Program power is defined as the transducer’s ability to handle normal music program material. Maximum Displacement, X max *** 6 mm ** T-S parameters are measured after an exercise period using a preconditioning power test. Displacement Volume, V d 350 cm 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, L e @ 1 kHz 0,9 mH *** The X max is calculated as (L vc - H ag )/2 + (H ag /3,5), where L vc is the voice coil length and H ag is the air gap height.
