HomeTheater System Subwoofer Maintenance and Care Tips

The subwoofer requires attention and care. Find out the basic maintenance and care tips to keep your subwoofer in top condition and performance.


Are you having problems with your subwoofer? Has it already started being faulty?

Subwoofer performance tends to deteriorate over time. It is not uncommon for electronics, even a subwoofer with excellent performance at an affordable price, to have problems as it gets old. However, there is a solution to keep electronic devices, such as subwoofers in their best condition. The key to keeping their performance is by correct maintenance and proper care.


Before you begin troubleshooting and tweaking the controls of your subwoofer, make sure it is powered off. Check if it is still plugged into the socket before starting the steps. The last thing you’ll want is to get electrocuted while fixing your subwoofer.

Tip #1: How to Keep it Clean

Dust build-up can cause problems on the subwoofer. Likewise, it is damaging to the exterior, especially when the subwoofer has a glossy finish.

One way to avoid dust build-up and other stubborn dirt stuck on the sound equipment, make sure to cover it after use. Covering the device helps prevent dirt collection; likewise, it preserves the design of the equipment.

If your subwoofer is laden with dirt, wipe it with a damp microfiber. Do not use strong chemicals or any harsh cleaning agent for it could damage the subwoofer. Wipe in straight and long strokes in the same direction. Never wipe the dust and dirt in a swirling motion for it can cause more damage on the subwoofer finish.

Tip #2: Troubleshoot 

Occasionally perform a maintenance check on your subwoofer. Look for problems and potential damages to the subwoofer. If you see one, immediately fix the problem to prevent it from getting worse.

A good way to learn to troubleshoot the device is by consulting its manufacturer manual. The device’s manual will provide you enough details on troubleshooting and ways to fix the problem. If not, you can always ask for assistance through online sources.

Tip #3: Check the Knobs and Switches

One of the most common problems in older amplifiers is that it tends to produce poor quality sounds. The root behind it is knobs and switches corrosion.

Knobs and switches tend to corrode internally over time. Corrosion increases noise and significantly drops sound output. The main reason behind knobs and switches corrosion is the low voltage on the amplifier.

It is possible to eliminate the noise if the knobs and switches are faulty. You can rotate the volume knobs and switches until there is no longer noise in the sound.

You can avoid this issue if you invest in amplifiers or home theater systems with no analog volume controls and switches in the low voltage signal path. If your current audio equipment has such a design, make sure to flip the switches occasionally to reduce the risk of corrosion.

If your subwoofer has serious damages, the best thing you can do is upgrade it with a better version that is more suitable for your home theater system.

Subwoofers have a fairly long lifespan with proper maintenance.

The key to making it last longer is smart care and attention.
