1 Ohm Vs 4 Ohm Subwoofer

Subwoofers are essential to any sound system, whether for a home theatre or in a car. They are responsible for producing low-frequency sounds that add depth and richness to music and other audio content. When looking for subwoofers, you’ll often encounter two common types – 1-ohm and 4-ohm subwoofers. In this article, we’ll delve into the differences between these two types and help you understand which is best suited for your needs.

1 Ohm Vs 4 Ohm Subwoofer

Before the comparison, it’s essential to understand what ohms are. An ohm is a unit of electrical resistance that measures how much electricity can flow through a particular object. In simpler terms, ohms determine how much power a subwoofer can handle. The lower the ohm rating, the more electricity it can run, resulting in louder and more powerful sound output. On the other hand, a higher ohm rating means that the subwoofer can take less power, resulting in lower sound output.

1 Ohm Vs 4 Ohm Subwoofer

1 Ohm Subwoofers

As the name suggests, 1-ohm subwoofers have an impedance of just 1 ohm. They are known for their ability to handle large amounts of electricity and produce powerful bass sounds. These subwoofers are usually more expensive than their 4-ohm counterparts as they require high-quality materials and precise construction to support such low resistance. However, they offer better sound quality and performance because they can handle more power. They are an excellent choice for those looking for a loud and intense bass experience.

4 Ohm Subwoofers

On the other hand, 4-ohm subwoofers have a higher impedance of 4 ohms. They require less power and can be connected to most amplifiers without issues. These subwoofers are generally more affordable than their lower ohm counterparts as they don’t need as high-quality materials or complex construction. However, because they can handle less power, they offer lower sound output and may produce a different level of depth in bass sounds. 4-ohm subwoofers are an excellent option for those on a budget or smaller good systems that don’t require mighty bass.

Which One to Choose

Now that we understand the differences between 1-ohm and 4-ohm subwoofers, the question arises – which one should you choose? The answer depends on your specific needs and budget. If you’re looking for a powerful and intense bass experience, a 1-ohm subwoofer is the way to go. They are also a must-have if you have a high-powered amplifier. However, keep in mind that they can be pretty expensive. On the other hand, if you’re on a budget or have a minor sound system, a 4-ohm subwoofer will suffice. They are also more versatile and can be connected to various amplifiers without issues.

What sounds better, 1 ohm or 4 ohm?

The answer to this question depends on what you plan to use the 1 or 4 ohms for. Generally speaking, a higher impedance (ohm) results in less power output and usually leads to better sound quality, with distortion being kept at a minimum. Conversely, lower impedances produce more power output but can lead to increased distortion due to their higher current load capabilities. 

Regarding 1 ohm vs 4 ohms, several factors come into play when choosing which is better for your application. A typical amplifier will be rated by its maximum wattage output; however, it’s essential to consider its wattage rating and impedance rating – meaning how much power it can generate without distorting or affecting your overall audio performance negatively. 

Is 1 ohm best for subs?

When it comes to choosing the correct impedance for your subwoofer, the answer can be a complex one. It depends on several factors, including the type of amplifier, power requirements, and speaker configuration. The short answer is that 1 ohm is often considered a good choice for those looking to get maximum power out of their subs, but it’s essential to understand why this could be ideal in some cases while detrimental in others.

For starters, many amplifiers can handle up to 2 or 4 ohms safely without risk of damage. This means that you have a variety of impedances available depending on what type and model you own. When using an amp with an impedance range lower than 4 ohms, however, running at 1 ohm will offer more power output than any other number due to the decrease in resistance causing more current flow through the circuit – meaning louder volume levels can be achieved from the same amplifier when operated at 1ohm compared to any other value higher than that (such as 2 6 8, etc.). 


When it comes to choosing between 1-ohm and 4-ohm subwoofers, there is no clear winner. It all depends on your specific needs and budget. If you want powerful bass sounds and have a high-powered amplifier, go for a 1-ohm subwoofer. Otherwise, a 4-ohm subwoofer will do just fine. Whichever option you go for, ensure that you purchase from reputable brands and choose quality materials to get the best possible sound experience. Happy listening! So, research and select the subwoofer that best suits your needs to enhance your audio experience.
