Notes:

1

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

2

Program power is defined as power capacity + 3 dB.

3

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).

4

The X

is calculated as (Lvc - Hag)/2 + (Hag/3,5), where Lvc is the voice coil length and Hag is the air gap height.
