gosh sorry, somewhere deep down I knew that but this info did not surface in the moment.

I forgot to tell you that the W6-1139, an 83dB 4ohm driver achieves 95dB at 34Hz at 2.83vrms at 1meter. That's quite some horn-gain there. 🙂
There’s several pdf plans in the thread that we use to scale up and down. The one by Planet10 is closest to original design. There are others with smooth curves etc. You will have to use search feature as I don’t have it off the top of my head.
But given that you get no gain, mid/top, and if wall mounted no need for BSC, you’d have to EQ it all back to match the midrange output.

Then you won’t be using the front output at all, possibly worth exploring burying it into the box,

Need Proper Gluing
Hi Friends, Since been following all great threads of great minds.
Gave a try to my self, to come out of audiophile category to audio creator category. Just prepared a cornu for myself.
Problem i am facing here is that how to glue wooden spiral edges to back wooden ply sheet ? any leakage will spoil all efforts ?
i am using Audio Labs 4 inch driver, along with the combination of fountek ribben twitter.
Fountek Ribben Twitter : RD1.0
Audio Labs Full Range Speaker : 2PCS Audio Labs High Quality 4inch Full Range/Full Frequency Speaker Driver Unit Shielded Paper Cone Aluminum Bullet 4/8ohm 25W -in Speaker Accessories from Consumer Electronics on Aliexpress.com | Alibaba Group
Along with a ceramic capacitor of 4.7 uF for high frequency pass.
I am also interested to know quantity and positioning of accoustic wool, if in case to be used to enhance performance.

What I am thinking at this point is to build a shallow open-backed box to place over the woofer opening. That box would contain all the drivers and would have an angled baffle to allow for toe in or out, or even up and down depending where on the wall they were placed.
That or just place it back firing on the wall and add a satellite system.
Just at the thinking stage right now but I am going for a drive and if I happen to come home with a box of foam core... 🙂
There are a number of different ways that have been succesful. Have you had a chance to read through yet?
May not need the tweeter.
Too big. I am think be tween 2.2 and 1.0 µfd will eliminate more overlap. You might also need a resistor or L-Pad in there.
This is trial and error. No way around it. I use mineral wool, others use things like polyester, felt or WHY. I have always found that filling the compression chamber behind the driver and adding into the horn throat as needed from there works best.
Good luck
And judging by the only picture I have of you... (mustering up my best Billy Crystal voice)

Hey X, what are the pros and cons of making the cabinet 4 7/8" deep to better fit the driver?
You can do it, it will make the bass have a peak overshoot at 34Hz rather than flatter. But maybe you are ok with that?
