Got here from Nelson Pass's video on the Audiophiliac, and boy is the DIY bug stirring within ever since!
As a first project, I decided to upgrade the crossovers on my Paradigm Prestige 75f's to DIY ones with higher quality components with stock values.
Some preliminary questions:
1. Any tips for reverse engineering the board using a continuity meter?
2. After the schematic is in hand, how do I choose between the different caps\coils\resistors brands and models?
Since this is my first time DIYing crossovers, any relevant tips will be appreciated.
Thanks in advance 🙂

He didn't, I was curious regarding the avid DIY community he mentioned in the vid. Very happy to have found this gem.
@PeteMcK,
Can you please elaborate? Don't you think replacing everything (i.e., the resistors and inductors as well) would sound better?
I think you misunderstood my intention. I'm not upgrading due to deterioration, the stock c/o functions properly, I'm aiming at improved sound quality.
We do understand your question. 😉
You might like to learn how to choose the right speaker for your situation, how to set it up physically, how to voice it electrically.

Thanks for replying. The speaker in my case is a given, in terms of physical placement I've experimented a-lot and I'm rather happy with my current setup (New record day on youtube has a good tutorial). Voicing electrically - now we're talking 🙂 that was my intention in Q#2 regarding LCR synergy and character. I'd love to hear your thoughts.
@PeteMcK
Could you please elaborate regarding tools & MO?
changing caps to more expensive ones with same value will probably not change anything about sound, but will not deteriorate sound either. edit: some people claim they can hear differences between cap types and brands ...
same for changing inductors to ones with same inductance and same resistance. changing inductors to expensive low resistance ones may severely mess up the crossover.
so trying to improve the crossover is probably really difficult and would only make sense with proper measuring equipment, imo.

I think the same, the only way to make it better is totally redesign the crossover of that speaker based on measurements. Just replacing stuff with more expensive parts will in the best case sound the same, mostly it's worse as the balance made by the designer is of by different ESR and so ...
And to be honest, Paradigm today makes very flawed speakers, their measurements of other models of that line show that their frequency response is all over the place, so redesigning the crossover may be a good id, but then from start (measurements of the drivers in the box).
