Short Circuit in Subwoofer: What are the Causes?
Surprisingly, your subwoofer suddenly short-circuited. What could be the cause of this? Is there are a remedy to this problem? And how can you prevent subwoofers from short-circuit? Learn more about it here.
Subwoofers vastly enhance the sonic performance of a home theater system. If you compare such a unit with a subwoofer versus one with none, you will immediately notice the difference. Home theater systems with a subwoofer have more impact and depth. The sound it produces reverberates to your chest, making you feel the music or movie you’re watching. Meanwhile, a surround sound unit without a subwoofer seems groundless. It feels like there’s a hole and gap in the sounds, which makes the music and sound effects less fun.
The reason behind this is the ability of the subwoofer to pick up very low sound frequencies, known as bass. Its main function is to produce clear bass, which fills the void in the sound.
Usage, tear, and wear are the common root behind poor subwoofer performance similar to other electronic equipment. But aside from these reasons, another cause why the subwoofer fails is the short circuit.
What is Short Circuit in Subwoofers?
A short circuit is one of the common reasons for speaker failure. It may occur in different parts of the speaker; mainly on the wires, terminals, and coil.
The wires serve as the path of signals towards the subwoofer. A short circuit on the wires prevents the signal from reaching the subwoofer. As a result, the unit fails to produce and create sounds.
On the other hand, a short circuit on the terminal of the subwoofer blocks the electrical current and signal from reaching the unit, which also negatively affects the performance of the unit.
Experts say that a short circuit in the terminal of a subwoofer is the most lethal to the equipment. It completely stops the electrical current, preventing the subwoofer from turning on.
A short circuit on the coil significantly reduces the power produces by the electromagnets. When it happens, the coil fails to produce enough power to drive the cone from performing its function. And the result is subwoofer failure.
What Causes Short Circuit in Subwoofers?
Lack of power – it is the primary and only cause of short circuits in subwoofers as well as other speakers. If there is less amperage that reaches the electromagnetic coil, there will be less power and strength, which causes failed interaction between the electromagnetic field and the permanent magnet.
When there is less power, the signal fails the reach the subwoofer, thereby leading to non-performance.
How to Prevent Short Circuit?
The best way to circumvent a short circuit is to ensure enough power goes to the subwoofer. Make sure to know the wattage and power requirement of the unit you bought. Also, check out subwoofers protected against short-circuiting here at Home Cinema Effect. This unique feature in some subwoofers preserves the lifespan of the unit and guarantees fewer chances of short-circuiting.
Therefore, you have to pay more attention to your subwoofer. Get to know your unit and learn more about its basics to get the most out of it.
