I don’t remove any wires at this stage.

I only pace the filter at the top of the cabinet and do the work here. I suggest using some protection between the filter and your Beovox 5000.

The process require a few changes to the filter because the new caps are physical much bigger and more heavy.

I will rearrange and I will use hot melt gluing of the caps.

  

This is the result of the rearranged part for the crossover filter.

The reason for gluing the parts is of course avoiding noise and vibrations.

more to come 🙂

Sure looks crowded, I dont see the 3rd coil, is it hidden under the 68 Mu cap, and did you glue the cap to the coil ??

Yes, the 68uF cap is glued on top of the coil and to the other 68uF cap.

If you had to take it out again, wouldn't the glue damage the coil ??

By the way I use transparent silicone for gluing, it takes longer time to set, but is easier to clean of and more flexible when dry, the glue from the heatgun gets very hard.

Please have a look at the photo of the filter "before" upgrade (2.nd. photo on this thread) - you will see the the "pertinax" washer on top of the coil.

Everything I've read over at diyaudio.com would lead me to believe those two inductors (coils/chokes) are too close together and should be separated to prevent magnetic field interferences.
