When it comes down to it, you would have to model the entire crossover network (bass, mid & treble) to see how well the drivers integrate.

Above my pay grade I'm afraid!

Looking back at your first post, you don't actually say what you find wrong with the performance of the 8 ohm version of the midrange driver.

You mentioned that a 'Wilmslow Audio crossover' gave a worse result than the original manufacturer's 16 ohm midrange crossover.

That begs the question - in what way is the replacement 8 ohm midrange speaker underperforming when used with the original 16 ohm crossover?

Why not accept the help you've already been given and physically try out Datsun's crossover modification to see if it remedies matters?

I already experimented with this design by dividing and multiplying components and the best one sounds great and putting the 15uf capacitor and not the 4.7uf capacitor is not because if it is not superior.
Would I have to put the 4,7uf is my question?

There appears to be a problem of communication here, perhaps due to language differences.

It is not clear which crossover version you think is 'best'.

Also, if the 'best' crossover 'sounds great', what is the problem?

We need a drawing of this 'best' crossover, including the component values.

Then perhaps we will better understand your question regarding the 4.7uF capacitor.

I think I understand now, but correct me if I'm wrong!

It seems that you have used the 15uF capacitor instead of the recommended 4.7uF one because you think it makes the crossover sound better.

If that is the case then stay with the 15uF capacitor. You don't have to use a 4.7uF capacitor just because the rules say so. Often, breaking the rules gives the best result!

I haven't tried the 4.7uf one, I'm just using the one in the scheme.
I don't know what the result would be to put half the capacity of the original scheme of Galu

4.7uF is the recommended value to use in the crossover circuit you show in post #26.

Just try it, you won't break anything!

What more can I say?

Default Crossover proac ebs

I think that you are living the value of the twteer 4.7uf and not the medium that is 15uf
