What you see it almost complete for low and midrange 1st order.

I see the three coils so why thy for a first order
it look like those two capacitors are the same value

coil with core in sries with sub. two capacitors parallel; in series with flatwire.
Coil with ferritecore is impedance correction for mids second order or zobel I have to try. Otherwise they wouldn't have damping at all.

I have mounted the filter board on the backplane of the box.

It is premature I have to measure and listen if I have to improve it.

Beautiful work, Helmuth! They look terrific! Very professional looking - like something you'd find in a studio. How do you find the sound? Something about those woofers makes me think they'd sound nice and tight, though I know you can't tell much from looks.
