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: Thiele & Small 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. 7: Drawing dimensions: mm 8: The notch around 400Hz on the frequency response is typical of the measurement on IEC baffle
