Notes:

* The power capaticty is determined according to AES2-1984 (r2003) standard. Program

** 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.
