2 Ohm 4 Ohm Dual Voice Coil Wiring Diagram: Simplified Guide

What is a Dual Voice Coil Speaker?

A dual voice coil (DVC) speaker is a type of loudspeaker that uses two sets of voice coils to create sound. The two voice coils are usually connected in series or in parallel and wired to the same magnet and cone assembly. The term “dual voice coil” comes from the fact that the speaker can be wired for both series and parallel wiring configurations. This flexibility makes the dual voice coil speaker an ideal choice for many audio applications.

2 Ohm vs 4 Ohm Dual Voice Coil Speakers

The two main types of dual voice coil speakers are 2 ohm and 4 ohm versions. The number indicates the total impedance of the speaker when wired in parallel. A 2 ohm DVC speaker has two separate coils with a total of 2 ohms of resistance. A 4 ohm DVC speaker has two separate coils with a total of 4 ohms of resistance. The higher the impedance, the more current it requires to drive the speaker correctly.

Wiring a Dual Voice Coil Speaker to 2 Ohm

To wire a dual voice coil speaker to 2 ohm, the two voice coils must be wired in parallel. To do this, connect one positive terminal to one negative terminal on each voice coil. This will cause the two voice coils to act as one, resulting in a total impedance of 2 ohms.

Wiring a Dual Voice Coil Speaker to 4 Ohm

To wire a dual voice coil speaker to 4 ohm, the two voice coils must be wired in series. To do this, connect the positive terminal of one voice coil to the negative terminal of the other. This will cause the two voice coils to act as one, resulting in a total impedance of 4 ohms.

What Happens if You Wire a Dual Voice Coil Speaker to a Higher Impedance Than It Is Rated For?

If you wire a dual voice coil speaker to a higher impedance than it is rated for, the speaker may become damaged due to the increased current passing through it. This could result in distortion, reduced sound quality, and even permanent damage to the speaker. It is important to always ensure that the speaker is wired to the correct impedance before use.

What Happens if You Wire a Dual Voice Coil Speaker to a Lower Impedance Than It Is Rated For?

If you wire a dual voice coil speaker to a lower impedance than it is rated for, the speaker may not be able to produce enough power to reach the desired sound level. This could result in a weak and distorted sound. It is important to always ensure that the speaker is wired to the correct impedance before use.

Can You Mix Different Impedance Dual Voice Coil Speakers in a System?

Yes, you can mix different impedance dual voice coil speakers in a system. However, it is important to make sure that the total impedance of the system is equal to or greater than the amplifier’s minimum impedance rating. Otherwise the amplifier could be damaged due to excessive current passing through it.

What is the Difference Between Series and Parallel Wiring for Dual Voice Coil Speakers?

The difference between series and parallel wiring for dual voice coil speakers is the total impedance of the speaker. If the two voice coils are wired in series, the total impedance will be double the impedance of one of the coils. If the coils are wired in parallel, the total impedance will be equal to the impedance of one of the coils.

Advantages and Disadvantages of Wiring Dual Voice Coil Speakers in Series or Parallel

Wiring dual voice coil speakers in series or parallel each have their own advantages and disadvantages. Wiring in series will increase the total impedance of the speaker, which can help increase sound pressure levels in certain applications. However, it also decreases the sensitivity of the speaker, meaning it requires more power to reach the desired sound level. Wiring dual voice coil speakers in parallel will reduce the total impedance of the speaker, which can help increase the efficiency of the speaker. This can result in louder sound with less power. However, it also increases the amount of current passing through the speaker, which can lead to distortion and damage the speaker if not done correctly.
