Each driver part is controlled and measured all along the manufacturing
process . Each driver is put under a very serious pre-running and
then measured in order to match pairs with max tolerance delta as
0,2gr. on mobile equipment mass, 0.1 Ohms on d.c. resistance, 2Hz
on resonance frequency, is numbered and life guaranty ( first owner

characteristics have an indicative value and are only the result we
have in our deaf anechoic chamber from measuring equipment actually
in our possession. It always must be kept in mind that the main ones,
as the natural, equilibrium, musicality, cannot be described above
but are only partly derived from them. |
