That is the level one crossover.
I sent pictures of it to Troels to review to see if I had fabricated it correctly. He said he could not review it because my construction was too poor.
Earlier in the process, I was asking where to find the information for the capacitors for the different tweeters. it was in an obscure chart. I think he got frustrated with me and told me that this was not a paint by numbers project and that I should get some help. (it hurt my feelings, so I deleted the email.)
How does it look to you?
I took my time. I tried to follow the drawings as much as possible, I tried to be neat.
It seems to be working fantastic.
I don’t think I’ll be building another set of speakers after these.
These are my 60th birthday present to myself. I turned 62 this past December.
The bright side is, now I can have my birthday party. I’ve been waiting to have a party until the speakers are finished.

My only comments:
- The coil placements do not consider this.
- That round thing inside the C-Coil in the bass section is hopefully non-metallic?
So you were saying that the coils from one crossover to the next are too close to each other and they’re probably interacting?
I don’t think there’s anything I can do about it at this point.
The thing in the middle of the coil on the base crossover is a cork. Although, there may be a stainless steel screw holding it down. Is stainless steel an issue?

Stainless is okay.
The 6 coils all laid flat could easily be fixed. Just rotate the end coils in one line and the middle in the other.

wolf_teeth, others,
From the image it looks like drjimwillie has limited depth in the space for the XO boards, and turning the bigger inductors on their sides might be challenging; hence have a proposed layout changing the orientation of the smaller air core inductors.
How does the layout look to you?

I added some numbers. 1-3 are probably as good as can be unless depth can be added to the crossover box.
4-5 not so good. 4 is looking at 5 and 5 is looking at 1. I suggest rotating 5 by 90 degrees and moving 4 to the right where the resistor is ( which can be placed above or besides the coil. 4 would then either be lying flat again, or standing and rotated so that it is looking at the space between 1 and 2.

I am sorry I did not reply to your most gracious advice.
First, I am in all of your editing skills. I do not have this skill.
I have read these two messages, probably 20 times now and went back to the linked information from Troels.
I will have to figure out how to make these changes.
I also realized that my other crossover is configured with the mirror configuration. I have to pull off the crossover cover to take a look at what needs to be done.
In the meantime, I have finished the dry fit for my server, and I have finished painting and detailing my car so I can put it up for sale.

Yes, I don’t know this Troels guy but he sounds kind of rude.
Anyway, inductance is measured in Henry, and a coil will generate a magnetic field, with the direction of your thumb, if you consider your closed hand giving the wrapping as the direction of the turns.
These magnetic fields will modify the inductance so it’s important to put them in a way which will not impact other components or each others.
This is what is shown in the webpage you linked, albeit in a somehow empirical way.
Tl;dr: coils will affect other coils or components, proper spacing and directions will limit this.

Troels is known to be in the rude side, but it's part of his charm I guess!

I think that answering 300 mails a day for the last 20 years can make anyone short in words and in temper. Bless his work
That's what counts!
For sure, lots more possibilities of getting it wrong than right.
Orientation and proximity both make small differences in coil inductance, which can make small differences in the speakers frequency response, which sounds amazing to you as they are presently configured.
To put it in perspective, any frequency response changes those small differences in coil inductance may make would probably be far less noticeable than adjusting the toe-in angle of your speakers, or changing their distance from the rear wall or fireplace, or the difference in sound of the same take of any song mastered by two different individuals.
