(1)Rated Power measured with 2-hour test with pink noise signal, 6dB crest factor, loudspeaker in free air, power calculated on rated Zmin.(2)Power on Continuous Program is defined as 3dB greater than the Rated Power. (3)Calculated byThiele & Small parameters, for SPL average in box refer to frequency response.(4)Thiele & Small parameters measured with laser system afterpreconditioning test. (5)Measured with respect to a THD of 10%. (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.
