Choosing a subwoofer box Ported vs Sealed is not an easy decision but significant to know. Many factors come into play when picking the perfect box for your vehicle. For example, do you want to be able to feel the bass and have plenty of room in the trunk? Or do you want maximum output without any sacrifice?

There are many options on what type of box to use. This article will help you to decide between a sealed or ported design. We have come up with our list of pros and cons to help narrow down what will work best for your needs.


Ported subwoofer box design

A ported subwoofer box is a type of speaker enclosure that uses a port to provide additional low-frequency audio waves. Air pressure fluctuations produce sound waves, and the proper size and shape of a speaker enclosure will help maximize these sound waves.


A ported car subwoofer box has additional dampening material (called “port”) in the corner opposite the woofer. The dampening material is designed to absorb as much energy from the sound waves traveling through it backward before these waves get to the woofer and speaker cones so that they don’t end up shaking too much.

The result is a smoother, tighter bass or boom without undertones. In addition, ported subwoofers can produce considerably more low-frequency output because few oscillations stop them out in their tracks or cause them to regenerate (revert back into audible tone).


A sealed subwoofer box stores the most air possible and is typically made out of rigid or semi-rigid materials. A sealed subwoofer box is a small, relatively heavy enclosed space that can be stuffed with foam or other materials to help absorb any sound created by the speaker itself.


The sealed car subwoofer box is designed to minimize the amount of air that can leak from the speaker when it’s pushed.

The sealed car subwoofer box also helps minimize distortion by preventing air pressure from pushing too much on the speaker and distorting the sound coming out at high volumes. This is accomplished in two ways: first, detailing how big a hole in it should be for power cables.

And then secondly, by making up with volume what the hole leaves open so that there’s virtually no airflow through the sealed car subwoofer except during music playback.

Now a question raises in mind what better sealed or ported sub box? So let’s dive in to understand completely.

Here we will talk about comparing ported and sealed subwoofer boxes and their pros and cons.


Ported car Enclosures are a great way to protect your vehicle from the elements, but they also have drawbacks. The pros and cons of Ported car Enclosures will be outlined here, so you can make an informed decision on whether or not Ported car Enclosure is right for you!


  • Ported car Enclosures protect your vehicle from the elements and are an inexpensive option for protecting a single automobile.

  • Ported car Enclosure is also great for items that need to stay dry, like motorcycles or other equipment you have stored in your backyard.

  • Ported car Enclosures can be easily installed by even novice do-it-yourselfers. Ported car Enclosures can be installed on your schedule, even if you only have a few hours available to work outside the house.

  • Ported car Enclosure is made from durable materials and will stand up against harsh weather conditions for years with little maintenance required! In easy words, Ported subs theoretically can run cooler because only air is passing through them, but can also run hotter if not designed according to current standards.

  • Because of this, ported boxes are significantly larger and more efficient when it comes to power.


  • Ported car Enclosures are not the best option if you want to keep people from accessing your vehicle.

  • Ported car Enclosures have small openings that only allow one person access at a time, so it would be difficult for multiple individuals to pull off any theft attempts!

  • Ported car Enclosure can also create problems with the ventilation in certain weather conditions because ported subs require longer vents such as those found in-car audio (usually about an inch)

  • Ported car Enclosure is also difficult to install on a Ported car Enclosures located within an attached garage.

  • Ported car Enclosure may not be the best option if you live in an extremely hot climate, as Ported car Enclosures can heat up and create further problems with ventilation!

A car subwoofer box is a sealed enclosure designed to take in the sound waves created by your car’s speakers and produce an amplified, bass-rich sound. We will explore the various pros and cons of this type of speaker box.


  • Sealed car subwoofer box pros include the ability to produce clear sound, an attractive design that doesn’t take up too much space, a controlled response curve (meaning there is no “peaking” in the frequency response), little or no distortion at high volume levels.

  • All things considered, the caught air inside one of these containers behaves like a safeguard or a spring against the cone of the subwoofer; it limits woofer development, so it doesn’t over-strive as far as cone movement, so every one of the notes gets delivered equitably, which brings about close exact bass.

  • Sealed car Subwoofers also have a better transient response, which can respond more quickly to bass and treble signals. This makes for a much tighter “punch” on the low frequencies while giving you a clean extended frequency range with no distortions or dips in volume levels.

  • Sealed car subwoofer boxes are a good choice for people who want to produce quality sound in their vehicle and do not need to take up much space with the enclosure itself or that it requires (speakers, amplifier wiring). They have an attractive design, and many of them are made with high-quality, durable materials.

  • If you have a space issue in your trunk, then the sealed car subwoofer box is the best choice because it is rather small in size and more compact, so you can easily adjust it where you want.

  • They’re easier to design for tighter tolerances, adding one less variable-no room or port venting requirements.

  • A sealed car subwoofer is a type of speaker with an airtight enclosure, which means that the backside of the woofer cone gets no outside air. This makes for a smoother and more natural sound because there are fewer vibrations from the backside of the woofer; this process is called timing.

  • The bass roll-off is when you hear a significant drop in volume as you increase frequency on your EQ or equalizer. That’s what happens with most speakers in general, but it’s not so prominent with a sealed car subwoofer because they don’t have any “leaks” to speak of – especially if they’re installed properly.


  • There is significantly more power required for a sealed box over a passive radiator because there is nothing external amplifying the bass waves, and it can make tight and better bass sounds.


By focusing the audio signal to be emitted from a narrow angle, sounds will seem clearer to people on the other side of the room who are not close to them. Subwoofers deliver low-frequency bass sounds and enhance overall sound quality and music experience.

A subwoofer should typically be set at 10% volume for most excellent listening ability without bothersome buzzing or distortion.

Unrelated, but don’t you think a subwoofer looks like this?

No, we are not talking about the sound-emitting device that usually stands in one corner of your room. Instead, here is an exciting trivia to know for those who want to get their facts straight: a Subwoofer refers to “a driver unit which reproduces bass.


Speakers are a significant investment for anyone who wants to enjoy high-quality audio. With so many options out there, it can be difficult to find the right one that meets your needs and budget. If you’re looking for help narrowing down your search, this beginner’s guide is exactly what you need!

We’ll discuss speaker specifications & definitions in detail – from driver displacement to recommended enclosure volume – so that you have all the knowledge necessary before making any purchase decisions.

Let’s get started!

Driver Displacement: This specification is very important to consider because it tells you how much air the speaker can move. Generally, larger drivers will have a higher displacement and are capable of moving more air with their sound waves – resulting in louder volume output for less power input than smaller speakers with lower driver displacements.

Frequency Response: This tells you how wide the speakers’ frequency range is – essentially, what frequencies are reproduced well by a speaker. Wider frequency response will produce more accurate sound, less distortion for deeper bass, and better clarity in music or movie audio.

For example, most car speakers have a very narrow frequency response that doesn’t produce a full sound range. So if you’re looking to upgrade your car audio and don’t want disappointing results, we recommend that you purchase speakers with a frequency response of at least 60Hz-20kHz so that they can produce more bass and mid-range frequencies.

Speaker drivers are measured in “sensitivity, " which is essentially how efficiently the speaker converts the electrical signal into sound. Larger drivers typically have a higher sensitivity, which can make them less efficient than smaller speakers.

Because they require more power to achieve high volume levels – even though their frequency response is wider and they’re capable of playing lower frequencies better.

There are many factors that determine how loud your speaker will play given an amount of power. For example, the speaker’s driver displacement and sensitivity make a difference – but so does your enclosure selection!

Recommended Enclosure Volume: The volume of an enclosure is Pretty simple to understand – it tells you how much air space your speakers will need to sound their best. If the recommended volume isn’t available (or if you want to alter the sound of your speakers), many other factors can be adjusted, like enclosure material, port tuning frequency & length.

Bottom & Top Depth: The depth specification for a speaker tells you how far back into the car’s interior it should be mounted so that it sounds right and is protected from damage by objects in the car.

Remember to always check the depth of your car’s interior before buying a new speaker – you can’t install speakers that are too deep!

Subwoofer Mounting Depth: For most vehicles, this specification will be listed on the back of each subwoofer box in millimeters (mm). This number tells you how far into your vehicle’s trunk you can install the subwoofer and still have enough room for the sound to properly resonate.

For example, if your mounting depth is 125mm (or about four inches), then you’ll need a minimum of 500mm (20”) behind any objects to avoid damping the bass response or having it bounce around inside the enclosure.

Remember that this specification is for your subwoofer’s mounting depth – not the size of its woofers! So if you have a shallow trunk, don’t worry – there are many smaller subwoofers available with small footprints that will fit in almost any car.

And, if you’re looking to increase the bass response in your car and want a harder-hitting system, pair it with an aftermarket amplifier. It can provide more power for louder sound output!

That’s all there is to find out how deep of a subwoofer or speaker enclosure will fit into your vehicle – thanks for reading!

Sealed Subwoofers sound better they can reproduce a frequency response that is much more linear and accurate.

A sealed sub is a type of speaker cabinet designed to improve efficiency by sealing the interior space. The main goal of this design is to control the back wave caused by the driver inside, thus reducing distortion from both cone breakup and port turbulence.

In general, these types of speakers have a smooth boundary-coupling with less power leakage across their passive components – they typically have tighter coupling between speaker section and amplifier, so there’s less electrical interaction with the drivers.

This does affect performance negatively because it lowers total cone area for low frequencies as well as deprives an additional surface that could provide greater bass output within a small box, but it has an advantage over port-loaded speakers in that the impedance stays high (so long as you don’t use ports) and thus, most of your power is delivered to the speaker.

This is good because it keeps the amp’s frequency reproduction more linear and accurate at all frequencies. It also makes for a much stronger coupling between amplifier and speaker, so you can get away with a real-world amplifier that’s much more powerful than the RMS wattage would suggest.


We have described our team research for Choosing the right box: Ported vs Sealed subwoofer, what’s better for you. -What is a sealed car subwoofer box, and how does it work? The advantages of using a sealed enclosure are that it will produce louder bass than other enclosures due to less air movement within the enclosure, which can lead to distortion at higher volumes.

It also has tighter sound quality because there is no back pressure from outside sources like wind or exhaust noise entering the speaker system. The disadvantage of this type of setup is that it takes more power to generate high output levels; however, if your main concern is volume, then this may be worth considering as an option for your audio system.

But my own experience is, it depends on your own choice, what are your requirements as we discussed. We have tried to guide you completely, but please drop a kind comment here if you feel anything more to describe.

Our humble request is only one; please share this article to help your friends and family members.


1. What sounds better a ported box or a sealed box?

Answer: A sealed box.

The air in the sealed box will be compressed during playback and can maintain high noise levels. The ported box allows exhaust of some pressure waves, lowering sound output as well as creating a higher risk of stuffiness due to the closed environment.

2. Can you turn a sealed box into a ported box?

Answer: You can’t turn an unsealed box into a ported box, but you can turn a sealed box into a vented one.

A sealed sound enclosure does not require any vents or ports, and it’s the most basic type of speaker enclosure to manufacture because there are no openings on the front panel.

Inserting a vent or port will allow the sound waves (i.e., air) to escape from the back of the speaker cabinet more easily, decreasing pressure inside and increasing pressure outside (see P = ρ x V).

This lower internal pressure, in turn, makes it easier for our eardrums to vibrate with less interference from this resistance. Low internal pressure is also needed for low-frequency sounds so that the speaker cabinet won’t be too thick and heavy.

3. How much louder is ported than sealed?

Answer: Ported speakers are louder due to the additional space and surface area of the port.

Conversely, sealed speakers produce tighter bass and a more accurate sound because nothing interrupts the speaker cone’s airflow to the listener.

Nest 12dB on average. Generally speaking, ported cabinets will give less air displacement efficiency than sealed cabinets (because they’re trying to push a lot of air through a small hole). So they have less output for input power than their sealed counterparts.

4. Does a sealed or ported box hit harder?

Answer: Ported.

Ported boxes have a smoother off-axis response, while sealed systems have two standing waves that cancel and provide a more dynamic sound. Bass waves travel in a straight line, so ported enclosures produce more bass in specific places where you might put your ear to hear it.

5. What happens if ported box is too small?

Answer: It could hinder the sound system’s performance dramatically.

If the ported speakers are too small, they do not have enough space to produce a louder sound. The resonation waves will be compressed, causing distortion and unclear volume levels.

6. Does the shape of a sealed subwoofer box matter?

Answer: It does. The size and shape can affect sound performance.

A sealed box is a cabinet that bounces sound waves back to you after they’ve bounced off the front wall of the box. This bouncing creates reverberation (or “reverb”), which sounds best when it’s dense, defined, full-bodied and long in decay time.

These qualities are achieved easier by minimizing reflections, so a round or oval volume with more surface area reflecting less evenly will produce better sounding reverb than an elongated volume with only one short end reflecting poorly.

7. How to make a sealed box louder?

I wish I knew why popcorn has a high volume when you shake it in the sealed box? I also think there is some magic in that cooking process.

Did you try to make one yourself? Good luck. Well, I wouldn’t take silence for granted. Suppose your speaker/mini-speaker doesn’t perform well enough on its own.

In that case, you can always get creative and improvise with other sound sources, like using objects (rubber bands?) on a side table near your speaker to create a percussive beat that can blend nicely with the music.

I recommend using soft materials like napkins or tissue paper rather than Metallica because who knows what will happen if they touch the speakers!

Another suggestion is modifying the box to make the sound less hollow and adding some “modesty” panels around the speaker. It’s always good to have your box double as a carry-case!

8. What gives more bass ported or sealed?

If your ear is tuned for a sealed speaker, it’s best to use a sealed system. You may notice that the bass is stronger, but the overall sound is less transparent. However, if you like bass and prefer ported speakers, a ported system is better for you.

You can get bassier response from a ported system with less distortion and breakup. But porting a system makes it much more sensitive to room reflections and positioning.
