In this comprehensive article, we will delve deep into the mechanics of subwoofers, explore the advantages and disadvantages of dual voice coils, and uncover whether they genuinely offer more punch than single voice coil designs.
Understanding Subwoofer Voice Coils
Before we explore the benefits of dual voice coils, it’s essential to understand what a voice coil is and how it affects subwoofer performance.
What is a Voice Coil?
A voice coil is an essential component of a subwoofer or speaker. When an electric current passes through the wire coil, it generates a magnetic field, which interacts with a permanent magnet in the speaker. This interaction causes the cone to move, producing sound waves. There are two primary types of voice coils: single voice coils (SVC) and dual voice coils (DVC).
Single Voice Coils vs. Dual Voice Coils
-
Single Voice Coils (SVC): SVC subwoofers have one voice coil. They come in various impedances (typically 2, 4, or 8 ohms) and are relatively simpler to wire. However, the design limits flexibility in terms of powering and impedance matching to amplifiers.
-
Dual Voice Coils (DVC): DVC subwoofers feature two voice coils, allowing for more complex wiring configurations. They commonly come in setups like 2-ohm/4-ohm or 4-ohm/4-ohm. This dual configuration facilitates wiring in series or parallel, enhancing versatility and power handling.
The Mechanics of Bass Production
