If you’re in the market for the best subwoofer cable, then you’re at the right place.
One of the most common things people tend to overlook when setting up their home theater is not the quality of equipment you have or where the speakers are placed. It is the quality of signal strength sent to these speakers that matters the most.
A weak signal strength automatically leads to poor quality of sound and the only way you can avoid this is by purchasing a good set of high-quality cables. When it comes to your subwoofer you have to be extra careful so you don’t get unwanted distortion from low-quality cables.
So, which is the best subwoofer cable?
The best subwoofer cable you can pick up today is the Audioquest Black Lab RCA Subwoofer cable. This unit uses long-grain copper plugs that help enhance your audio and uses a NDS (noise dissipation system) to prevent any unwanted buzz or static from building up. The cable is quite affordable and is backed by a 5-year warranty which is one of the reasons why we love this subwoofer cable.
So I’ve put together a couple of my favorite cables that are of top-notch quality to bring out the best in your home theater system.

What to Look for When Choosing a Subwoofer Cable?
There are many factors to consider when buying a subwoofer cable. The following points are key things to look at when choosing a subwoofer cable for your needs.
- Shielding and Noise – When using a cable to transmit audio you need to remember that it’s subjected to all kinds of interference. Cables that are shielded prevent any interference,static or hums that might arise This happens when the cable wires are lose and exposed. A good quality cable will be well shielded and regardless of the fit, you should not hear any noise.
- Thickness – The thickness of the cable also helps prolong the life of the cable. Whatever you do, stick to a cable that is between 20-25 AWG as this is ideal for most home theater subwoofers.
- Metal used in the Cable – Subwoofer cable pins are generally made from copper and silver. The main difference is the quality of audio and the overall price of the cable. Copper cables are cheaper and don’t have the conducting capabilities like silver cables, but silver cables cost way more than copper cables.
- Cable Length – The length of the cable depends directly on how you want to arrange your subwoofer and home theater. Try and keep the cables as short as possible so there is no electrical delay or loss in resistance.
Are RCA and Coaxial Cables the Same?
Though RCA cables look like Coaxial cables in some ways, there are a couple of differences in how they function.
- RCA cables transmit analog and not digital signals
- RCA cables are thinner and more affordable than Coaxial cables
- They cover a narrow bandwidth as compared to Coaxial
Coaxial cables transmit digital signals and are shielded to prevent distortions and static. They are ideal for connecting your TV with your AMP or Soundbar.

Can I connect multiple subwoofers together?
In short, Yes you can connect multiple subwoofers together. However this depends on the make, model and power output of the subwoofer. You can connect more than one subwoofer together in one of two ways; through a single RCA Y-adapter (parallel) or through dual outputs where each sub is connected to a single terminal.
If your subwoofer comes with a RCA line-out and a line-in, you can connect your amp to the first subwoofer via the pre-out and to the second subwoofer via the line-out.
Can I use these subwoofer cables for my normal speakers?
Yes, It is possible to use the cables for your regular speakers provided if they have an RCA input connection. Most home theater systems come with copper lead to switch connections then it wouldn’t be possible for you to use these cables. If that’s your cause you can search for high-quality speaker wires than cable which should do the same.
Does having a longer length of cable drop signal strength or lag?
Yes, it does but this is only if you are using normal cables that you receive from your stock home theater installment. The whole point of the above cables is to have your desired length of the cable without losing signal strength. So if you are planning for a large wide space set up. You need these high-quality cables.
Do subwoofer cables make a difference in the sound quality?
Yes, subwoofer cables do enhance the overall quality of the sound that’s plying. However, you have to pick the most appropriate subwoofer cable for your needs as they are all designed differently and have different properties.
Do subwoofoers use coaxial cables?
Yes they do. Since coaxial cables are 75ohm cables, similar to the ones supported by subwoofers, they will work without any hiccups.
