Well I finished my 3 ways and they sound AMAZING
I want to thank everyone here that helped me out as I definitely could not have complete this without all your help. At least not to the level of polish that it is what it is.
A special thanks to A4eAudio for guiding me through this. He gave me a lot of one on one help and I don't think I could have navigated all the software without him.
The REW screenshots show the end measurement far field. I am using the IR window to show with and without reflection to I can show how flat the frequency response ended up. The second REW measurement is all the way down to 40 hz. By then the reflections of the room have taken over. I built some acoustic trap to put on the back wall so that should help. The traps are 4" rockwool laid on top of acoustic underlayment. They will be placed 2" from the back wall on stand offs to help trap the lower frequencies.
As you see in the first pic I am using these in my main living room. I am not used to having this good of imaging so am getting used to the fact that I can now hear, for example, the singer on the right, the bass player on the left, and that the drums are more left and behind both of them. My buddy mixes music and says these have the best imaging he has ever heard. I never once took imaging into consideration of my design so I guess its a happy accident. If anyone knows why these have good imaging let me know so I can replicate it in future designs.
I am running them off a WIIM amp. It sounds very good. I also bought a brand new receiver to try out but that thing sounds super flat and not very musical so it will be going back to the store.

This occurs when the frequency response from the left speaker is equal to the frequency response from the right speaker.
I am glad they turned out well! I think this was a pretty cool display of how willing people on diyaudio.com are to help. A lot of the time, the original poster realizes they need to put time and money into actually measuring the speaker and the thread quickly dies off. In this case, you measured, asked questions, measured some more and several people took your measurements and helped with xo questions. It was awesome to follow along.
I mentioned this before (as did Wolf), but that driver combo of the HiVi RT1.3 tweeter and Zaph midrange combines two drivers with a LOT of sound quality for the money. It is 3-hour and 45-minute drive from Chicago to Plymouth, MI (west side of Detroit). You should bring these to the CSS Detroit DIY get together Sept 28th.

A4e,
I might actually come out for that. My wife's sister lives right over there. Is it just a get together or is it a competition?

Just a get together. Hook up your speaker and play 5 minutes of house tracks and 5 mins of you own demo music. Tracks are usually 45-60 second clips of songs. If you don't have your own 5 mins of tracks, you can borrow someone else's. Probably 20 to 40 people...listen to speakers and hang out and talk about speakers. I'm sure people talk about other stuff than speakers, but I have a speaker problem. 😛
The 1.2mF will filter out the infrasonic low frequencies quite well, helping to reduce unwanted woofer excursions below about 20Hz.

I think we should redesign the box and make it sealed. No, wait.......let's try some passive radiators. Have you stuffed the ports?
All kidding aside, nice work on those boxes. I'm guessing that you're going to be hearing things in music that you've never heard before. Enjoy!!

Oh man so many people wanted to remake the boxes lol.
I can decipher which songs were recorded with good or bad recording equipment now so thats new
I would wire an SPST switch across it, mounted to the rear panel or ran through the port. This way you can defeat it if you want to try both ways.
Just to clarify, that is a 1.2k uF cap, 1.2mF, or 1200uF. Remember that has to be nonpolar electrolytic, or a pair of polarized 2400uF back to back in series, or a VERY large poly like these:

I ordered these guys here. Did a bit of research and found out Elna is a great brand. 35V only so IDK. I didn't realize voltage would just that high. Usually audio stuff stay pretty low. If it did jump to 200V it might arc across my terminals.
My XO is removeable. I just unscrew it from the back and it pops out sort of. It has a sealing gasket. I'll show a pic of the cad. It seal from the inside so the bass pressure actually forces it into the gasket rather than trying to push it out of the cabinet. See that the inside is large than the outside.

Attention, seems they are polarized.
Or did you plan to connect them parallel-series?
Then you have (about) double the voltage rating - if i'm not mistaken.

STV,
Hmmmm.... So they have to be non polar, non inductive, 1200uf, and take over 100V?
Going to be harder to find than I thought....
I did find some on digikey but they were 20% tolerance which I considered to be too high of variance for the application.

The 1100 I showed a pic of are poly, 400V, low ESR, nonpolar measured at 1142uF, and only $45 each on Ebay.
They just happen to be huge!
