High efficiency 30 cm wide range unit, paper
cone, basket and ring = bronze without lead
SN12, pole pieces made of very mild steel < 0.20 %
carbon in a pot shape with central ALNICO 3SC magnet : all
fields is in the gap and magnetically proof ( TV… )
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 ) .

| These 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. |
