This is the part # from Eminence, the makers of the speaker.

The price from Klipsch is really very good. I would be hard to find other speakers with an Xmax like this.

[Vinc]

As I understand it, Klipsch used the following K-33 bass drivers during the years indicated:

K-33-J Jensen (round AlNiCo magnet) April 1960 to 1962 (however some forum members report these may have been used as late as 1967)
K-33 Electro-Voice (square AlNiCo magnet) pre-1962
K-33-M Eminence Speaker Corporation? (AlNiCo magnet) Sept 1967 to (Bob Gault left CTS to form Eminence in 1966 and expanded in 1972)
K-33-P Chicago Telephone Service (CTS Corporation), Paducah, KY (square ceramic ferrite magnet) January 1968-1975?

(please correct me if I am wrong and I will edit the above information for everyone's future reference)

oué bon y a eut du mouvement dans les HP

[Vinc]

j'arrive pas a bien comprendre tout sur l'enceinte a pavillon...
la charge acoustique est le pavillon ou l'arrière du HP?
le pavillon joue le rôle d'adaptation d'impédance acoustique ca j'ai bien compris. mais sur quel paramètre du HP s'appuie t'on pour calculer?

[LeTOF]

La charge doit être la partie arrière,la partie avant serait plutôt un résonateur (pour augmenter le niveau)....
Enfin je pense
A l'occasion,t'as pas les spécifications du K22 ????
