How Much Does It Cost To Fix A Blown Subwoofer?


A blown subwoofer can drastically affect your audio experience, creating distorted or no sound.

The cost to fix such a subwoofer depends on the extent of the damage, the specific model, and labour costs.

On an average, the basic cost of fixing a subwoofer can vary from $20 to more than $100.

However, it is crucial to consider the repair expenses compared to the overall value of a new subwoofer.

Keep in mind that not every blown subwoofer can be fixed through repairs.

Replacing the subwoofer entirely sometimes may be the more financially viable option.

Important Factors Influencing Repair Costs Of A Subwoofer

Type Of Damage

The cost of repairing a subwoofer can be influenced by the severity and type of damage it has incurred.

Issues such as a blown voice coil or a damaged cone can result in higher repair costs due to the need for component replacement or repair.

Brand and Model

The brand and model of the subwoofer can play a role in determining the repair costs.

Different brands and models may have unique components that are more specialised or expensive, which can affect the overall repair expenses.

Warranty Coverage

If the subwoofer is still within the warranty period, the warranty may cover the repair costs, significantly reducing or eliminating the expense.

Labour And Expertise

The complexity of the repair and the level of expertise required can impact the cost.

More intricate repairs may require additional time and effort, resulting in higher repair costs.

Additional parts

If the subwoofer requires replacement parts for repair, such as a new voice coil or cone, the cost of these components will be factored into the overall repair expense.

The cost of replacement parts can change based on the brand, model, and availability.

Maintenance Tips For Subwoofer To Prevent It From Blowing Out

Proper maintenance of your subwoofer is essential to ensure its optimal performance and longevity.

Regularly check the subwoofer for any signs of harm, such as cracks or dents in the box or the cone.

Avoid High Volume

One common cause of subwoofer damage is raising the volume too high.

Extended periods at maximum volume put extra stress on your subwoofer and can cause damage​​.

Give Your Subwoofer Breaks

Playing your subwoofer for extended periods without giving it a break can lead to overheating and eventual damage.

Like any other electronic device, your subwoofer needs rest and cooling down periods​.

Protect Against Power Surges

Power surges or fluctuations can cause damage as they put a large amount of stress on the amplifier and speaker components.

Use surge protectors to prevent power issues​.

Regular Cleaning

Regular cleaning of the subwoofer helps to prevent the build-up of dust and debris, which can cause the subwoofer’s voice coil to overheat, leading to failure​​.

Correct Installation

Incorrect installation can cause damage to your speakers or even blow out the subwoofer completely.

Make sure you install your subwoofer correctly​.

Adjust Your Crossover Frequency

For a multi-channel system with a powered subwoofer, set all your speakers to “small” in the receiver setup menu and set the crossover frequency slightly higher than the manufacturer’s recommendation.

This adjustment helps to ensure that your speakers do not attempt to play frequencies lower than they can handle, which could potentially damage them​​.

What Are Common Signs Of A Blown Subwoofer?

A blown subwoofer can exhibit several signs of damage.

Instead of producing sound, it may remain silent or emit distorted audio.

Additionally, you may notice a rattling noise coming from the subwoofer.

In some cases, the subwoofer cone might display visible signs of damage, such as cracks or holes.

This indicates a potential issue with the subwoofer’s internal components; repairing or replacing them may be necessary to restore proper functionality.

Is It Worth Repairing A Blown Subwoofer?

Deciding whether it’s worth repairing a blown subwoofer depends on a few factors.

Consider the repair cost compared to the cost of a new subwoofer.

If the repair cost is significantly lower, it may be worth fixing.

Also, evaluate the quality and age of the subwoofer.

If it’s a high-end model or has sentimental value, repair might be a better option.

However, if the subwoofer is outdated or low in quality, investing in a new one could provide better performance and longevity.

Can I Fix A Blown Subwoofer Myself?

Certain subwoofer problems can be resolved through DIY methods if you possess the appropriate tools and expertise.

Issues such as loose connections or minor driver adjustments can often be addressed at home.

Problems such as internal component failures or extensive damage are best left to professional technicians.

How Can I Prevent My Subwoofer From Blowing Out?

To keep your subwoofer working well, it is crucial to use it at a safe volume and not make the speaker work too hard.

If you turn up the volume too much it can get too hot and harm the inside parts of the subwoofer.

Furthermore, proper installation and ensuring that the subwoofer receives the correct amount of power are crucial for its longevity and functionality.

Can A Blown Subwoofer Produce Noise?

Yes, blown subwoofers can make noise, but the nature of the sound can significantly vary based on the extent and type of damage.

One of the most common audio issues you may notice is distortion.

A blown subwoofer may produce a distorted sound rather than the clear, deep bass it is designed to create.

The sound may be fuzzy, unclear, or crackling, which can differ from the usual smooth and deep output.

In cases where the damage is severe, the subwoofer might produce sound at a much-reduced volume or might not produce sound at all.

Thus, any noticeable audio quality or volume change could indicate a blown subwoofer.
