Effective Surface Area, Sd (m )            0.088 m 2         Program power is defined as the transducer’s ability to handle normal music program material.
Maximum Displacement, Xmax***                10 mm           **T-S parameters are measured after an exercise period using a preconditioning power test.
Displacement Volume, Vd                      836cm 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, Le @ 1 kHz           3.45 mH
***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.
