Service Kit

  • RCK15SW1004
  • 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 2V for 4 ohms Nominal Impedance.
  • Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
