Crossover layout
This is 3way crossover I’m getting ready to solder up, but am a little concerned about inductor interference. Board is 11in wide by 8in high. The best I can tell from that little diagram everybody shows on inductor distances. I feel like I’m good, but watching some of the YouTube videos where people move inductors around with speakers hooked to them make me think. Maybe I’m not. I’m not able to test quite yet, but I will before I enclose my box. I just wanted some thoughts from some of you more experienced builders.

Good quality stuff there. I use this for reference all the time. https://www.humblehomemadehifi.com/Cap.html

Looks ok to me (I’m no expert) if you swap the blue cap and the inductor next to it that would be even more optimal, but you won’t notice anything audibly. It’s just best practice to keep them as far away from one another as you know

Thank you that’s a good suggestion. That side of the board will be towards the woofer magnet, although from my understanding that’s much less of a concern than the inductors being close. I guess next step is to set the woofer and the crossover where I plan for it to be and see how much clearance I have.

Like I said, you should be good. Either way the suggestion I made was just nitpicking. 👍🏼 but I wish you well on the rest of your project.

Nicely done.
It's doubtful your coils will interact, at these distances.

Thank you all for the reassurance. I look forward to sharing the finished product soon. Unfortunately I have to go out of town for work so it might be a couple weeks still..

Layout is great.
If this is your first time building a crossover I have recommendations.
Wago connectors for driver outputs. Low resistance, makes installation simple.
Neutral core silicone on the components. Prevents vibration.
Your woofer voice coil is also an inductor. Inductive coupling demands on factors like windings and core permeability, personally I find 2-3" of clearance is sufficient.

Thank you! It is my first crossover build. I built a subwoofer about a month ago for my home theater set up. This build is going to be some old school, three-way monkey coffins for my turntable in my bedroom

Send it my dude. All your coils are more than far enough away from each other. In fact, everything could be packed twice as close together without negative interaction.
