There are a lot of different opinions on which is better: subwoofer cable or RCA. Some people say that you should always use a subwoofer cable, while others say that RCAs work just as well.

So, which is the right choice for you? In this blog post, we’ll explore the difference between subwoofer cable and RCA and help you decide which option is best for your needs. Stay tuned!

What is subwoofer?

A subwoofer is a type of loudspeaker that reproduces low-pitched audio frequencies known as bass and sub-bass.

The typical frequency range for a subwoofer is 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-approved systems. Subwoofers are intended to augment the low frequency range of loudspeakers covering higher frequency bands.

Keep in mind choosing a subwoofer cable

When choosing a subwoofer cable, it is important to consider the length, gauge (thickness), and material. The following sections will explore these factors in more detail.


The length of the subwoofer cable is an important consideration because it determines how far the signal has to travel. The longer the cable, the greater the risk of signal loss. For this reason, it is best to choose a cable that is as short as possible. However, if you need a long cable, there are ways to minimize signal loss, such as using a thicker gauge (see below) or running the cable through conduit.


The thickness of the subwoofer cable is measured in gauge. The higher the gauge, the thicker the cable. A thicker cable has less resistance and can carry a stronger signal over a longer distance without losing any quality. For this reason, it is best to choose a cable with a higher gauge. However, thicker cables are more expensive and may be difficult to route through your home theater system.


The material of the subwoofer cable is also an important consideration. Subwoofer cables are typically made from copper, silver-plated copper, or oxygen-free copper. Copper is the most common material because it is relatively inexpensive and has good conductivity. Silver-plated copper is more expensive but has better conductivity than copper. Oxygen-free copper is the most expensive but has the best conductivity of all three materials.

What are the types of subwoofer cables?

There are three types of subwoofer cables: stereo phone cables, mono phone cables and speaker wire.

  • Stereo phone cables: The most common type of cable, these have two audio channels (left and right) and are color-coded red and white.
  • Mono phone cables: These have a single audio channel and are typically used to connect a subwoofer to an amplifier.
  • Speaker wire: This type of wire is used to connect speakers to an amplifier. It is typically thicker than other types of audio wire and has two conductors (positive and negative).

What is RCA?

RCA is a type of connector commonly used for audio and video equipment. It is also known as a phono connector or cinch connector.

The name “RCA” derives from the Radio Corporation of America, which introduced the design by the early 1940s for internal connection of the pickup to the chassis in home radio-phonograph consoles. It was originally a low-cost, simple design, intended only for mating and disconnection when servicing the console. Refinement came with later designs, although they remained compatible.

What are the types of RCA cables?

As we mentioned before, RCA cables are used to connect audio and video components. They typically have two or three conductors and are often color-coded red, white, and yellow. The most common type of RCA cable is the audio cable, which has two conductors (left and right) and is color-coded red and white.

Video RCA cables are used to connect video components, such as TVs and DVD players, to monitors and projectors. They typically have three conductors (red, green, blue) and are often color-coded red, white, yellow. In addition to the standard video cable, there is also the component video cable, which has five conductors (red, green, blue, yellow, white) and is color-coded red, green, blue, and two whites.

HDMI cables are the newest type of cable on the market and are used to connect HDTVs, Blu-ray players, game consoles, and other high-definition devices. HDMI cables have nineteen conductors and are often color-coded black.

types of subwoofer cables

What are the differences between subwoofers and RCA cables?

The main difference between subwoofer and RCA cables is that subwoofer cables are used to connect subwoofers to amplifiers, while RCA cables are used to connect audio and video components. Subwoofer cables typically have two conductors (left and right), while RCA cables can have two or three conductors. Another difference is that subwoofer cables are typically thicker than RCA cables. Finally, subwoofer cables typically have a lower frequency range than RCA cables.

So, which is better? Subwoofer or RCA?

There is no clear answer as to which is better, subwoofer or RCA. It depends on your specific needs and preferences. If you need to connect a subwoofer to an amplifier, then a subwoofer cable is the best option. If you need to connect audio or video components, then an RCA cable is the best option. Ultimately, it is up to you to decide which type of cable is best for your needs.
