Hobbs!!! My buddy! Lol.
So, that’s an awesome chart about the inductors! This is very important for placement! Think of these things as a producing a force field of interruption when sitting the wrong way! Hobbs photo will show you exactly how to place them! Again, very important step! Normally I always lay one down.. and the other is a couple inches away, and I make sure it can roll into or roll away!
This way the magnetic force fields are opposing Each other and not interfering with each other. Magnetic fields cause issues!
Umm, the wire you are using!? What is that exactly? I would suggest another wire that’s a bit better suited for the network. You don’t want to bottle neck your signal path.
I don’t have the schematic handy, do you? can you post that so I can see. Looks like maybe you have some caps in parallel that I would put together possibly. And that’s a lot of wire you got there.. again a I would use a better wire. Those caps seem to be a Electrolytic non Polll to which are ok.. not the best. Coils look decent quality.. That sandblock resistor needs to go, just a suggestion. Lol.
Maybe even due away with that xover board and use another so you can tie the wires and leads together without using a hole and a tiny bit of solder. Does the board have actual trace on it? (Signal path copper lines on the board) of so, I would die away with that board all together and use a simple piece of MDF. Twisting all components together then soldering.
A lot of information to take in. But this is DIY, and your learning so much more then others that just run to the store and purchase a set of speakers! Feel accomplished!!! Your doing the work! Your ears will thank you later!
Also if you can use one wire for your ground.. sadly with this photo I can’t really tell.
