RE: Yamaha S6215HT-3 Speaker System

Bonjour Dominique,

C'est que tu souhaites articulés ton pavillon et ton tweeter ?Big Grin

Il semble qu'un tweeter soit désaxé dans le plan vertical et pas l'autre.

La réponse a ton interrogation : je connaissais la réponse, mais je ne voulais pas polémiquer à ce sujet.

C'est OLSON et H.NAKAJIMA, 2 acousticiens japonais qui ont fait des recherches sur la position d'une membrane fictive ou image fictive sur différents diamètres de pavillons.

Page 189 dans le HP de Jean HIRAGA.

Sur un pavillon circulaire cette image serait située à 80 % du diamètre de l'embouchure.
Mais au-dessus d'une certaine fréquence, cette image recule de XX et ce aussi pour certaines formes d'expansion.

Il y a une grande similitude av le plan de positionnement proposé.

Eric
