Coil Configurations
Understanding single vs dual voice coil subwoofers and how to choose between them.
On this page
Neither dual voice coil (DVC) nor single voice coil (SVC) configuration is inherently superior. The choice depends on your specific amplifier and wiring needs.
Key Difference
The main distinction lies in impedance flexibility. The difference in the coil configuration helps determine the impedance (or resistance) an amplifier will see when the subwoofers are wired to the amplifier.
Dual Voice Coil (DVC) Advantages
Dual voice coil subwoofers are currently more prevalent in the market because they provide greater options on the number of subwoofers to be wired together to achieve desired stable ohm loads on amplifiers. This flexibility makes them attractive for complex installations.
Single Voice Coil (SVC)
While less common today, single voice coil subwoofers remain viable depending on your amplifier's capabilities and your installation requirements.
Dual 4-Ohm vs. Dual 2-Ohm
Similarly, no inherent superiority exists between dual 4-ohm and dual 2-ohm configurations. Your choice should align with your amplifier's specifications and the total number of subwoofers you plan to connect simultaneously.
Recommendation
Evaluate your amplifier's capabilities and desired subwoofer quantity before selecting a coil configuration.
