Service Kit

  • RCK320KC16A
  • 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 4V for 16 ohm Nominal Impedance
  • Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
