Efficiency, ? 0                               3,3 %
Effective Surface Area, S d                0,088 m 2         *  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.
Maximum Displacement, X max  ***              6 mm           ** T-S parameters are measured after an exercise period using a preconditioning power test.
Displacement Volume, V d                   350 cm 3          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).
Voice Coil Inductance, L e  @ 1 kHz         0,9 mH
*** 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.
