THIELE-SMALL PARAMETERS*
MOUNTING INFORMATION
*
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 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 the air gap
height.
