Effective Surface Area, S d                0,088 m 2          * The power capaticty is determined according to AES2-1984 (r2003) standard. Program
Maximum Displacement, X max  ****             6 mm            power is defined as the transducer’s ability to handle normal music program material.
Displacement Volume, V d                   350 cm 3           ** Sensitivity  was measured at 1m distance, on axis, with 1W input, averaged in the range
1 - 7 kHz.
Voice Coil Inductance, L e  @ 1 kHz        0,95 mH
*** 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.
