The hardest thing on earth for a noob to do is replace drivers in an existing cabinet/design. Please, just start a new project!
What you CAN do is try out different parts, and mods and learn about the crossover you have.
The resistor is 5 watts, 2.2 Ohms. The cap is 100V but that doesn't tell you anything about it's Farads, which determines impedance which determines frequency cut off.
What I may also suggest is to check out the LM-1 project I have online. It's fully documented and includes simulation files, allowing you to learn a great deal about speaker design.

Heraldo this is a big area to cover. Many variables. A bit of basic research will be well worth while in the long run..
Btw the cap is 2.2uF. It is on the left hand side.
But agree with you "E" a very awkward question to start with.

Thanks for the answer erik. I'm just trying to learn how to make a proper crossover, so if it does not fit properly I will start a new one. Just want to use the cabinet of the speakers ( Vieta VO-BS30)
Heraldo,
Use the LM-1 as a good guide. Once you understand how and why all the pieces fit together you'll be better able to go on your own. 🙂

You also may be able to make precise mesurement , ears are not enought for such job 🙂
there are many options available .
REW + UMIK-1 , is one of them
good luck , it's an very hard and very interesting job 😉

The value of the capacitor suggests a frequency a little above 10kHz. What about the inductor, may I assume that is connected to the woofer?
Determining a crossover frequency this way doesn't say much directly. A similar effect could be had with a second order filter and a lower frequency, your first order filter plays lower than the numbers suggest. But this all tends to imply that the tweeter is on the smaller side. It also implies inexpensive, but it's better than some.
I would suggest that you find at what frequency a woofer of this size ceases to be useful, and aim for a tweeter that can play comfortably down to that frequency, and maybe consider using a second order filter.
Fairly typical little 4 or 5" plus 1" tweeter, I'd guess, Heraldo. And it is a guess on what little you've told us. 😱
Simplistic crossover. About 3-4kHz. Lots of manufacturers make stuff like this. Always sounds horrible to me.
This is REALLY how you do it:
