These french guys apparently visited Dynaudio's facility in Denmark, and shared their experience in both words and pictures. If you can't read french, I suggest you either use Google Translate, or just look at the pictures (watch out for the porn calendars, btw).
Nous sommes très heureux, Ludwig et moi-même, de partager avec vous ce sujet sur la visite de l'usine Dynaudio. Je vous souhaite pour ma part un excellent moment de lecture.
Petit mot d'introduction par Ludwig...
As you may or may not know, Dynaudio is a danish speakers manufacturer best known in the audiophile world for designing and releasing the Esotar tweeter, acclaimed as possibly the best tweeter in the world by critics and enthusiasts alike. After ceasing the sale of individual parts and drivers to DIYers to focus on the manufacture and sale of their own speakers, they stopped the production of the Esotar (now a rare and costly piece) and designed the Esotar2, which can be found on their higher end lines. Whereas some claim the original Esotar still has an edge over the Esotar2, all agree on the latter being the best tweeter currently available for its smooth, natural sound and revealing capabilities.
Dynaudio Confidence C4 on the left, and Dynaudio Contour S 5.4 on the right. The latter is slightly smaller than a medium sized man, and the Contour S 3.4 look like dwarves in comparison. This should give you an idea how big the Confidence C4 are (the Confidence series has double Esotar2 tweeters, by the way).
