Thanks for the info!
Yes i have them here for a while to try some modding.
A friend asked if i could replace internal cabling, add some bracing and possibly swap some crossover components for higher quality ones.
Has anyone ever modified a Focus 140 and is willing to share his experience?

There is old thread in one forum about upgrading Focus 140.
There we follwowing changes:
tweeter -> Morel MDT30
original crossover -> match new tweter + better caps
Internal wiring.

Here is schematics from original crossover:

I suggest the following for your Focus:
C1 -> Auricap XO 4.7/200
C2 -> Auricap XO 10/200

The rest capacitors you can try Mundorf MCap400
Bass network: try both - Mundorf and original - it could be that electrolytic can give some "disdetalisation", which you could like more, as polypropelene caps could be to "clean" there.

Internal wiring: replace it to Audience Auric Hook-up - in upgrade I've mentioned owner reported that replacing wires brings positive changes.
