Where Z1 is the impedance (or ohm rating) for the first speaker, Z2

for the second, and so on, for every speaker in the chain. This

equation calculates the total impedance of the speaker system,

which should NOT be lower than the minimum impedance rating of

the amplifier.

Z(Total)=

EXAMPLE 1:

For one pair of speakers use the short form of the equation: the

product of the two speakers divided by the sum of the two

speakers is equal to the total impedance or the equivalent

impedance of the speaker system.

This equation may be used to calculate the equivalent impedance

for additional speakers in two-speaker increments. Determine the

impedance of the first two speakers, substitute Z total for Z , and

include the next speaker. Repeat the process until all speakers

have been included. The result should be the same as with the first

method. A word of caution: polarity rules must be observed when

connecting multiple speakers. Polarity will not affect the Z, but can

affect the quality and volume of the sound. If you are having

problems with any of these applications use Galaxy Audio's

CRICKET Polarity and Continuity Test Set to check the polarity of

your cables.

EXAMPLE 2:

As long as all of the speakers have the same impedance rating, the

equivalent impedance of the system is the rated impedance of one

speaker divided by the number of equivalent speakers.
