When building the active filter circuit, high tolerance components must be used to obtain the best performance. Typically they should be 1% or better. A further item to ensure the optimum operation of the circuit is to ensure that the source impedance is less than about 100 ohms. Additionally the load impedance should be greater than about 2 M Ohms.
What Is An Audio High Pass Filter? High Pass Filters Explained
https://soundcertified.com/high-pass-filter-audio/
The basic answer is that an audio high pass filter (HPF) is a type of audio crossover that attenuates and effectively blocks all low frequency signals below a set point.That is, they eliminate low frequency audio while passing high frequency signals to amplifiers, speakers, signal paths, or other audio components.

Active High Pass Filter. A ported subwoofer can lose control of the driver below the tuning frequency. Including a high pass filter in your design can protect the driver from potentially damaging over-excursion. This page presents a design for an active hi-pass filter suitable for use with subwoofers, along with tips on how to determine the optimum design frequency using …

The simple Active high pass filter can be obtained by connecting a non-inverting or inverting operational amplifier to the passive high pass RC circuit. The frequency response of active high pass filter is same as that of passive low pass filter, except that the magnitude of the signal is increased by the gain of operational amplifier.
