12 Best Subwoofer Cable Reviews in 2021

If you have recently bought a new subwoofer for your audio system, you have probably realized that you also need a decent subwoofer cable for the system. While a lot of subwoofer manufacturers include the cable with the unit, sometimes, the cables are not available in the package. And even if you get the cable, it might not be a high-quality cable which can interfere with the output and reduce the quality.

With a simple cable upgrade, you can get much better output from your subwoofer. The subwoofer cables allow you to connect the subwoofer to any compatible audio system of your choice. And if the cable offers high-quality data transmission, you will be getting a rich bass output and an overall enjoyable quality at all times. If you are thinking about getting a new cable, consider the following aspects before you do so.

  • Length: While buying any type of cable, you need to consider its length so that you can make sure that it is enough for connecting the devices properly without needing to move the items around. As for a subwoofer, you should prefer a long cable so that you can rearrange the position later if needed without worrying about cable length.
  • Connector Type: The end of the subwoofer cables are the connectors that connect the subwoofer with the source. The type of the connector determines the connectivity and signal transmission capacity of the cable. Also, you should prefer the connectors that have gold plating on top that helps to avoid problems like rusting and corrosion which can severely degrade the quality of the signal.
  • Warranty: There is a high chance that you are looking for a cable because your previous cable is damaged and not offering the best quality or any output at all. This can be avoided with your next purchase if you prefer an option that is reliable for the long term. You can get an idea about the reliability of the product by checking its warranty period.

Buying Guide For The Best Subwoofer cable

Even though a lot of subwoofers come with a cable, you should consider getting a high-end cable from one of our options from these best subwoofer cables to get the best results from your subwoofer. You can use the cable for connecting your subwoofer to various devices.

You can also have a separate cable permanently connected to certain devices which offers faster connections. All of the items mentioned in this article have their specifications and details explained in a brief review. But, if you want to know more about subwoofer cables, take a look at our buying guide for the best subwoofer cables given right here.

Length of the Cable

Most subwoofers are shipped with subwoofer cables included in the package. But the quality of the cable varies for different manufacturers, and so does its length. Depending upon your application, you might be needing a long cable to connect the devices properly, or a short cable to avoid unnecessary mess. In any case, you will find the best subwoofer on our article today as we are offering a range of options varying from 4 feet all the way up to 33 feet. Such a high range is definitely suitable for all types of applications whether you are using a subwoofer on your home theatre or with desktop reference monitors.

Connector Type

While getting a subwoofer cable, you should definitely check the connector type of the cable and what types of connections it supports. Almost all subwoofer cables will look pretty much identical as the ports are the same for both types of connections. But, some cables offer only RCA connections whereas some advanced cables support both RCA as well as coaxial connections. The latter options are more versatile as you will be able to use the same cable for both types of connections. Other than that, you need to check the ports of the cable and make sure they are gold plated and offer additional grooves for a secured connection.

Thickness and Flexibility

The only measure of the durability of a cable is its thickness and flexibility. Once connected, the cables mostly remain stationary without a lot of movement for a long time. Therefore, it could cause problems with the cables, especially if it is twisted at the time of application. But if the cable is flexible, you can easily move the cable around and connect it with the subwoofer swiftly. As for the thickness, it prevents the cable from wearing down quickly. But keep in mind that both of these factors oppose each other. An overly thick cable will not be as flexible as a thinner option. But, it would certainly be more durable in the long run.


The reliability is a major issue for these cables. A lot can go wrong with a subwoofer cable. The connectors can get damaged, the cable can get twisted internally and break, or there can be internal damage that interrupts the signal transmissions. As these cables cannot be repaired, you will have to rely on the service offered by the manufacturer to replace the cable. Therefore, it helps if you have a long warranty period on the cable before you buy it. It gives you assurance and allows you to use the cable without worrying about damage. Some brands also offer a lifetime warranty period on their cables as they are built to last.


Q. Does audio quality from my subwoofer depend upon the audio cable?

Technically, the overall performance of your subwoofer depends upon the quality of the subwoofer itself as well as the driver that is installed in it. But, it is only operating on the signals that it is receiving through the cable. Thus, the cable also plays an important role in this scenario. Generally, if the cable is rusted or bent, you will notice a disturbance in the audio output which will reduce the performance of your subwoofer significantly.

Q. What is the difference between coaxial and RCA cables?

Coaxial and RCA cables look quite similar. But, They are quite different in terms of application as RCA cables transmit analog signals whereas coaxial cables carry a digital signal. RCA cables are slimmer in comparison but have a lesser bandwidth capacity than coaxial cables.

RCA cables are also comparatively unstable and can be easily disrupted because of slight interference from the outside. Thus, you should either choose coaxial cables or dual shielded RCA cables.

Q. Is it possible to connect more than 1 subwoofer in the audio system?

You can connect multiple subwoofers to the same audio system to increase the low-end output. However, it sort of disrupts the balance of the output and the sound becomes heavy on the bass side. Instead of connecting multiple subwoofers, you should prefer a single high-powered option that you can place at the center of the system.

But, if you want a surround experience with the low-end sound, you can invest in a handful of low-capacity subwoofers and connect them to your system after installing them in different corners.


The main task of a subwoofer cable is to deliver the line-level signal from the source to the subwoofer which generally lies between 0.3 to 0.4 volts. In this case, the source can be anything such as an amplifier, AV receiver, or your home theater.

By investing in a good subwoofer cable, you can keep the surrounding noise as well as interference to a minimum level which lets you enjoy a high-quality output on your subwoofers. If you want to know more about the best subwoofer cables, kindly go through our picks mentioned above along with our buying guide for the best subwoofer cables.
