See picture..
The others were better IMO (with respect to the coil placement). yes the left coill should be turned 90deg then it should not cause issues. if you have them in their original positions AND turn the left one on its side and at 90 degrees then the chances of interference will be virtually nill however even at fairly close quarters with the coils at 90 degrees to one another (rule of thumb you should not be able to see another coil through the hole of a coil) then they should be ok.

My recent crossover has the coils quite close together. Troel's indicates (in his experiments) that 20cm centre to centre is enough spacing even if mounted in the same orientation.

Ok, I have not soldered it together since I had a problem with it beeing too tight. You prefer this one (pic)? The only bad thing is I need 2 wires to connect it with. But I can use the same layout and put the components a little closer to eachoter and using you coil orientation advise. And I will lay the big one down west-east to make it more secure to the board.

This should be good. I can use the lead from the capacitors to the right going south to common and only use one wire at the bottom.

oh I only just realised the tall thin thing is a coil, I thought at first it was an electrolytic cap I think you should be fine with that coil orientation. just for reference, here is a link to Troels test's on coil orientation, at the end it shows the recommended placements. Placement of coils in crossover networks

I drill the wooden boards and fix with tie wraps in such cases. 2 pairs of holes along a big pp cap axis fix it pretty well. Because something maybe changed to taste later.

Thanks for your concern Salas, I will use a glue that is flexibel and can be removed with a sharp knife. Troels Gravesen uses the same (Placement of coils in crossover networks) on this site. And yes I will go easy with the glue using only so much needed, the big coil needs rather much I guess but otherwise it will be small amounts.

Yes, just as Salas was saying, I was just thinking of adjusting to taste.
