Parallel vs Series Speakers: Which One Is Better?
Parallel vs Series Speakers: Which One Is Better?
Speakers are an important component in sound systems and the way they are connected can greatly affect the final sound output. In audio systems, speakers can be connected either in parallel or in series. Parallel connection involves connecting multiple speakers to a single point, while series connection involves connecting speakers one after the other. Both configurations have their own advantages and disadvantages and the choice between them depends on the specific application and the desired sound output. In this article, we will explore the differences between parallel and series speaker connections and help you understand the pros and cons of each.
What Are Parallel speakers?
Parallel speakers refer to a configuration of multiple speakers connected to an audio system in such a way that the positive terminal of one speaker is connected to the positive terminal of another speaker, and the negative terminal of one speaker is connected to the negative terminal of another speaker. In this way, the speakers are “parallel” to each other, hence the name.
In a parallel speaker connection, the impedance of the system is divided among the connected speakers. The more speakers that are connected in parallel, the lower the overall impedance of the system. This configuration is simple to set up, and it does not require matching speaker impedances. However, it can result in unequal power distribution between speakers if they have mismatched impedances, potentially damaging the speakers.
What Are Series Speakers?
Series speakers refer to a configuration of multiple speakers connected to an audio system in such a way that the positive terminal of one speaker is connected to the negative terminal of another speaker. This creates a circuit, with the speakers “in series” with each other, hence the name.
In a series speaker connection, the overall impedance of the system is equal to the sum of the impedances of the connected speakers. This configuration requires matching speaker impedances, as unequal impedances will result in unequal current flow and potentially damaging one or more speakers. Series speaker connections can handle higher voltages compared to parallel connections, and they can provide improved protection for the amplifier. However, the power handling capabilities of the system may be reduced compared to parallel connections, and the wiring can be more complex.

Disadvantages of Series Connections
Here are the disadvantages of series speaker connections in small bullet points:
- Matching speaker impedances can be challenging
- Reduced power handling capabilities compared to parallel connections
- Unequal current flow between speakers if impedances are not matched, leading to unequal volume levels and potentially damaging the speakers
- May require additional components to match speaker impedances, such as transformers or resistors
- May result in increased overall system complexity and cost compared to parallel connections.
Parallel or Series Speakers – Which is better?
Parallel connections offer greater power handling capabilities, improved efficiency, and better sound quality. However, they also have the potential for increased distortion and decreased overall system impedance.
On the other hand, series connections allow for greater voltage handling capabilities and increased overall system impedance. However, they also require matching speaker impedances and may result in reduced power handling.
When deciding between parallel and series speaker connections, it is important to consider the specific requirements of the audio system, such as power handling, efficiency, and overall system impedance. Consulting with a professional or using technical resources can help ensure that the right decision is made for the desired sound output.
