RE: Calcul d'un adaptateur rond-carré pour TAD2001 et ARAI A-290 FL
Pour ceux qui ne veulent pas lire tout le post sur le 6681 :
"None to my ears, as those are basically the same drivers. most of the small differences were because of the horns (1.4 inch for the 6681 and 1 inch for the 6604).
In fact, you can consider that the 6604 is the same driver as the 6681 if taken with a 1" 1.4" adapter. And with a less beautiful casing.
The problem is, the 6604 is maybye even more rare than the 6681. Never seen one on the internet, except those I bought.
The 6604 shares all the mechanical parts with the 6603, only the diaphragm is different. The 6603 sounds extremely good, and I think that it is an underrated driver. It is as good as the JBL and Altec phenolic horn drivers, for a fraction of the price (considerig you can grab a pair on ebay for less than 150$ when it shows up)."
