What To Do When Subwoofer Stopped Working?

A subwoofer is a kind of loudspeaker. It produces low-pitched frequencies otherwise known as bass, and sub-bass. It converts audio signals of the low pitch into the sounds the woofer can’t generate.

Maximum time subwoofer ranges stay in 20 Hertz to 2000 Hertz for consumer products. The ranges have in diameter from 8-21 inches. Many of the time, the Subwoofer Stopped Working. There are some significant reasons for stopping a Subwoofer. Now I am going to tell all the reasons below.

Subwoofer Stopped Working

Why Your Subwoofer Stopped Working

Why Your Subwoofer Stopped Working

Reason 1: Short Circuit

Short Circuit

The short-circuit is a common tool used for stopping any subwoofer. In emergency, it prevents the electrical signals’ passing into the Subwoofer. A short circuit also restrains the electrical, and current can’t go from reaching the Subwoofer.

The proper power which has in the wires can not be produced by the electromagnet for a short circuit, and the power won’t be able to drive the cone.

Reason 2: Driver Magnet Failure

Driver Magnet Failure

Instead of an electromagnet, both the Woofer and the Subwoofer has a permanent magnet. T the bottom of the Subwoofer near a coil, a magnet stay just to act as an electromagnet. All signals provide voltage and current through the electromagnet.

By attracting the permanent magnet the electromagnet drives the cone and produces better sound. So, if the permanent magnet break for any reason, then automatically, the electromagnetic pole will stop working, and it can not deliver to create any sound correctly.

Reason 3: Con Seal Failure

Con Seal Failure

Accurate frequency is very important in Woofer or subwoofer to produce good sound. That is why the air needs to move at Subwoofers in perfect frequency. The air shifts into the speaker’s cone back. Through the movement, it causes a pulling-pushing motion within the Subwoofer.

The cone is sealed with materials. So, if the cone gets damaged, then air cannot move properly in the Subwoofer. So if the cone seal gets damaged or breaks or falls in a lousy impact on it, then the Subwoofer will stop working.

Reason 4: Lack Of power

Reason 4 Lack Of power

If there is not providing the right power of frequency through the wires to the electromagnetic coil in Subwoofer then the permanent magnet will not work properly for lacking power.

Reason 5: The Effects Of Magnets On Speaker

Reason 5 The Effects Of Magnets On Speaker

Many students or children and also you may know about 2 magnet poles. When the two magnetic same poles stay near, they repulse each other, and when the opposite poles are staying near, they attract each other. There is a big cause for the attraction of the two magnets.

Their proximity causes an attraction force that results in the growth of a magnetic dipole. The term magnetic dipole refers to the absence of a magnetic pole situation on the same side of the magnet. In this way, the magnet works in the speaker.

Solutions For Your Subwoofer

Solutions For Your Subwoofer

There are some other reasons for stopping your Subwoofer. Before replacing or removing your bad Subwoofer you can try to fix the problems in your subwoofer. By following these steps, you can fix your Subwoofer;

Step 1: First, Check The Connection And Speaker Wires

Check The Connection And Speaker Wires

When a malfunction occurs, at first, you should examine every connections point of the amplifiers, speakers, and receivers for anomalies.

If you can see any connections cable or any wires become damaged, bring the new one and change the parts to recover your Subwoofer. You should carefully position the parts if you try to change them by yourself.

Step 2: Check Fuse, Outlets, And Power Cables

Check Fuse, Outlets, And Power Cables

Almost all the Subwoofer devices have a standby Led which indicates active power. If it will not work, then first check the securely plugged, which stays in a wall socket, and then check the power strip. If the plugs have any problem, then the wires cannot supply the power to the Subwoofer.

You should also check all the Switches. After reviewing these, if the Subwoofer still doesn’t give any proper response, give the plug into other Outlet.

Many Subwoofers are equipped with a fuse, and the fuse may require removal of the black plate sometimes and sometimes may not require.

You should check the fuse to see if it needs any replacement or it doesn’t need to replace. You can ask a manufacturer for any suggestions regarding the fuse if necessary.

Step 3: Check System And Menu Settings

Step 3 Check System And Menu Settings

After checking all the cables and wires, if can’t find any wrong in these, If all things look good, you should revisit the menu settings on your amplifier or receiver. It could happen that someone else had changed the settings unintentionally in your absence. So that check the menu settings.

Step 4: Verify Connections, Set The Volume, And Turn On The Subwoofer

Verify Connections, Set The Volume, And Turn On The Subwoofer

Re-check all the settings and connections. After verifying all, turn on the Subwoofer. Check the volume levels on the Subwoofer prior to sending audio inputs to an amplifier or a receiver. At first, keep the volume low and then increase it gradually. Deter the volumes when the Subwoofer works without issues.


After taking all steps, doing all things if your Subwoofer Stopped Working, If the power does not on or if the power on, but the Subwoofer programs fail to play any items properly, there is no other option without doing it replace.
