Displacement Volume, Vd 1178 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 @ Zmin 2.1 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 0310 the air gap height. 056
