Notes:
* The power capaticty is determined according to AES2-1984 (r2003) standard. Program power is defined as the
transducer’s ability to handle normal music program material.
** 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   [Hz]
loudspeaker has been working for a short period of time).
Note: On axis frequency response measured with loudspeaker
*** 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   standing on infinite baffle in anechoic chamber, 1W @ 1m
height.
