Dynaudio New Confidence 20 Remade with measurement

[Hac]

Dynaudio's Confidence 20 use Neotec midwoofer and Esotar3 tweeter seems need a waveguide～ And then I Remade this box.The new woofer's Neotec technology makes the bass looks very excellent.（Of course，I improved the crossover）

In addition to measurements and drivers.

Welcome to ASR. Can you share details of the crossover changes? Also how it measured before the upgrade?
Is the change something you did DIY for yourself and can share with others, or do you have commercial interest and will sell the upgrade?

Great stuff. What I don't understand is what this has to do with the Confidence 20? It doesn't look like it, is has different drivers and crossover. Only the name Dynaudio is the same. What am I missing here?

Nevertheless, this looks like an excellent result!

In order to facilitate the installation and debugging, I re-made the baffle plate and cover rings. The tweeter unit has been reconstructed with a waveguide panel replacing the original panel.Both tweeters and woofers were removed from the Confidence 20.

It's DIY for myself. I can't get more drivers of Confidence 20.

Do you have the confidence measurement to compare?

I did not measure original confidence 20. Stereophile has measured confidence 30,seems not too bad.

Hac, really nice job,
I didnt understand if the mid basses are the original and the tweeter is original with added waveguide like in confidence 30-50 -60 ?
I just bought a pair which seems one of the esotars is not functioning properly -( and I have to buy new one if dynaudio does not approve warranty, So I am thinking making something like yours ( if the units are the same of course ) , which seems really nice .
I am attaching the not perfect measurements ... the gray is 3rd harmonic , one is woofer only .
Will appreciate really highly your opinion and knowledge.

Can you post a diagram of the original crossover? I can post the xover schematic from dynaudio heritage special.
