You will find my notes and pics on his builders pages.

I share the view that 4-way is unnecessary with these drivers. The 22W can go up to 400-500Hz easily and from here you can go with the 12W or a 15W to the tweeter.
Btw, the very low passive crossover in the 4-way can cause additonal problems which is not showed in your simulations. (See below)

Why you don't like 4 Ohm speakers? What is your amp?

Passive woofer crossover peaking issues

Yet another opinion that a 4 Way is not necessary or even desirable with an 8 or 10 inch bass driver. Most of the good 4 ways are designed more like a good 3 way, with the addition of a built-in subwoofer. If your low frequency driver was a 15 inch, then yes a 4 way might be an advantage over a 3 way.

Hi!, Alright.. Maybe the 4way was a bad idea afterall . Im currently rocking a hegel h90 but im actually planning upgrade that to something like a luxman or something similar.. TBD.. About the 4ohm i just liked the idea of 8ohm, not much more to it except it easier to drive on more widely variety of amps. In the end maybe 4ohms is the way to go in my case with perhaps a 3,5 way

Did you consider this option as you have a reference : Keep one as a reference.Take one of the tower with the filter outside with longer wires going outside from the BR port and work on it on a wood piece to adapt to your room, tastes & learning project ? (Ask anyway a little mic and soundcard investment).

Many people do it perfectly. In the link, the member made unusual choices.

Maybe, but for first time DIY? What is so unusual in the link that the member made? I didn't see any.
I still think that a 4-way is unnecessary with these small drivers but if someone wants a 4-way then it's his choice.

Nope Go 4-Way
But be prepared for a lot of time and effort if passive. 3-Way with powered subwoofers will clean up the midbass and really allow the midrange to shine
The question really is how fat is your wallet? Clean deep bass is going to be expensive, more than I can afford at the moment but I see nothing wrong with using 10" woofers as a mid-bass unit and going to 15 or 18" for the sub, crossing over as low as practical
I cheat tho, I use affordable Behringer crossovers for bass/mid-bass/midrange cross and fiddle with passive for the top
Please excuse the crappy photo and even worse woodwork/painting
