But still, there’s more to look upon when planning to replace a subwoofer that matches your existing home sound system.

Here are some useful tips.

Best Tips for Subwoofer Replacement

The main specifications of a Subwoofer that matters the most is its power handling capacity with the existing amp.

That being said, it’s not the only thing to consider, there are some other factors that you should also consider when planning to replace your subs.

Check for possible repair options

Most subwoofer components can be repaired in the event of damages.

It can sometimes be worthwhile to inspect the subwoofer components and attempt a simple repair.

Components such as the cone and the voice coil are typically prone to damage due to their constant movement during function.

Over time, subwoofer cones usually go through wear and tear and pre-mature wear outs are common if they are stretched too much.

There’s always a possibility of taping or gluing it back in place in some cases depending on the severity of damage.

However, you will need to use strong and suitable tape or adhesive to accomplish the said task.

There are suitable tapes and adhesives available in the market for repairing speaker cones.

Using ordinary kits can create a negative impact on the cone’s flexibility and if the cone is irreparable you can replace the cone.

Similarly, the voice coils are another repairable component of a subwoofer.

In most cases, rewinding the former with copper wires or simply replacing the voice coil can eliminate the requirement of replacing the entire unit.

Although subwoofer repair is a temporary fix in most cases, it can still enable the subwoofer to be used until a replacement arrives.

Note: If your subwoofer is damaged or burnt it’s obvious that you need a replacement. Typically, a burnt subwoofer can be identified by the burning smell, especially when it’s operational or when you power it on.

Consult with a service professional

Make sure to consult a sound professional before investing in the replacement unit.

A service professional with their knowledge and experience can guide you on many factors that you may not be aware of.

A good knowledgeable service professional can get the existing subwoofer to life and may also eliminate the need to invest in a new unit.

Choosing a powered subwoofer

If you are too concerned about your amp’s power handling abilities, it is a good idea to select a powered or an active subwoofer as a replacement unit.

Powered subwoofers have built-in amps to power their drivers, therefore, they do not rely on external amps or receivers.

Additionally, it will also benefit your existing receiver or amplifier by reducing the amount of power drawn by a passive subwoofer.
