Polk Signa S2 or S1 Subwoofer Not Working, 8 Fixes

I will show you how to fix the problem with your subwoofer so you can enjoy your music again. I have tried fixing this issue many times and I am glad to share my experience with you.

A subwoofer is an amplifier that is used to boost the volume of your music. These amplifiers are usually installed in a car, but you can install one in your home too. However, as with any electronic device, there are problems that can occur.

The S2 subwoofer has two types of cone drivers. The first type is known as a ‘cone’ driver, which is similar to the woofer in a typical subwoofer. The second type is a ‘plate’ driver, which is similar to the woofer in a typical mid-range speaker.

Secure the Connections

If the subwoofer has an internal amplifier, make sure that the power supply cord is connected to the power switch. If the subwoofer has an external amplifier, the power supply should be plugged into the amplifier’s input jack. If the power supply is not plugged into the power switch or the amplifier’s input jack, the amplifier won’t be able to provide power to the subwoofer.

Most homes have at least one wall power outlet, but sometimes the voltage may be low. If the outlet is working properly, you should have no problems. However, if the outlet is not working, check the fuse box or contact a professional electrician.

The way that an amplifier is wired and how it is powered can have a big impact on the quality of sound and the overall performance. If you notice any strange noises or problems with the amplifier, it is a good idea to contact the manufacturer.

Examine the Cables

 If your subwoofer is having a problem with its power cord, you need to check the power cord first. It could be damaged or faulty. Try changing the power cord.

I have a friend who purchased an AC adapter that did not work well. He tried everything to get it to work, but nothing worked. After about a year, he finally replaced it with another one. If you’re having problems with your AC adapter or power cord, you should try to change them out to see if that helps.

 Check the Settings

The subwoofer should be connected to the receiver using a speaker wire. You may need to use a separate amp for the subwoofer if your receiver does not have a built-in amp. Make sure the receiver’s volume control is set to the maximum before connecting the subwoofer.

You might not know this, but the subwoofer is one of the most important pieces of equipment you can have in your home or office. It is the speaker that is responsible for creating the bass in your music, so it’s important that you get the right subwoofer for the job. 

Use A Grounding Plug

Ground loops are caused by electrical noise entering the receiver through the speaker terminals and being reflected back to the amplifier. To prevent this, make sure you connect a grounding plug between the speaker and the amplifier.

Sometimes when we have a problem, we don’t know where to start, and the first step is often to try and fix the symptom instead of the root cause. But the TV is only a symptom. You may be able to fix the TV, but if the source of the problem is your wiring, then you’ll have to deal with that.

Power Cycle the Subwoofer

You can try this on your computer, too. Just unplug the power supply for a few seconds and plug it back in again. This will also work on most laptops.

Reset Polk Signa Soundbar

If your subwoofer is not playing, the most likely culprit is a bad connection between the soundbar and subwoofer. A quick test can be done by disconnecting the subwoofer from the soundbar and reconnecting after 30 seconds. This will clear the soundbar’s memory of any settings that may have been stored.

Resync Polk Soundbar and Subwoofer

1.After you sync the soundbar and subwoofer, you can use the following steps to sync them again:

2. Press the “Menu” button on the remote control and select “Sound Settings”.

3. Select “Subwoofer”, and then press “OK”.

4. Press the “Menu” button on the remote control and select “Speaker Settings”.

5. Select “Soundbar”, and then press “OK”.

Test the Source Device

If the cable is worn out or damaged, it can cause issues with sound quality. You should always test the source device first before connecting the subwoofer. This way, you can check whether the speaker is working properly.

If the audio and video systems are not working, then you can test the connections by using an inexpensive audio test tool, such as the one I use.

When you’re listening to music, you may find yourself reaching for the volume button on your remote control. But there’s a good reason why the volume is so low. Music is supposed to be loud! If you turn up the volume too high, you risk damaging your ears.
