Voice Coil Inductance, L e  @ 1 kHz         1,2 mH           *  The  power  capaticty  is  determined  according  to AES2-1984  (r2003)  standard.  Program
power is defined as the transducer’s ability to handle normal music program material.
** 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).
*** The X max  is calculated as (L vc  - H ag )/2 + (H ag /3,5), where L vc  is the voice coil length and
H ag  is the air gap height.
