How to design a crossover board from a schematic

[HwaLF]

Hey there. This is my first time building and designing a real speaker, and I’ve been pretty confused about how to make a crossover board from a schematic. Luckily, there’s someone who’s been helping me out a lot, both with the crossover design and with doing everything correctly. So here’s my first attempt at a layout (just for context - I don’t mind how it looks or how much space it takes up). PS: These aren’t actually the values I’ll be using - they’re just parts I have on hand. I’m trying to make the layout first. I’d really appreciate any pointers or advice, thank you!

You might find pegboard and cable ties useful for the actual crossover build.

(That's an early version of the crossover for one of my bass guitar cabinets.)

Things to consider for PCB layout:
- Absolute max current - affects trace width and copper thickness selection
- Absolute max voltage - affects min separation distance between PCB traces and connector pins
- Physical robustness - if heavy inductors, power resistors or capacitors are used, they should be anchored to the PCB by some combination of silicon adhesive (RTV), tie wraps going through holes in the PCB and around components. Like Dukes post above.

Probably doesn't make a difference, because you have good spacing, but typically try to avoid "pointing" the holes at each other. Consider rotating the 1.5mH inductor 90 degrees.

Oh thank you for the heads up! I'll keep that in mind. Do you think this layout is the correct translation of the schematic? I can't figure out if my layout is correct or not according to the schematic
