Hi guys,
I got a high quality 23uf cap but not the 22 uf that the schematic asks for. Would this pose a problem or only be of minor concern?

Hi!
According to a quick comparison, there is no difference that can be observed.
See the simulations with 22uF, 23uF and both together.
I used a 6ohm dome tweeter data I have for this example.
With 22uF
With 23uF
Both superposed
And just to see a more drastic change, see with 22uF and 10uF responses superposed simulations. Even that, not much difference.

Usually good film capacitors have a tolerance of ±5 %. Occasionally you'll see ±1 % types, but usually not 22 uF. For electrolytic capacitors, good ones have ±20 % tolerance. So 22 vs 23 uF is not likely to make any difference. The unit-to-unit variation of the driver is likely to swamp the difference in capacitance.
