I put together a simple 3-way crossover diagram and I have some doubts about it

[Pedroga]

I suggest you do not as your component values do not match what a simple calculator would indicate using 4 ohm drivers with fL = 400 Hz and fH = 3200 Hz (3000 Hz can not be inputted).

I can't find the value of the 112.03uf capacitor, even rounding it to 112uf
I'm looking on websites abroad

 

[Osvaldo de Banfield]

Use 2 x 56 uF or 100 + 12uF paralleled. For normal power levels, 100 or 250V are OK.

As Osvaldo indicates, wiring capacitors in parallel (side by side) gives an overall capacitance that is the sum of the individual capacitances.

That is High School Physics. You will find the following rules for combining components useful as you continue your studies:

And reduces ESR too. Ignore the 30nf down, and in fact, in practice, a 100 or 120uF will do the job. Search por non-polar units.

even rounding it to 112uf

Rounding is perfectly permissible. A calculator gives the theoretical value of a crossover component.

In practice you would select the standard value nearest to the theoretical value (see Netlist's link in post #63).

Sometimes, to achieve an awkward value of C, R or L, you have to combine standard values as indicated in post #64.

Have you tried using Xsim - the links to the software, driver FRD and ZMA files and video tutorial have been provided.

I'm rather 'challenged' when it comes to software but I found Xsim reasonably easy to learn to use. I used Dayton drivers in the link as they give you some files you need to get started.

Without in box measurements, it won't give accurate results, but you can very quickly see the effect of different parts values on frequency response and impedance.

It would help us to help you if you could tell us which drivers you're looking at. Sometimes, that data and a sim won't reveal everything about a driver, such as distortion.
