RE: Yamaha S6215HT-3 Speaker System

Bonjour Pascal,

A vrai dire, je suis un peu perdu... Le démarrage de l'impulsion, si on le prend en référence, est le même pour toutes les frequences reproduitent par un transducteur donné.

Pour chaque haut-parlour filtré, la phase et le délai de groupe varient. C'est spécialement vrai pour le pavillon de bas medium dont la phase et sa derivée, le délai de groupe, varient très vite à l'approche de la fréquence de coupure basse du pavillon.

En terme de retard, et considérant le deuxième paragraphe, je ne comprends pas pourquoi l'alignement sur les base des impulsions permettrait d'optimiser le raccord en phase à la fréquence de raccordement, sachant que le délai de groupe peut provoquer un retard de plus de 20 cm...

Il me manque certainement un élément pour intégrer tout ça...

Cordialement,

Dominique T
