The Home theater subwoofer does not work in excessive heat and equipment failure conditions. The broken connections and inappropriate settings lead to these problems. Consider technical help to resolve the subwoofer problems. 

Why is My Home Theater Subwoofer Not Working? In general, the home theater subwoofer does not work due to broken cone seals, short circuits, and faulty knobs. It occurs with insufficient electric power, fault of electromagnetic field, damaged plugs, and broken wires. In addition, the excessive heat of the home theater, broken fuse, and failure of electric ports cause subwoofer failure. 

Leaving the damages of the sound devices without any control can generate significant issues. However, a few of the problems are irreparable, and you have to replace the subwoofer. 

Why is My Home Theater Subwoofer Not Working?

I have explained the reasons and their solutions to avoid these issues. 

Maintenance of your sound system is an essential thing for their standard performance. 

Fluctuation of electric current

The subwoofers of a home theater are electric appliances, and they require a constant electric supply for their standard function. So once you turn them on, then you have to maintain the electric passage throughout.

The fluctuation of electric current occurs in the source of this power. Also, multiple cables offer the signals to the subwoofers for the audio response.

Inadequate current supply leads to a lack of audio signals. So it stops working from this point, and you cannot hear any more audio from them.

The electric coils of the subwoofer also go through the short circuits. However, so few of them exceed that level that the device fails to work accurately. 

Check the central source of the electric supply and adjust the connectors. The tightening of these tools helps in the prevention of short circuits. Also, replace the damaged coils for the constant and error-free flow of electric current. 

Broken inner seals of home theater subwoofers

The subwoofers of a home theater comprise multiple tools that can circulate air. The production of sound is convenient due to this forward and backward movement of the air. 

The subwoofer cone sections are one of the dominant structures to perform these activities. These tools have sealing material around them for excellent protection. In few cases, the seal around the cone declines or breaks due to old age and other issues. 

The resistance ability of the device decreases due to seal damages, and it fails to work. 

The air tools can push and drag air, but the results are not advantageous. They become inappropriate for the production of sufficient audio signals.

Check the broken seal and replace it instantly.

Faulty magnetic field

There is a magnetic field inside the sound systems like a subwoofer for the production and stability of constant audio signals. The electric power sources of these sound devices send electric signals to the magnet. 

It is available at the lower side of the subwoofer cone section. The electric power reaches the magnetic first, and there is a development of electromagnetic fields. 

The resistance of electric signals by this magnet results in the production of sound. Therefore, it depends on the correct efficiency of this structure. 

In few circumstances, the magnet can break, affects the cone and other parts of the sound device. The subwoofer lacks the efficiency to work.

Approach the cone and magnet of the subwoofer, and then observe the condition. 

Alter the broken magnet with a new device for excellent performance.

No electric power

These electric instruments require continuous electric power for their performance. The electric sources take part in these activities, and the overall setup works.

The insufficient electric power supply to the inner coil and the magnetic field of the subwoofer leads to multiple issues like lack of performance. 

The audio signals diminish, and initially, they get blur. The supply of power is irregular, and it also damages the inner parts of the structures.

The overall setup becomes vulnerable that is right for a sound device. The maintenance of an adequate power supply is the only solution for these problems.

Approve the electric power sources of your subwoofer and identify the issues. Then, insert the plugs appropriately, and supply constant power to your system. 

Change the center of electric supply in case of severe issues.

Faulty electric wiring

The electric wiring of a home theater is one of the essential factors for its continuous and excellent performance. 

The broken electric wires or tearing of these structures from various parts leads to multiple problems.

The sound devices depend on these electric current sources, and in case of problems, failure occurs.

Few of them do not connect firmly, and loosening can lead to a variation of current. 

Sometimes, they are not plugins inside the sockets with their front tools. All of these factors make the structure vulnerable, and they do not work appropriately. 

Identify the electric connections and check the overall condition of the electric wires. Tighten them if they lose from the connecting points. 

Replace the electric wires with new structures and then connect them with the sound device. 

Insufficient plugging

The problem of insufficient plugging originates due to human negligence. The home theater sound devices have a specific electric power cable with a switch. 

You have to attach the switch inside the socket for the excellent work efficiency of your sound tool. 

Few people do not connect the switch appropriately inside the electric panel, and it occurs due to haste. 

When there is no provision of electric power to the system; as a result, they cannot perform, and the audio signals are not available. 

The problem is resolvable with the preventive measures. There is no need to check the tricky parts of the subwoofer in the initial stages.

Improper receiver connection with subwoofers

The receiver of the sound system offers audio signals with its settings. It also handles the fluctuation of information inside the device. 

The subwoofers connect with the receiver through the HDMI ports. In few cases, the ports are not matching, but still, people insert them.

It harms the inner settings of the system. It gets vulnerable when the options show signs of big rather than small. 

It is an inappropriate connection between these electric appliances. The problem leads to the sound tools, and they do not generate the audio.

Inspect the overall design of the receiver and check connections. Then, observe the settings and change them according to standard rules. 

No attachment of electric power cord

The electric power cord is the central electric cable that combines the electric sources with these tools. 

These are long and sufficient enough to produce adequate sound signals and balance the home theater subwoofers. Many people use the extension structures due to the inappropriate length of this cord. 

They forget to attach the power cord to the electric source. The fixing is loose, and it also leads to other errors. As a result, the overall system stops working, and you hear no sound.

Check the attachment of the electric cord of your system. In case of loosening, fix it back to the electric source. If you find improper cord performance, then replace it with professional expertise. 

Mixed settings of home theater system

The settings of the subwoofers depend on the built-in settings, and few users alter them accordingly. 

It happens when there is a low to a high audio frequency of sounds.

There is a general rule that the front subwoofers have the signals in the begging and, then it reaches back subwoofers. So it is also a crossover of the sounds.

The mixing of the signals can produce distortion, and the sound tools can tolerate it to some extent.

In some situations, the problems are considerable than standard errors.

In this way, the sound device stops working, and there is no production of audio signals. As a result, you cannot hear sufficient volumes due to a lack of performance.

Avoid the mixing of signals by keeping the settings in a manner able order. 

Insufficient compatibility with ports

The ports of the subwoofers are connecting points for the electric wires, and they can absorb electric current. However, these ports can break due to excessive and inaccurate usage. 

The old age of these connecting joints can also lead to damages. This is because the electric wires cannot connect to these particular points. 

The system fails to work due to the non-connecting abilities of the electric wires with the broken ports. There is no interference of electric connection in such situations because the device itself does not work. 

Observe the ports when you establish a setup of subwoofers. Then, take professional support to replace these ports with a new and efficient connecting point.

Failure of the audio section

The audio section of the home theaters depends on the appropriate electric wires and their fitting. However, the damage is due to excessive inner heating. 

The connection loses, and there is no electric supply. These damages occur inside the device that directly impacts the sound production. 

The heat can burn the electric passage internally, and no external repairing can stabilize the setup. It can also melt the insulation of these wires that can make the system stop working.

Repairing the device and its inner wiring is necessary to resolve these issues. Prevent it from overheating and adjust the setup in a moderate environment. 

Change the electric wiring with a new and efficient setup. The audio signals become sufficient after these changes. 

Broken Sound knob 

The sound knob of the home theater subwoofers is one of the significant devices. It handles the volume of this sound system according to the user’s requirement.

The broken knobs cannot rotate for the production of high or low volume conditions. It can occur due to external and internal damages to this tool. 

It sticks in one position, and you cannot hear any audio. The repair and inspection of other parts cannot resolve these issues. 

Change it with a new knob with expert skills. Hire a professional for the alteration of these volume controllers. 

Broken subwoofer fuse

A fuse of the subwoofer is the protection tool that can maintain electrical changes. It is resistant to electric surges and discards them from the system.

They have blowing ability that can handle the changes of power in the home theater sound setups.

The fuses may break or be blown out due to high voltage conditions that are more than the handling ability of this tool. 

Maintain the electric flow to avoid surges inside these home theaters. For example, change the subwoofer fuse with a new device and then increase volume.
