In a series-parallel connection, as the name suggests, both series and parallel connections are used, typically to adapt speakers in a sound system project.
Example:
We will use 4 speakers of 2 Ohms each to be connected to a 2-ohm amplifier output. To better understand how the impedance combination works in this case, we can use a simple calculation:
2 Ohms + 2 speakers = 4 Ohms.
So, we divide the result 4 (Ohms) by 2 (speakers), resulting in a final impedance of 2 Ohms.
Below is an example of how these speakers would be connected in practice:
A mixed connection can also be made with dual voice coil speakers. In the example below, we have 2 dual 4-ohm voice coil speakers, which will be connected to a 4-ohm amplifier.
This way, we conclude that with a series-parallel connection, we can easily adapt the arrangement of speakers in the most suitable way for the sound system!
