Maximum Displacement, Xmax***               9.5 mm           Program power is defined as the transducer’s ability to handle normal music program material.
Displacement Volume, Vd                    1164 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             2.3 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
