Hello friends, I can't find the answer to the question I mentioned in the title. I have capacitors with different different uF values. I have to choose a capacitor to use in my tweeters. Is there a table or site with frequency according to uF value?
@Speedysteve7 Yes, man, I know that, but this is a binary filter. I mean with a coil. I'm just looking for the one with a capacitor.
Google "crossover calculator" and you will find many sites that will do the basic calculation, here is one:

First order tweeter crossovers use just a capacitor.
Second and higher orders use coils in addition to the capacitor.
That said, most tweeter's impedance/resistance value varies with frequency, so best to look at the impedance chart for your tweeters if available, or measure it.

You need the CAPACITORS, 6 dB left hand column.
For example: 3.3 uF gives 12 kHz with a 4 ohm tweeter and 6 kHz with an 8 ohm one.
Then it's just a hi-pass 1st order cap on the tweeter.
That's exactly how I have connected tweeters to their dedicated amp.
Tweeter plays quite low with 1st order.
Others have given you data but it's best to measure the output and adjust.

These calculators assume a resistive 4 or 8 Ohms load, but that is not how it works in reality. Your tweeter has an impedance and as such it does not load as a resistance. You need that impedance plus a frequency response of you tweeter in box, and put those in a basic simulator to see what is happening in reality, otherwise you are basically shooting in the dark.
Maybe I've been lucky.
I've only used JBL2405s (briefly) and 14ohm Raal Lazy ribbons with loads of different passive 1st and 2nd orders. Also used DSP XOs to compare, and that calc prog does near as damn it what it says, when measured.
