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).

The X

is calculated as (L
vc
- H

)/2 + (H
ag
/3,5), where L
vc
is the voice coil length and H
ag
is the air gap height.
