Description

 

  • 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.
