Hello all!
I want to recap caps in Hi and Mid ranges.
Please help with crossover scheme.
Thanks for any help.
Hi - for a full recap you'll need to replace 8 capacitors per speaker (C2 - C9): 4 x 47uF, 1 x 25uF, 1 x 15uF, 2 x 10uF.
I suggest that you upgrade your Beoworld membership to "Silver" (or "Gold"). This will give you access to the service manuals of Beovox M75 (and all the other speakers/turntables/receivers/etc.) - and the diagrams that shows where the capacitors are connected.

Oh, thanks for your comment,
probably it's better to replace them all.. But it could be rather expensive.
Sergey:But it could be rather expensive.
Only if you want it to. New electrolytic caps from US supplier will cost 12-13 USD for the 2 speakers here, the 25 uF is not available use 10+15 in parallel.
I have been using these in some of my speakers, good caps. Or order from Dillen (Martin) on this forum, also cheap and comes with installation instructions

Thanks for good urls!
I think it could be good and easy decision to replase all electrolytic with the same (electrolytic) type of caps, but I almost sure that in Hi and Mid circuits polypropylene will be much better for the result sound quality. Or I am wrong?
Martin's kit is also electrolytic only?
I have used poly caps in one pair of speakers, but cant hear any difference (my hearing is not the best) so I stay with the electrolytic.
Matins provide electrolytic, not sure if he can provide polys.
I haven't seen any measurements that can confirm that polys are better, the original caps was produced some 30 years ago, the caps produced today are better and closer to specs. the ones in the link are 5 % caps, the org. was 20 % I think.
Hello, Soren l
Recently I replaced old wires with cheap copper ones (1,5 mm2 for HF and 2,5mm2 for other).
Difference is amazing!!! You must try. After that you'll fill much more nuances (inc. caps), for sure!
