Difference between Sealed and Ported Box

There are many different types of subwoofer enclosures, each with its own advantages and disadvantages. In this blog post, we will discuss the difference between sealed and ported boxes. We will also explain how both of these types of boxes work and what type of music they are best suited for. Finally, we will provide you with a few tips on choosing the right enclosure for your needs. Let’s get started!

What is Sealed Box?

Sealed box subwoofer enclosures are designed to prevent sound from escaping the box, as well as to prevent outside sound from entering the box. Sealed boxes are typically used in applications where space is limited, or where maximum bass response is desired. Sealed boxes are also typically more expensive than other types of subwoofer enclosures, due to the additional labor and materials required to build them.

What is Ported Box?

Ported box subwoofer enclosures are a type of speaker box that uses a port to increase the low frequency output of the enclosure. The port allows air to move in and out of the box, which amplifies the low frequency sound waves produced by the speaker. Ported boxes are typically larger than sealed boxes, and they require more power to drive. However, they are well-suited for music that has a lot of bass, such as rap and EDM. Ported box subwoofer enclosures are a popular choice for car audio systems, home theater systems, and club sound systems.

Difference between Sealed and Ported Box

Sealed and ported boxes are the two most common types of subwoofer enclosures. Sealed boxes are typically smaller and more compact, making them a good choice for installations where space is limited. They also tend to have deeper, more precise bass response. Ported boxes are larger and require more air space, but they can produce louder, more powerful bass.

When choosing between a sealed and ported box, it’s important to consider the size of the enclosure, the power of the amplifier, and the type of music you plan to listen to. Sealed boxes are better suited for music with tight, punchy bass, while ported boxes are better for music with deep, thunderous bass. Ultimately, the best way to decide which type of box is right for you is to experiment and see what sounds best in your car.


In the end, it is up to you to decide which type of enclosure will work best for your needs. If you are looking for louder bass and don’t mind sacrificing a bit of clarity, then a ported box may be right for you. If, however, sound quality is more important than sheer power and you have the space available, then a sealed enclosure may be a better option.
