Filter component quality - do expensive coils and capacitors matter?

[nicoch58]

if you are DIY 's try and see ... we all start in this way !

PS
10$ for two caps in the tweeter

The Kef LS50 shares nothing in common with the Diva Simone speaker kit that you are considering, according to your earlier post.

The Diva speaker kit is 408 euro per speaker, so not a cheap kit at over 800 euro per pair, as you still have to build the box, or have the box built by someone else. The 110 euro extra for the "high end" crossover parts seem to be just the accumulated cost of the parts. Your choice is really how much the extra 100 euro matters to you. You will likely be very pleased no matter which way you go.
You will have more money decisions later on with the box and it's finish. So be sure to keep that in mind too.

I've changed my mind from the Diva Simone to the Samuel HQ along the way as mentioned some posts ago

Bausatz Samuel HQ – Heissmann Acoustics

I'm not considering the LS50's, I just brought them up because I found a pic of their filter/crossover which seemed to use cheap components, and I found measurements of them before and after component modification.

Good choice.
Choosing a speaker to build if often the hardest part.

use the scanspeak tw maybe a little better ...
use his xover , but as is microphonic put not in but outer ...after enjoy some music.... try x fun caps/resistor recipe ,we are diyAudio user btw and report back please

I guess upgraded inductors wd change the response.. do you have a link?

Measurements before and after upgrading can be found here:

Kef LS50 Crossover upgrade - DIY Audio Projects - StereoNET

It seems to have a positive effect, but comes at a price - about 80 euros in components.

Attached the before and after (filter component upgrade) measurements:

That's the result of redesigning the filter with the use of simulations and measurements. You will not get that by just replacing parts with more expensive ones.

Ah. My bad
