Subwoofer Size Chart

Matching the right subwoofer size with room sizes is very important. Equally, you need to match the subwoofer with playback devices to ensure the subwoofer does not strain to reproduce the sound. In this article, we look at the subwoofer size chart and related details.

Subwoofer Size Chart

Subwoofers perform best in reproducing low-frequency sounds. However, choosing the best subwoofer size should not be a painful process. Some of the factors you will need to consider when selecting subwoofer sizes are room size, placement options, budget, among other factors.

Besides home listening, subwoofers form a significant part of car sound systems, especially for those who love listening to music while on the road.

Whether you like it placed on the rear or sideways, subwoofers are a good listening experience. They will help fill your car or room with surround sound if adequately balanced with other speaker units and driven by a substantive amp.

Most people with poor subwoofer experiences or those who never used an excellent subwoofer before tend to think that subwoofers are meant to be on the “noisy” end. This is not true. Subwoofers are intended to create some extent of audio perfection by rounding out the entire sound of your music.

Whether you are watching a movie or just listening to some music, you are missing out on almost half of your ideal listening experience if you have not incorporated a subwoofer. Therefore, it is imperative that realistic sound is dependent on a good, balanced subwoofer.

Car Subwoofer Sizes With Features

Generally, subwoofer size charts consist of four different types of subwoofers. Here, we have divided the subwoofers into 8, 10, 12, and 15 inches and added the key features together with the best-suited cars for each category.

But how are subwoofer sizes measured? This is a straightforward DIY process. Measure the distance from one end of the subwoofer to the other end of the edge.

For instance, if you have a 10-inch subwoofer, the subwoofer is 10 inches in diameter. Mounting holes will, however, vary depending on the manufacturer.

Study the subwoofer chart below for the best sizes with high-quality sound performance.

Subwoofer sizes 8 inches 10 inches 12 inches 15 inches
Weight LightweightLightweightA little bit heavyHeavier
Space consumption Smaller cone area takes up less spaceLess spaceA little bit more spaceLarger space
Watts 300 - 1200150 - 120050 – 1200 or 1300600 - 5000
Bass production and sound quality It Plays low-frequency sound perfectly and the sound quality is very goodThe bass is loud, crystal clear, and quicker in the punch. The Low-frequency response is not so good. Generates low-frequency notes very well and the sound is high-quality and perfectly loud.The bass resonance produced is long. The sound quality is however low.
Music type Best for classic and jazz musicBest for rock, country, and metal musicBest for a variety of music but plays the snappy drums of rock music much betterBest for rap, techno, and r&b type of music
Suitable cars Good for small-sized carsSmall carsMedium-sized carsBest for bigger cars for proper placement

Subwoofer Size Chart Notes 

We have provided additional notes on the subwoofer size chart below. 

Frequency-Based On Size 

Generally, the smaller subwoofer sizes, i.e., 8-inch, are designed to create low notes. However, larger sizes such as the size 15 subwoofers are built to create higher notes due to their large cone areas. 

On the other hand, mid-frequency sound ranges are best reproduced by lightweight cones. On the other hand, Heavier cones are best suited to reproduce low-frequency sound ranges. 

What Size Subwoofer Do I Need For My Car? 

Generally, the subwoofer size that suits your car depends on several factors. Let’s look at each size subwoofer and the right choice of car.

Subwoofer Size For Small Cars

The size of the car is a key factor when choosing the right subwoofer size. If you have a small car, it is important to consider the space available for the placement of the subwoofer. In this case, it will be more ideal to go for the 8-inch subwoofer. 

Other things to consider when choosing the right subwoofer size include:

  • Type of music 
  • Shape and amount of space in the trunk 
  • Bass requirements 

What Size Is My Subwoofer?

As we already stated, the size of a subwoofer is the measure of the extent of the external diameter of the circular metal frame around the front of the driver. The diameter, therefore, included both the moving and non-moving parts of the subwoofer. 

Woofer Size For Room Size 

Getting the right woofer size for your room can be a little challenging. Before you make the final decision, you need to consider elements such as room volume and concept, power output, frequency range, and explosiveness, among others. 

There is no standard rule for determining which size subwoofer is for a particular room size. This is because several variables in play generally need to be put together to decide the right woofer size. 

Most rooms are considered small compared to dedicated listening spaces such as commercial movie theaters.

However, because we generally intend to hit reference levels with minimal distortion or compression, having a more prominent room helps you get a much louder sound and takes you much closer to hitting the reference levels. 

Here are the general room categories:

  • Extra-small – under 1200 cubic foot 
  • Small – 1200 – 2000 cubic foot
  • Medium – 2000 – 4000 cubic foot 
  • Larger – 4000 – 6000 cubic foot 
  • Extra-large – over 6000 cubic foot 

Subwoofer For 3000 Cubic Foot Room

3000 cubic foot rooms fall in the medium room category. It is better to use 12-inch subwoofers for better sound performance for this room size. However, two 12-inch subwoofers should be used instead of one for the best results. 

Subwoofer For 4000 Cubic Foot Room

This room category is slightly more than the medium category. It is, therefore, classified as large. Large room sizes require 15-inch subwoofers for the best sound quality and bass performance.

In addition, if you intend to have the best sound experience, we recommend using two 15-inch subwoofers in this kind of room size. 

Conclusion 

Finally, getting the right subwoofer size requires that you take proper measurements of the room size and the diameter of the woofer. This will help you match the room size correctly with the subwoofer for the best sound and bass performance.
