SVS SoundPath Premium RCA Subwoofer / Audio Cable

The engineering of the SVS SoundPath Subwoofer Cable is what impressed our team of experts. The cold-infused plating and the multi-strand high-purity copper center work together for the best bass audio relays. They are held by an aircraft-grade aluminum shell.

You will also notice that the exterior of the SVS Soundpath subwoofer cables is cotton-braided, making them very resistant to wear and tear. The braiding is also the 5th layer of protection of the RFI shield. The constant pulling and plugging in of the cable will not damage the exterior.

Subwoofer Cables Buyer’s Guide

What should you look for in the best subwoofer cables or speaker cables? Is it just the durability of the RCA connectors, or is there more to it? Our audio engineers have outlined the essential features to consider when looking for an RCA cable. 

Design

The first feature to consider is the design. Whether it’s an analog audio cable or one for digital content, the design will determine how well the RCA cable fits into your system. The type of subwoofer cable you should choose for your home system will depend on the type of sub you have. Do you need splitters for dual subwoofer outputs? If so, then you will need to purchase a splitter. 

Material and Durability

The best subwoofer cable is one that may be subject to a lot of wear. This is when the material comes in. The material the cable features will decide the durability as well. No matter what consumers buy, our sound experts know whether a product can stand the test of time is vital for most.

The subwoofer cable needs to handle the constant pulling and plugging, which is why 24K gold-plated options for the connectors and split tips will provide a tight hold. PVC and heavy-duty rubber make excellent cable exteriors, like the Mediabridge subwoofer cable, because they are resistant to wear and tear.

Our audio team says finding the key between rigidity and flexibility for the coaxial cable might take time. You want the subwoofer cable to be bendable and easy to manage, especially if you intend on coiling or meandering the speaker wire through your setup.

Audio cables that are too rigid will not be simple to handle. On the other hand, our team cautions that RCA cables that are too flexible will easily bend and interfere with the audio quality.

The Mediabridge Ultra Series subwoofer cable is an excellent example of a pliable exterior but is also stiff enough to remain taut if necessary.

Thickness

Thickness can be a concern for many people as there is the impression that a thin subwoofer cable is not as sturdy. Although this is true to some extent, our sonic engineers still place importance on the materials used. Keep in mind that the thickness will also affect the workability of the subwoofer cable around obstacles. 

In other words, a thinner cable is usually more pliable, while a thicker one is usually stiffer.

Length

Many consumers focus on the construction and materials of the best subwoofer cable that they forget about the length. Depending on how your room and sound system are being set up, people will need different cable lengths. 

Our team has many options that have varying reaches, so it’s important to consider which is the best one for you.

Some of you may think that purchasing a longer cable just in case you require multi-channel duties, but our experts advise against that. You will be left with a ton of extra cable just coiling around the place, which could be a tripping hazard. Not to mention, it can be an eyesore.

Having lots of leftover cables can also get in the way of the placement and the overall setup of your entertainment room. 

The electrical signals will also need to travel further through the RCA ports, which isn’t ideal for precise audio quality. It would be best to purchase the perfect length needed for your system. 

Conductors

The conductors are usually located in the center of the subwoofer cable and are sometimes referred to as the core. It’s a contact point for the audio signal from the source device to your speakers.

Subpar subwoofer cables will usually transmit signal frequencies slower than well-made products. Copper conductors are preferred for speed, and reliability plus they are very lightweight. Our experts say durability is also a consideration for the conductors.

Look for corrosion-resistant subwoofer cables like the Mediabridge Ultra Series subwoofer cable, for example. Don’t think that all conductors made of copper are the same because some brands may use innovative methods to enhance the conductivity, such as oxygen-free copper. 

Shielding

Shielding is more than crucial for the sound quality of the audio cable. Properly shielded subwoofer cables can prevent RF interference, radio frequency interference, and more. 

Aluminum braiding is our top choice for subwoofer cable shielding, and the more layers it has, the better. The shielding also ties into the thickness of the cable because an audio cable that is too thin will usually have less shielding than a thicker one. 

Sub cables can offer more than just one form of shielding, and some can provide many layers. Of course, if you want top-quality cables that can guarantee protection against any sort of signal tampering, choose one that has multiple layers of defense. 

RCA vs Coaxial Cables

Is there a difference between RCA and coaxial cables? Let’s start by breaking down what RCA cables are. RCA cables have slowly become obsolete, making way for the far more efficient HDMI [1].

RCA types have separate cables for audio and video, while HDMI consolidates the two functions – hence why they are referred to as a one-cable connection. The term RCA refers to the RCA connectors and not the cable. 

Coaxial cables are more common than RCA, and we use them for devices such as satellite receivers. They are affordable, easy to install and use, and can handle high data loads. That’s not to say there are no disadvantages because they are more susceptible to the constant humming sound.

Traditionally, an RCA wire lacks the shielding coaxial cables can offer, and they cannot handle the load the latter can. They may look the same outside, but the inner workings, such as the conductor, set them apart with coaxial cables as our team’s preferred and recommended option. 

FAQ

Does a subwoofer need a special cable?

Yes, a subwoofer needs a special cable if you want to get the best sound. Frequently, manufacturers use RCA as subwoofer cables, but some may add special features like better shielding. The subwoofer cable you choose will depend on your subwoofer type and the rest of your system to determine. 

Does a good subwoofer cable make a difference?

Yes, a good subwoofer cable will make a difference. The difference is anything but nominal. Better shielding, durability, the right length, solid conductors, and secure connectors will distinguish between precise bass and disappointing relays. For crystal clear bass without hums and buzzing, pick a good subwoofer cable. 

What type of cable is used for subwoofer?

The type of cable you can use can be coaxial or RCA cable for the subwoofer. The type will depend on your subwoofer connections, but the two are often interchangeable. Picking a thick and sturdy cable for your home theater bass will make all the difference. We suggest looking for one that is adequately shielded with wear-resistant materials.
