Hello,
I wish to built 2-way active crossover with 1300 Hz cutoff frequency.
I have theorical schematics, please see Figure 5 and 6 in link bellow:
AM Active Crossovers
But I don't know how to calculate all components nominals.
Maybe someone know equations or maybe can calculate these values?
Best regards,
Tadas

If you are happy with different topology then here you can find a decent paper and solution from TI.
https://www.ti.com/tool/TIPD134
Paper also shows how you can use TI filter design tool to change xover frequency.
In the lower section of the page they also included a TINA sym model if you want to check the changed circuit.

I hope that you will find these article from the former Linkwitz Lab helpful.
I will also strongly encourage you to consider a ready built box from Weilliang Audio. You can specify the crossover frequency when you order. This one is head and shoulder above other Chinese offers. I replaced the 5532 IC with LME49720 genuine product. The result is excellent.

Thanks guys, but I want to try gyrators based schematic. I only need equations to calculate preferred values.
How steep do you need the XO? If 1st order you might get away with a PLLXO, which is both cheap and adds no "electronic haze” (but at the expense of versatility). What drivers are you using?
And do note that a basic active XO does not usually deal with specific driver issues that a passive often solves.
