Note:
1 : Rated Power measured with 2
hours test with pink noise signal, 6dB
crest factor, loudspeaker mounted on
enclosure
2: Power on Continuous Program is
defined as 3 dB greater than the Rated
Power
3: Calculated by Thiele & Small
parameters
4:

parameters
measured with laser system without
preconditioning test
5: Measured with respect to a THD of
10% using a parameter-based method
6: Value corresponding to a decay of
the Force Factor, or Compliance, or
both, equal to the 50% of the small
signal value.
