Single or Dual Voice Coil Subwoofer, which one is better? Many people question about the advantages and disadvantages of single and dual voice coils while purchasing subwoofers. To properly understand the difference between these two types of subwoofers, a better understanding of an amplifier is required.
Comparison chart for Single Voice Coil Subwoofer vs Dual Voice Coil Subwoofer
Whenever the Single and Dual Voice Coil Subwoofers are compared, we can not start the discussion without mentioning the wiring advantage of DVC over SVC. There is only one possible combination for a single voice coil subwoofer to be wired with an amplifier. Whereas, dual voice coil subwoofer offers two possible combinations of wiring for a single DVC.

As the number of subwoofers increases, these possible combinations also increase for both types of subwoofers. However, DVC always has an advantage over SVC for offering more possible combinations.
Application in Cars
In cars, the typical load resistance for the audio signal is between 1 and 4 ohms. Hence, this low impedance combined with the amplified signal voltage results in a relatively large amount of currents that flow through the voice coil of the speaker.
This flow of current gives rise to magnetic fields. Hence, the principle of electromagnetism is utilized in the voice coils in the presence of a stationary magnet on the speaker.
