Maximum Displacement, Xmax***                7.5 mm          *The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer’s ability to handle normal music program material.
Displacement Volume, Vd                     918 cm 3         **T-S parameters are measured after an exercise period using a preconditioning power test.
Voice Coil Inductance, Le @ 1 kHz            1.9 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.
