Until you use few speakers it is easy to reach 4, 8, 16
Ω required by common amplifiers,
but when using more speakers
it is necessary to choose a type of mixed
series / parallel connection allowing us to
obtain the desired impedance.
Series / parallel mixed wiring
In this example the impedance of the 4 and 8Ω
speakers is added (being connected in series). Then
the 4 groups of speakers, connected in
parallel, halve their impedance to reach a total
impedance of 4Ω.
Here is an example:
4 speakers x
4
Ω
= 16
