Descrizione

Rated Power measured with 2 hours test with pink noise signal, 6dB crest factor, loudspeaker in free air, power calculated on rated Zmin
Power on Continuous Program is defined as 3 dB greater than the Rated Power
Sensitivity calculated by Thiele and Small parameters, for SPL average in box refer to frequency response
Thiele and Small parameters measured with laser system after preconditioning test
Xmax measured with respect to a THD of 10%
Xvar value corresponding to a decay of the Force Factor, or Compliance, or both, equal to the 50% of the small signal value.
Due to continuing product improvement, the features and the design are subject to change without notice.
