17.1.1. Typical impedance (Z) values

The following table indicates typical impedance values in ohms for

d&b loudspeakers. With correct measurement conditions and

relatively short cables, measured impedances should be within a

range of ±20 % of the values indicated in the table.

The values refer to a single cabinet. When two cabinets are

connected in parallel, the total impedance is halved, with three

cabinets it will be a third and so on.

Note: Please note that the LF values were determined by the

amplifiers' measurement algorithms using sine wave signals. A

DC resistance measurement using a multimeter may produce

different results.
10D/30D 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..
