1

2 hours test made with continuous pink noise signal (6 dB crest factor) within

the specified range . Power calculated on  rated minimum impedance.
Loudspeaker in free air.

2

Power on Continuous Program is defined as 3 dB greater than the Nominal rating.

3

Applied RMS Voltage is set to 2.83V for 8 ohms and 4V for 16 ohms Nominal

Impedance. Average SPL from 200 to 3000 Hz.

4

Thiele-Small parameters are measured after a high level 20 Hz sine wave pre-

conditioning test.
