How did you measure your response? As it is, it looks pretty good. You might try a 4 ohm instead of the 5.6 if you'd like to lift that treble response a bit. But that is that an impedance graph in the lower left? If so, you'll melt down amps with it.
Thanks for your answer !For the response, i downloaded the FRD and ZMA files from parts-express and loaded them into VituixCad2. Then noodled around with the crossover until this result !And yes, it is an impedance graph in the lower left. What do you mean i will melt amps with it ? What i read about it is that it is the lowest figure that can be a problem, which is 3.3ohm. So i was thinking on buying the Wondom 2x400W 3Ohm amp, wich is super cheap btw. Would this be OK ?
He's looking at your rear port graph, not impedance. Your impedance looks fine. However, I think you are going to need to increase the woofer inductor. .56mh seems very low and your crossover shows a peak at 1.4k for the RS180. You will want to flatten that out, probably by increasing the inductor value. Typical 4ohm woofer would be more like 1-1.5mh.No. You should not need to invert woofer polarity.
Polarity reset to normal. This is as close as i can get to flat with this crossover. But isn't it the gray line that represent the average frequency response between woofer and tweeter ? That red bump in the initial graph is going to be heard ? Because at 1400Hz with polarity inverted, that gray line is lower than the red one.
Okay, I bet your are doing this based on Kirby Does Audio tutorial on YouTube. *sigh*It's a bad tutorial. I am guessing you did not account for baffle step loss, nor did you account for real impedance inside a box. Correct?
Correct ! I have no idea what you are talking about, I am all ears...
1. Know what the enclosure dimensions are: LxWxH...

Go to Parts Express Tech Talk forum for help. Good group and lots of newbies.
I think i will dig a little more into all this and order the parts + microphone. Making different sized enclosure and baffle is no problem for me since i am a cabinet maker and i have my own workshop !From the measurements i will get, i Will order some more parts for the crossover. Thanks for the help !
Great! Making the cabinets is half the battle. Keep us posted on your developments.
