When it comes to subwoofers, one of the most common questions that arises is whether you need to use both voice coils. The answer to this question is not a simple yes or no, as it depends on various factors, including the type of subwoofer, the amplifier, and the desired sound quality. In this article, we will delve into the world of subwoofer voice coils and explore the pros and cons of using one or both coils.
Understanding Subwoofer Voice Coils
A subwoofer voice coil is a crucial component of a subwoofer speaker. It is responsible for converting the electrical energy from the amplifier into mechanical energy, which then produces sound waves. A voice coil consists of a wire coil suspended in a magnetic field. When an electrical current flows through the coil, it interacts with the magnetic field, causing the coil to move back and forth. This movement creates sound waves that we perceive as sound.
Most subwoofers have two voice coils, which are usually connected in parallel or series. The two coils are typically identical and are designed to work together to produce sound. However, it is possible to use only one coil, and this is where things get interesting.

Using Only One Voice Coil
So, what happens if you use only one voice coil? Here are a few things to consider:
- Reduced Power Handling: When only one coil is used, the subwoofer can handle less power from the amplifier. This means that you may need to reduce the volume to avoid damaging the subwoofer.
- Lower Sound Quality: Using only one coil can result in lower sound quality, as the single coil may not be able to produce the same level of detail and accuracy as two coils.
- Reduced Efficiency: When only one coil is used, the subwoofer is less efficient, meaning that it may require more power to produce the same level of sound.
When To Use Only One Voice Coil
There are a few situations where using only one voice coil may be acceptable:
- Low-Power Applications: If you are using a low-power amplifier, you may not need to use both coils. In this case, using only one coil can be sufficient.
- Small Subwoofers: Small subwoofers may only have a single coil, and in this case, using only one coil is the only option.
- Experimental Applications: If you are experimenting with different subwoofer configurations, you may want to try using only one coil to see how it affects the sound quality.
Conclusion
In conclusion, whether you need to use both voice coils on a subwoofer depends on various factors, including the type of subwoofer, the amplifier, and the desired sound quality. While using both coils has its advantages, there are also situations where using only one coil may be acceptable. Ultimately, the decision to use one or both coils should be based on your specific needs and preferences.
By understanding the pros and cons of using one or both voice coils, you can make an informed decision and get the best possible sound quality from your subwoofer. Whether you are a seasoned audiophile or just starting to explore the world of subwoofers, this knowledge can help you unlock the secrets of subwoofer voice coils and take your sound to the next level.
What Is The Purpose Of A Subwoofer Voice Coil?
The primary function of a subwoofer voice coil is to convert electrical energy into mechanical energy, which then produces sound waves. This is achieved through the interaction between the voice coil and the magnetic field within the subwoofer. When an electrical current flows through the voice coil, it generates a magnetic field that interacts with the permanent magnet, causing the coil to move back and forth. This movement drives the subwoofer’s diaphragm, producing low-frequency sound waves.
In a typical subwoofer design, the voice coil plays a crucial role in determining the overall performance and sound quality of the system. The voice coil’s design, including its diameter, length, and material, affects the subwoofer’s frequency response, power handling, and efficiency. As such, selecting the right voice coil for a subwoofer is essential to achieve optimal performance and sound quality.
What Are The Benefits Of Using Dual Voice Coils In A Subwoofer?
Using dual voice coils in a subwoofer offers several benefits, including increased power handling, improved thermal management, and enhanced sound quality. With two voice coils, the subwoofer can handle more power, as the electrical current is divided between the two coils, reducing the risk of overheating and damage. Additionally, dual voice coils allow for more flexible wiring configurations, enabling users to customize the subwoofer’s impedance and power handling to suit their specific needs.
Another advantage of dual voice coils is improved thermal management. By dividing the electrical current between two coils, the heat generated by the subwoofer is dissipated more efficiently, reducing the risk of overheating and prolonging the lifespan of the subwoofer. Furthermore, dual voice coils can provide a more detailed and nuanced sound, as the two coils can be configured to operate in different modes, such as parallel or series, to optimize the subwoofer’s frequency response and sound quality.
Can I Use A Single Voice Coil In A Subwoofer Designed For Dual Voice Coils?
While it is technically possible to use a single voice coil in a subwoofer designed for dual voice coils, it is not recommended. Using a single voice coil in a dual-voice-coil subwoofer can lead to reduced power handling, decreased sound quality, and potentially even damage to the subwoofer. The subwoofer’s design and electrical configuration are optimized for dual voice coils, and using a single coil can disrupt this balance.
If you only have a single voice coil available, it is recommended to use a subwoofer designed specifically for single voice coils. This will ensure that the subwoofer operates within its intended specifications and provides optimal performance and sound quality. Using a single voice coil in a dual-voice-coil subwoofer can also void the manufacturer’s warranty and potentially cause damage to the subwoofer.
How Do I Wire A Dual-voice-coil Subwoofer?
Wiring a dual-voice-coil subwoofer requires careful attention to the subwoofer’s electrical configuration and the desired impedance and power handling. The most common wiring configurations for dual-voice-coil subwoofers are parallel and series. In a parallel configuration, the two voice coils are connected in parallel, resulting in a lower impedance and increased power handling. In a series configuration, the two voice coils are connected in series, resulting in a higher impedance and reduced power handling.
When wiring a dual-voice-coil subwoofer, it is essential to follow the manufacturer’s instructions and recommendations. The subwoofer’s manual should provide detailed wiring diagrams and instructions for the desired configuration. It is also crucial to ensure that the wiring is secure, and the connections are tight to prevent electrical noise and damage to the subwoofer.
