Effective Surface Area, Sd (m )            0.055 m 2         *The power capacity is determined according to AES2-1984 (r2003) standard.
Maximum Displacement, Xmax***                10 mm           Program power is defined as the transducer’s ability to handle normal music program material.
Displacement Volume, Vd                     550 cm 3         **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
Voice Coil Inductance, Le @ 1 kHz           3.25 mH          term parameters (once the loudspeaker has been working for a short period of time).
***The Xmax is calculated as (Lvc - Hag)/2 + Hag/3.5, where Lvc is the voice coil length and Hag is
the air gap height.
