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 results from the two calculators:
Increasing Coupling Capacitor Values in Tube …

Actually, by thoughtlessly increasing coupling capacitors values you have more chances to degrade the amplifier performances than improve it, and end up with L.F (in)stability issues. A good read about this topic is the small booklet titled: "Feedback" (Audio Handbook No.2) by N.H Crowhurst (especially chapters 2 and 3) It's old (1952) but ...

When selecting a capacitor for coupling/DC blocking applications, the key parameters to consider include impedance, equivalent series resistance, and series resonant frequency. The capacitance value primarily depends on the frequency range of the application and the load/source impedance.
Coupling & Bypass Capacitors

The value is usually not especially critical, and there are a few general guidelines that can be applied in the vast majority of cases. There is only one formula that's really needed - at least for coupling capacitors ... C = 1 / ( 2π × f × R ) or ... f = 1 / ( 2π × C × R )

Now that we know what a coupling capacitor is and how to place in a circuit for coupling, the next thing is how to choose an appropriate value for the coupling capacitor. The value of the coupling capacitor depends on the frequency of the AC signal being passed through. Capacitors are reactive devices, meaning they offer different impedance (or resistance) to signals of different …

Values I have seen go from 2nF (old radio which didn't do bass!) to 0.68uF. If you want to buy some for playing with then 10nF, 22, 47, 100, 220nF would be a good place to start because you would be within 50% of most reasonable values. 6.8uF would not necessarily be 'transparent'. It would be big, and might increase hum pickup or RF interference.

The coupling capacitor CG blocks the high DC voltage at the plate of the driving tube while allowing audio signals to pass. Unless bass attenuation is desired, the capacitor needs to be large enough to induce very little signal attenuation at bass frequencies. (82Hz is the lowest note on a guitar with standard tuning.) It shouldn't be too large, however, or unwanted effects like …

The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to .001 uF. Above that value, polypropylene is the type of choice, with nearly the same qualities of dissipation factor (DF) and dielectric absorption (DA) as polystyrene (these are the two capacitor “qualities” that most …
