Service Kit

  • RCK12PS1008
  • 2 hours test made with continuous pink noise signal (6 dB crest factor) within the range Fs-10Fs. Power calculated on rated minimum impedance. Loudspeaker in free air.
  • Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
  • Applied RMS Voltage is set to 2.83 V for 8 ohms Nominal Impedance.
  • Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
