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.
