A dual voice coil subwoofer is a subwoofer that has two separate voice coils instead of one. Each voice coil has its own speaker terminals, giving installers more flexibility when wiring the subwoofer to an amplifier.
The main benefit of a dual voice coil subwoofer is wiring flexibility. Depending on the subwoofer’s impedance and amplifier compatibility, the voice coils may be wired in different configurations to achieve a suitable final impedance load. This can help match the subwoofer correctly to the amplifier for better power delivery and safer operation.
A dual voice coil design does not automatically mean the subwoofer is louder or better than a single voice coil model. The final performance depends on the subwoofer design, amplifier power, enclosure type, impedance, tuning and installation quality.
Correct wiring is very important. If a dual voice coil subwoofer is wired incorrectly, the amplifier may see the wrong impedance load, which can lead to poor performance, distortion, overheating or amplifier protection issues.
For the safest and best-performing setup, speak with your nearest Focal Authorised Australian Dealer. A professional dealer can confirm the correct wiring configuration, amplifier match and enclosure setup for your Focal subwoofer system.
