RE: Besoin d'aide concernant les différents 515-G de GPA
Les données ne sont pas forcément fausses mais mesurées après un pré-conditionnement
Exemple pour un fabriquant:
**T-S parameters are measured after an exercise period using a preconditioning power test.
The measurements are carried out with a velocity-current laser transducer and will reflect the long term parameters (once the loudspeaker has been working for a short period of time).
et pour un autre:
6) Thiele - Small parameters are measured after the test specimen has been conditioned by 450 W AES power and represent the expected long term parameters after a short period of use.
