Figure 1. A DC blocking capacitor on an audio signal. The output is biased to 2.5 V to feed into a 0 - 5 V ADC. Figure 2. The simulator waveforms. Notice that the output of the circuit is always 2.5 V above the input. The capacitor, if you like, is …
Coupling Capacitor Calculator by V-Cap

We recommend using a -3db point of 1/10th of your desired low frequency response. For the Human beings with audio systems manufactured on Earth, that would be 1/10th of 20 Hz, or 2 Hz. If you enter the number "2" into the -3db frequency field, the capacitor calculator will automatically calculate your optimal value so you will have great sound from 20 Hz and higher. Compare the …

frequency range 0 to 3,000Hz. 5. Also record and plot the RMS current vs frequency. 6. Fixing the frequency at 200Hz, find the RMS current for the full range of capacitances. You should find that current is proportional to capacitance. 7. For a 4.7mF capacitor, keep the frequency at 3,000Hz and switch to a square wave, and
How to Pick Audio Capacitors – Charrette & Beget
https://www.maxpierson.me/2009/03/17/how-to-pick-audio-capacitors/
A typical ESR for a capacitor might be .1Ohm, whereas a low ESR model might be .01ohm.Low ESR seems to be a much touted feature for audio capacitors, especially Black Gates. Since resistance is not dependent on frequency, however, I don’t understand how ESR would have any effect on distortion in the audio signal, and I doubt you’re going to hear a difference …

Effect of various capacitors on frequency response: 1. Effect of coupling capacitors: The reactance of the capacitor is X c = 1/2∏f c . At medium and high frequencies, the factor f makes X c very small, so that all coupling capacitors behave as short circuits. At low frequencies, X c increases. This increase in X c drops the signal voltage across the capacitor and reduces the …

Experimentally, it has been determined that a single frequency element (a capacitor or an inductor) has been determined to roll off at a rate of 20 dB per decade of frequency. And that with two such elements involved the roll off is twice that rate -- …

Re: Size of capacitor vs frequency it blocks If you're planning to build a passive crossover for these, I suggest you use 3000 hz as the target - assuming those spec. sheets are correct. Use 10 ohms for the woofer impedance and 3.5 ohms for the tweeter. Those are the impedances at 3 kHz according to their plots.
