com/digital-signal-processing/basic-filter-effects/notch-filter/
A notch filter decreases the amplitude of frequencies in the mid-range of the spectrum. It allows the low frequencies and the high frequencies to pass through. Audio engineers use this type of filter to cut out a problematic frequency. A notch filter can be implemented by modifying the low-pass filter effect. Instead of using one sample of delay on …

Active notch filters were actively used during the earlier decades for amplifier and audio applications for eliminating of 50- and 60-Hz hum interferences. These networks have been although somewhat awkward from the standpoints of center notch frequency (f0) tuning, balance, and consistency.
Notch Filter - Audacity Manual
https://manual.audacityteam.org/man/notch_filter.html
Notch Filter sharply attenuates frequency-specific noise like mains hum or electrical whistle with minimal damage to the remaining audio, by cutting a "notch" out of the frequency spectrum at that point. Accessed by: Effect > Notch Filter... Frequency Enter any frequency up to half the sample rate into the frequency text box (default is 60 Hz).

Notch filter experiment. For those who don’t know what notch filter is I’ll explain in short: the task of a notch filter is to reduce the strength of the audio signal in certain frequency range. Such a filter is usually used in a single driver (also known as broadband or full-range) speaker designs. Because it has only one driver it is often very hard or impossible for such a …
Notch Filter Circuit || 5+ Important Circuits and Analysis

Audio notch filter is a very important filter for audio engineering. Notch filters removes the spike and noises to make the audio better. The circuit diagram of a basic audio notch filter is given below. As we can see, the circuit can be designed using passive elements like – resistors and capacitors. The generalised values of them are also given.

Most drivers has a large impedance peak at it's resonance. For crossovers to works as expected, it's important to have a nearly resistive impedance, at least in the crossover frequency region.
