I have pairs of Dynaudio drivers 30W54, D54, D28, D21 and 4 Variovents. I decided to use drivers on DIY project. Does anyone has plans/scheme how to make housings and crossover for the DAK 4-210 kit or do you have a proposal for some other DIY project?
Dynaudio DAK 4-210 - Zvučnici - diyAudio.rs
This dynaudio kit is not exactly the same by number as dak-4-210 (I can't see the difference), but the crossover df 4 210 is the same.

Aperiodic, thx a lot, but unfortunately photos are not clear enough to recognize values.
Aperiodic, hvala ti puno, samo veoma loše se vidi.

A single cap filter comprised of 2 caps in series as hp for D21.
A single cap filter and an Lpad for D28.
D54 unit hasn't got any hp filter section, a single inductor as lp and an Lpad.
2nd order filter for 30W54 ( appears 7x4,7uF in parallel). Must have been difficult finding a single 33uF.
This one would not fall under good quality crossover proposal.

@Makra28 - Sorry I noticed only now that you started the discussion I gave as a link
Next days I will see someone with a bigger collection of dyn documentation, post if find something.
Recently I made a dyn kit dak 3-210, and I really like it. It was in the basement unfinished 32 years. Never too late. Loudspeaker archeology, like Pompeii. The other one finished last year was a Jean Maurer two way, kind of reconstruction, active version (this one 23 years)in marble, not because I like the look, I don't. Thank you, covid-19.
@Lojzek, I never made any 4-way Dynaudio but really many two way and 3 way 12 db, 24 db, 12/18 etc. etc. Finally, and it was a kind of deception, I concluded that Dynaudio crossovers are the best solution for Dynaudio drivers. Even better than active (I never tried dsp). The construction of those old dyn drivers are a whole with 6 db crossovers. Kiss principle, I suppose.

It is a partial series-partial parallel crossover setup. The D54 has a highpass through the 33µF, the series coil on the 30W and the 30W itself. The scheme might be more clever than you thought.
@TS, these are the old domes I guess. D28 and D21 with small waveguides and D54 recessed.
