Low Impedance Speakers (cont)
In certain cases, it may be necessary to use a
combination of series and parallel wiring to achieve
the desired impedance.
The adjacent illustration demonstrates a common
method of connecting four 8
Ω
speakers, and
maintaining a combined 8
Ω
load.
In this case, speakers are separated into pairs,
connected in series. Each series pair yields 16
Ω
.
Since both sets are then connected in parallel, the net
impedance is 8
Ω
.
In this second example of a
combination of series and parallel
wiring, eight 8
Ω
speakers are
combined to create a combined 4
Ω
load.
In this case, speakers are separated
into pairs, connected in series. Each
of the four series pair yields 16
Ω
.
Since the four pairs are then
connected in parallel, the net
impedance is 4
Ω
.
