Using your subwoofer with the wrong output size can be bad in terms of sound production and power usage. The size says it all. Therefore, in this article, we will be looking at the different sub sizes and a guide to using them. This will help you match the right subwoofer size to its corresponding room size.
Why this Size Chart
Subwoofers are those low-thumping sound effects that give a rich bassy feeling to your music experience. However, while choosing a subwoofer, the common frequently asked questions are
● Is the Frequency Based on Size?
● Is the room size a factor to determine before choosing the subwoofer
● How do I know the right size for my room
● Can I use a room subwoofer in my car
● How is a small subwoofer different from a big one?
If you have also asked any of these questions before (or probably doing so now) then this size chart is important for you.
Subwoofers are designed to be used with almost any kind of speaker. This means that you can use them with any speaker no matter how larger or small. Therefore, you can use them with a large event speaker, a home theater system, or a portable car rear.
Car Subwoofers size chart
Logically, we know that car speakers are way smaller than most home theater speakers or concert speakers. This indicates that they might require a smaller subwoofer. Car subwoofer can generally be grouped into four; 8-inches; 10-inches; 12-inches; and 15-inches.
Before we go into more details about how this subwoofer differs from each other, here’s a DIY step to know the size of your subwoofer.
Using a ruler or tape rule, measure the subwoofer from one end across to the other end.
This is a quick and straightforward method. Now check out the major characteristics of each size.
Weight: they have the major advantage of being lightweight, making them the easiest pick.
Space consideration: due to the small cone shape, they take up very little space which makes them easy for under the dashboard or the seat.
Bass level and sound quality: most of these small-sized subwoofers have pretty good low-frequency bass with quality sound delivery.
Best music type consideration: it has been reported to deliver better on Jazz and classical music.
Car suitability: small-sized subwoofers are the best fit for small cars. It might not be as small as a Ferrari, but you get the point.
Weight: this is also in the lightweight category
Space consideration: takes up less space and can be used easily under or behind the seat.
Bass level and sound quality: it has a loud bass that is clear and thick. However, the low-frequency bass response does not deliver a good quality
Best music type consideration: they are very ideal for Country music, hard rock, and metal music delivery.
Car suitability: this subwoofer type is suitable for small cars
Weight: this is a bit heavy when compared to the 8-inches subwoofer
Space consideration: well, this is a kind you won’t want to put under your seat because it takes a bit more space.
Bass level and sound quality: plays almost all bass levels perfectly and with a good sound delivery.
Best music type consideration: this is best for pretty much any kind of music, from the slow contemporary to the high hard rock music.
Car suitability: suitable for medium car size.
Weight: this is pretty much the heaviest car subwoofer you can get around.
Space consideration: it takes up a considerably large space and is mostly installed in the car trunk
Bass level and sound quality: it has a long bass resonance that keeps your seat vibrating. But it has been mostly reported to have low sound quality.
Best music type consideration: this kind of speaker is best with hip-hop, techno, R&B, and other related music types.
Car suitability: you should think of bigger cars for proper placement.
Subwoofers Chart FAQs
Is the Frequency Based on Size?
Well, it might look like that because, in most smaller-sized subwoofers, they have better capability to produce low-frequency bass. In contrast, the much larger subwoofers have a larger cone area which is better suited to producing higher notes.
However, other factors –particularly weight- contribute to the kind of frequency range they produce. For example, a subwoofer with lightweight cones is better suited for mid-frequency range while low-frequency sound ranges are best produced by the heavier ones.
How Do I Know the Right Size of a Subwoofer For My Car?
That shouldn’t be too hard! Okay, let me give you some ideas to bail you out. When considering the selection criteria for your car, the first factor to consider -and probably the most important- is the available space.
So, let’s say you have a small car (like a Honda civic) the best kind of subwoofer you should be looking at are those in the 8-10inches size. This is because they fit in easily to any space you have available. Although, this does not give your car size the full power.
There are other factors you might want to consider as well, this includes
- The type of music you love
- Available space in your trunk
- How much bass you want from the subwoofer.
What Size Is My Subwoofer?
This is pretty easy to figure out. Remember your subwoofer size is a measurement of the external diameter.
So, just pick a measuring tape and measure it across. Whether it is a circular or square subwoofer doesn’t matter here, just pick the end of one side and measure it to the other end.
Which Subwoofer is Best for My Room?
Well, this can be a bit challenging. I know we’ve talked a lot about size when choosing a subwoofer but the truth is, there is no clear-cut approach for a room. But some of the criteria and factors people have used include
● The volume of the room
● Expected power output
● Frequency range
● Music type
● And some other personal criteria.
However, how prominent the room is is one of the best factors that has worked well for most people. This is because it helps to produce louder sound and delivers the desired reference point with minimal distortion.
But, for generalization purposes and also putting the reference point in mind, here are some room categorizations that can help you select the best subwoofers.
Now, here is the type of subwoofer you will be needing to enjoy music effectively in your room.
Extra Small room (under 1200 cubic feet)
Subwoofers size: 12-inches
Number of subwoofers: just one will be okay

Maximum Acoustic Response (MAO): 116 decibels
Small room (1200-2000 cubic feet)
Subwoofers size: 10-inches
Number of subwoofers: for efficiency, you will need two of these subwoofers
Wattage: 400watts (remember that this has to be the same in the two subwoofers)
Frequency response: 19-270 frequency sound range
Maximum Acoustic Response (MAO): 118 decibels (x2)
Medium room (2000-4000 cubic feet)
Subwoofers size: 12-inches
Number of subwoofers: about 2 of the subwoofer in the right arrangement will work just fine I’m the room
Wattage: 550watts (the watts has to also be the same in the two subwoofers)

Maximum Acoustic Response (MAO): 128 decibels (x2)
Large room (4000 – 6000 cubic feet)

Number of subwoofers: you will be needing 2 of the subwoofer for better bass effect in the room
Wattage: 800 watts (the bigger the subwoofer the bigger the watts it requires to power it)
Frequency response: 18-270 frequency sound range
Maximum Acoustic Response (MAO): a subwoofer with 124 decibels will be perfect.
Extra-large room (6000 cubic feet and above)
Subwoofers size: 12-13 inches
Number of subwoofers: you will need about 4 of the subwoofer in the room to get the right bass effect
Wattage: 800watts (the watts has to also be the same in all of them)

Maximum Acoustic Response (MAO): 125 decibels acoustic response is enough in each of the subwoofers
Can a Subwoofer be Too Big for a Room?
The answer is No! Sometimes everyone craves that richer sound that keeps the ground shaking. You don’t need an extra-large subwoofer. But if you want it, nothing says you can’t get it; not even your room size!
The only problem you might need to deal with is space. Yes, bigger subwoofers can be challenging when you don’t have a big room. But, if there is a corner you can fix that big boy, then go for it!
Now you can be sure of getting the right subwoofer size that fits perfectly for your car size or your room. Enjoy your music with an extra thumping feeling anywhere you are.
