Do Old speakers means Bad speakers?

[rwnano]

I have recapped, some old speakers from 90s and these are my personal experiences.

1. Companies, who want their speakers to last long - they use MKP/MKT film capacitors throughout their circuits. They are more expensive in general
2. Companies who want to play safe uses MKP/MKT before fragile components like tweeters and use electrolytic caps for the rest of the filtering.
3. Even after 30-40 years a good quality MKP/MKT capacitor would retain its capacitence. Hence replacing them with new ones of the same value would not make any difference in sound.
4. Companies who want to cut cost uses electrolytics all through their circuit and if you pick up one of them, you need to change all of them to new electrolytics or MKP/MKT if you want them to last longer. On changing these, there will be a dramatic change in sound to the intended sound from the factory.

Can you please give me some feedback on this crossover network? Thank you for your kindness and support

Unless you take it apart and measure, you wont know if its still 10MFD. Since they are electrolytic and if they are older than 15 years, replace them with Film capacitors. This is a very basic crossover(not a bad thing, if the design only requires this much to sound right!), so wont cost much to replace them.
