Parallel wiring involves connecting the two coils of a DVC subwoofer in parallel, which decreases the impedance of the subwoofer. This can be beneficial for low-power audio systems, as it allows for more sound to be produced per watt.
Conclusion
When it comes to choosing between an SVC and DVC subwoofer, there are several factors to consider. SVC subwoofers are often less expensive and easier to install, but may have limited flexibility and lower power handling capabilities. DVC subwoofers offer more flexibility and higher power handling capabilities, but may be more expensive and more difficult to install. Ultimately, the right choice for you will depend on your specific audio needs and preferences.
By considering the advantages and disadvantages of each type of subwoofer, as well as your specific needs and budget, you can make an informed decision and choose the right subwoofer for your audio system.
