THIELE-SMALL PARAMETERS 4

Notes:

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

2 Program power is defined as power capacity + 3 dB.

3 Sensitivity was measured at 1m distance, on axis, with 1W input, averaged in the range 1 - 7 kHz

4 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).

5 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.
