Introduction to Subwoofers
Subwoofers play an essential role in achieving a complete audio experience, whether in a home theater system or a car audio setup. They are designed to reproduce low-frequency sounds, adding depth and richness to music, movies, and other audio content. However, not all subwoofers are created equal. Among the different types available in the market, the dual voice coil subwoofer stands out due to its unique design and versatile functionalities.
In this article, we will explore what a dual voice coil subwoofer is, how it works, and why you might consider one for your audio system. We’ll also delve into the various benefits, installation tips, and applications, providing you with a comprehensive understanding of this powerful audio component.
What is a Dual Voice Coil Subwoofer?
At its core, a dual voice coil (DVC) subwoofer is a speaker that features two separate voice coils instead of one. These coils are used to create magnetic fields that move the subwoofer’s cone, generating sound waves. The dual voice coil design offers unique advantages in terms of impedance configurations, power management, and overall sound performance.
Components of a Dual Voice Coil Subwoofer
To better understand how a dual voice coil subwoofer works, it’s helpful to break down its components:
- Voice Coils: The heart of the speaker, they convert electrical energy into mechanical energy to generate sound.
- Magnet: Provides the magnetic field necessary for the voice coils to operate effectively.
- Cone: The part that moves to create sound waves, typically made from materials such as polypropylene or fiberglass.
- Suspension System: Maintains the alignment of the cone, allowing it to move freely and accurately.
How Does a Dual Voice Coil Subwoofer Work?
The operation of a dual voice coil subwoofer can be broken down into several steps:
Electrical Signal Input
When an audio signal is fed into the subwoofer, it travels to both voice coils.
Magnetism and Movement
The electrical signal creates an electromagnetic field in both voice coils. This field interacts with the permanent magnet, causing the coil and cone to move back and forth.
Sound Wave Production
As the cone moves, it displaces air, producing sound waves that correspond to the audio signal. The movement varies according to the frequency and amplitude of the input signal, resulting in deep, rich bass sounds.
Advantages of Dual Voice Coil Subwoofers
The dual voice coil design offers several significant advantages over single voice coil counterparts:
Flexibility in Wiring Configurations
One of the most notable benefits of dual voice coil subwoofers is their flexibility in wiring. You have the option to wire the coils in series or parallel, allowing you to adjust the total impedance of the subwoofer to match your amplifier’s output. This flexibility can lead to enhanced performance and compatibility with various audio systems.
Increased Power Handling
With two voice coils working in tandem, a DVC subwoofer can handle more power than a traditional single voice coil subwoofer. This increased power capacity translates into better sound quality, improved dynamics, and enhanced overall performance.
Better Sound Quality
The ability to distribute the electrical signal across two coils can lead to more efficient movements of the cone, resulting in cleaner audio with reduced distortion. You’ll benefit from more precise bass response, making your audio listening experience much more enjoyable.
Power Handling and Impedance Explained
Understanding power handling and impedance is crucial for anyone considering a dual voice coil subwoofer.
Impedance Levels
DVC subwoofers commonly come in configurations of 2-ohm, 4-ohm, or 8-ohm impedance. When wiring in series, you add the impedance together, while wiring in parallel allows you to divide the total impedance by the number of coils.
Series vs. Parallel Wiring
| Wiring Configuration | Total Impedance (Ohms) | Load on Amplifier |
|---|---|---|
| Series | Coil 1 Impedance + Coil 2 Impedance | Higher load |
| Parallel | (Coil 1 Impedance * Coil 2 Impedance) / (Coil 1 Impedance + Coil 2 Impedance) | Lower load |
This versatile wiring option opens up many possibilities for customizing your audio setup to fit your specific needs.
Considerations for Choosing a Dual Voice Coil Subwoofer
When selecting a dual voice coil subwoofer, several factors come into play to ensure you make the right choice for your audio system:
Power Requirements
Ensure that your amplifier is compatible with the subwoofer’s impedance and power rating. Check the RMS (Root Mean Square) power rating of the subwoofer to avoid potential damage to your audio system.
Size and Enclosure Type
The size of the subwoofer will determine how deep and loud the bass can go. Larger subwoofers can produce lower frequencies but may require larger enclosures. Decide whether you need a sealed or ported enclosure based on your desired sound profile.
Installation Tips for Dual Voice Coil Subwoofers
Installing a dual voice coil subwoofer can be complex, but with careful planning, you can achieve great results.
Mounting the Subwoofer
Ensure the subwoofer is mounted securely in a properly sized enclosure. If you’re building your own box, ensure it’s well-sealed to enhance sound clarity.
Wiring Considerations
Pay close attention to the wiring configuration, making sure you connect both voice coils correctly to maintain balanced performance. Always double-check the amplifier settings to match the impedance of your setup.
Common Applications of Dual Voice Coil Subwoofers
Dual voice coil subwoofers are versatile and can be used in various settings, including:

What is a dual voice coil subwoofer?
A dual voice coil subwoofer is a type of subwoofer that features two separate voice coils within a single speaker. Each voice coil is essentially an electromagnet that interacts with the speaker’s magnetic field to produce sound. This design allows for increased flexibility in wiring configurations, enabling users to either connect multiple subwoofers or configure them for different impedance levels.
The benefit of the dual voice coil setup is that it can enhance the performance of the subwoofer in various audio systems. It allows for parallel or series wiring, which effectively increases the speaker’s efficiency and power handling capabilities. This flexibility is invaluable for customizing an audio setup to match a vehicle’s sound system or a home theater.
How do I wire a dual voice coil subwoofer?
Wiring a dual voice coil subwoofer can be done in two primary configurations: series and parallel. In a series configuration, both voice coils are connected end-to-end, which effectively doubles the impedance. For instance, connecting two 4-ohm coils in series results in an 8-ohm load. This wiring method is often used to match the subwoofer’s impedance with the amplifier’s output.
In contrast, a parallel connection involves wiring both voice coils directly to the amplifier terminals, reducing the overall impedance. For example, two 4-ohm coils wired in parallel will create a 2-ohm load. When wiring, it’s essential to carefully follow your amplifier’s capabilities to ensure optimal performance and prevent damage.
What are the advantages of dual voice coil subwoofers?
The key advantages of dual voice coil subwoofers are versatility and improved performance.
