What You Should Know About Subwoofer Size Chart? [Ultimate Guide]

Everything about Subwoofer Size Chart. We promise to discuss various categories and divisions of car subwoofers based on their size and dimensions. We get a lot of emails from people who are unsure about what size subwoofer is best for their car and situation. As a result, this Subwoofer Size Chart should be useful.

For music enthusiasts, subwoofers are an essential component of a car's sound system. They generate the bass (which can cause the car to shake) and allow you to feel (rather than just hear) the vibrations of music. Subwoofers are required because stereo speakers have no room for bass.

Key takeaway

Subwoofer size charts are useful for determining the right size of subwoofer for a given application. Component subs usually range in size from 8″ to 15″, with 12 inches being the most common size. The Bassaholic Subwoofer Room Size Rating Protocol is a useful tool for determining the appropriate subwoofer size based on room volume and desired sound pressure level.

Audio perfection is created by properly tuned car stereo systems with a subwoofer. Many people have misunderstood the subwoofer's function. They believe subwoofers will rattle their teeth, shatter their windows, and shake their bones. However, my dear readers, you are completely incorrect.


Your subwoofer produces low-frequency sounds that complement the overall sound of your music. You're missing out on half of your music if you don't have a subwoofer. As a result, realistic sound is dependent on a well-balanced subwoofer that adds good quality bass to the overall sound.

Automobiles come in a variety of shapes, sizes, flavors, and variants. Subwoofers, speakers, and amplifiers all play a role. This fact alone allows everyone to get exactly what they want, but what good is it if you don't know what you want because you don't understand what it all means?

This type of confusion is common in the world and can turn even the most knowledgeable people into babbling messes. I'm especially excited to inform you about the various subwoofer sizes because this appears to be a common source of confusion for many people.

What Should You Know About Subwoofer Size Chart?

The four most common subwoofer sizes are 8 inches, 10 inches, 12 inches, and 15 inches.

1. 8-Inch Subwoofers: These are the standard small woofers that are commonly found in car sound systems. They have been dubbed the smallest woofer capable of producing good bass. 8-inch subwoofers add a bit of rumble, or flavor, to your car's music without taking up too much space.

2. 10-Inch Subwoofers: These are popular in smaller cars due to their responsiveness and compact size. They can't hit the lower frequencies as well as a 12″ woofer, but they're much faster.

3. 12-Inch Subwoofers: The 12-inch subwoofer is by far the most common; it provides an excellent balance of accuracy and loudness. They hit the lower notes without using a lot of force. A 12″ woofer can be punchy or boomy; this is where your box comes in to fine-tune your woofer to your exact specifications.

4. 15-Inch Subwoofers: Due to their large cone area, these monstrous subwoofers produce lower frequencies better than the latter woofers. 15-inch subwoofers can easily handle long resonant bass notes and are an excellent choice for bass heads. However, because of the cone size and weight, the magnet has a difficult time slowing the cone down, so sound quality suffers but boomy bass shines through.


The Subwoofer Size Chart includes four different subwoofer types.

  • I classified subwoofers into four sizes: 8 inches, 10 inches, 12 inches, and 15 inches.
  • Along with this, I've included all of the important features as well as the best-suited cars for each subwoofer size.
  • Subwoofer sizes are measured from one end to the other, with the edges carefully marked. This means that an 8-inch subwoofer will have a full 8-inch diameter.
  • However, the diameter of the mounting hole may vary depending on the manufacturer.

This subwoofer size chart is for you if you're looking for a good-sized, high-quality subwoofer for your car. It is hoped that it will assist you in making the correct subwoofer size selection for your vehicle.

Frequency Based on Size

  • The small 8-inch subwoofer is intended to produce low notes.
  • Larger 15-inch subwoofers, on the other hand, are designed to produce higher notes due to their larger cone area.
  • Mid-frequency ranges appear to be best produced by lightweight cones, while low-frequency ranges appear to be best produced by heavier cones.

15 Inch Subwoofer Size Benefits

  • If you want more bass notes, a 15-inch subwoofer is the way to go.
  • Rap music, for example, features heavily synthesized bass, which benefits from a 15-inch subwoofer.
  • A large volume of air is required for the production of good bass music, and 15-inch subwoofers are the best for this purpose.
  • A factory-installed speaker or even the best aftermarket speakers cannot reproduce this sound. To complete heavy bass sounds, a large subwoofer is required.


Finally, after you've chosen the best subwoofer for your music needs and properly fitted them. Then you'll need to balance everything with a suitable amplifier.

To complete your sound, your amplifier's mid-range, high-range, and volume tuning should be properly tuned. However, keep in mind that the most important thing is first to purchase a subwoofer that matches your musical tastes.


Of course, you'll need to think about how much space your car has for a subwoofer. Choose an 8-inch subwoofer if you have a small car. When shopping for a car subwoofer, consider the trunk space as well as your music needs.

  • You should also properly mount them in the trunk.
  • Also, check out this article if you want to get more bass out of your car subwoofer.

Frequently Asked Questions

How do I know what size subwoofer to buy?

The larger your subwoofer, the more space you'll need around it. A 12-inch subwoofer requires 1.25 cubic feet of volume space. Volume recommendations for a 10-inch woofer are 0.625 cubic feet and 0.375 cubic feet for an 8-inch subwoofer.

Is a 10 or 12 inch subwoofer better?

If size, power, space, and budget aren't an issue, 12 inch subwoofers are the way to go. If 12 inch subwoofers aren't an option, go with 10 inch subwoofers. If 10-inch subwoofers aren't an option, opt for 8-inch subwoofers.

Should I get 12 or 15 inch subwoofers?

The question of whether 15-inch subwoofers have a better base than 12-inch subwoofers is not easily answered. The truth is that “better” is a matter of personal preference. Because 15-inch subwoofers are larger and displace more air than 12-inch subwoofers, the 12-inch subwoofer will have a crisper, sharper sound than the larger ones.
