In a helpful spirit, I looked through this whole thread from the beginning.
OP wants to use a 1 1/8th Dayton tweeter + Dayton 4.5" midwoofer (as bass) + Wavecor 4.5" midwoofer (as midrange) in a 3-way.
Not sure this makes sense but anyway.
If we're dubious of the FRD and ZMA files supplied so far, we know Dayton provides FRD + ZMAs on the PE website, and so does Wavecor on their own site. I downloaded them all and eyeballed them against the graphs in the datasheets - they are correct.

I tried to make something workable here using them. Don't know how to apply bafflestep and diffraction curves.
Got to say -- the tweeter padding is ridiculous - a consequence of using the tiny, insensitive 4.5" woofer.
Overall, I think one's money and time is better spent on a published design 2 way with 5" or 6" woofer.
The design goal of a 3 way with 4.5" bass + 4.5" mid + >1" tweeter doesn't make much sense to me.

Thanks. No hard feelings from my side either. I think we just have different ways of communicating and opinions about how to approach an inexperienced builder. They seemed to be clashing here. Sorry.
I use a very old FRD consortium tools - Baffle Diffraction simulator and Frequency REsponse combiner
The BDS tool allows you to put in a quadrilateral baffle with optional chamfers or roundovers and arbitrary driver placement for up to 5 drivers. It then simulates on-axis ripple due to diffraction and baffle step.
The FRC tool allows you to take an IEC baffle and subtract that from the manufacturer curves, then add in your own baffle signature. you can also subtract an infinite baffle bass response (often used) and then add in (which subtracts) your bass response. FRC then derives minimum phase and exports in FRD format.
You can then use them in your xo modeling tool of choice (don't forget X,Y,Z offsets)
In the vein of the last few posts, I'm going to suggest that the OP take a short step away from the xo work for now and let us help him get his driver files together so they're as close to accurate as the process allows without in situ measurements before plugging them back into XSim.
But the first thing we need to know before we can help out is your basic design criteria. Like:
How small does it need to be or how big can it go?
bookshelf/ floorstander/ desktop/ near wall/ away from the wall? (So will it need baffle step compensation or not?)
4ohm or 8ohm nominal?
How low do you want it to go? Is there going to be a sub? So 80Hz/ 60Hz/ 40Hz?
How loud do you think you want it to go?
And anything else you might be particular about.
Because the 1st thing I'd suggest in your design is doubling up your woofer. But that's only if you'll need baffle step compensation, if you're ok with 4ohm nominal, if a bigger box is ok, if you want it to play somewhat loud and if you are happy with a low end down to only about 60Hz. Personally, if I wanted to keep the speaker thin but was ok with a floorstander that has some depth, I'd consider a different 4" or 5" woofer, like the Dayton ND105-8 or ND140-8 for eg, both of which will get you down in the 40Hz area but will need a bigger box for 2 of them.
If you are ok with a wider floorstanding speaker, I might consider going up to a 6" woofer or 2, perhaps something of high value like the SB16PFC. Maybe even with a mid from the same line too. A 3-way as a first project is very ambitious and for that reason, I might want to stick with more inexpensive but high value drivers like that SB line. Depends on your own budget of course.
If you can answer those questions for us, I think we may be better equipped to help you out.

hello everyone i started on xsim a few days ago i want to make a 3 way crossover but because i have professional components, the frd and zma files weren't available i have the sica 10fe 3 cp 8Ω woofer the sica 8m 1,5cs mid and the visaton sc 10 n tweeter i'll send the pdfs too.Now i got the curves from graph tracer and edited them, with paint 3d i erased everything except the frequency and impedance charts everything works in xsim, i noticed tho that the curves of the drivers, are not aligned with the x and y axes of xsim based on the factory pdf. Is it possible to adjust the axes of xsim so that the curves appear as they do in the factory pdf?? and if so how? As you guys can see for yourself in the crossover photo i sent the frequency of each driver if you compare them to the factory pdfs does not align they start at more hz and more dbs i would really appreciate an answer cause i cannot align them.
