    A DC resistance measurement using a multimeter may produce different results. D80 amplifiers apply audible low level signals in the low frequency range for a few seconds using dedicated frequencies for each cabinet type. This reduces the impact of ambient temperature and mechanical aging of the driver components on the impedance values.
