Ok, after reading a lot, everything is almost set.
After reading that piezo needs different treatment, I went on how to crossover my midbass with a piezo, I decided to follow some suggestions from the POINTED OUT ARTICLE.

When I first went for my crossover values in HERE, I was told to go with the following circuit:

And I was also told (before I realized I had a piezo) that I needed to attenuate my tweeter by 22dB because it seems like the woofer would be 96dB SPL while the tweeter 108dB. So someone told me to calculte an L-Pad in HERE and what I got was:

To complicate more, the tweeter box says:
- Always use a 4.7uF/100V polyester capacitor.
Resistor usage table:
Resistor / Sensitivity (2,83 to 1m) / Power Range on 4 Ohms
No Resistor / 108dB / 40W RMS
15 Ohms / 105dB / 60W RMS
18 Ohms / 100dB / 75W RMS
22 Ohms / 97dB / 100W RMS
The label in tweeter box suggests the mentioned capacitor in series with a resistor.
The big question is... alright, I've made an effort... is there any failing thought in the first circuit?
My goal is to level the piezo with the midbass and crossover at 6000Hz/12dB.
