A highpass filter (HPF) works to block unwanted frequencies in the audio signal output (low frequency sounds) below the crossover point from reaching a speaker. Everything above the crossover point will be allowed to pass. Likewise, a low pass filter (LPF) works to block high frequency sounds above the cutoff frequency.

A High Pass Filter is inserted between the preamplifier and power amplifier—it lives in our competitor’s subwoofers–– and it cuts out the bass. First, let me make the argument for why these filters exist because, on paper, it sounds attractive.

Single pole op amp high pass filter. The simplest circuit high pass filter circuit using an operational amplifier can be achieved by placing a capacitor in series with one of the resistors in the amplifier circuit as shown. The capacitor reactance increases as the frequency falls, and as a result this forms a CR low pass filter providing a roll off of 6 dB per octave.
What Is a Highpass Filter? When Should I Use it?

On the simplest level, a highpass filter is just a filter (sometimes called a low-cut) that attenuates low frequencies below a certain cutoff frequency and allows frequencies above to pass. There are many kinds of highpass filters that can appear at various stages in the signal path (e.g., the mic, the preamp, the equalizer/EQ plug-in, etc.) and they can have many different …
