1️⃣ MTX Audio Terminator Series TNE212D


  • Amazing bass response.
  • Very loud and clear.
  • Super affordable.
  • Value for money.


  • The amplifier is prone to overheating.
  • Might distort at very loud volumes.

MTX is a pretty well-known car subwoofer brand, and the TNE212D subwoofer box is definitely a value for money product. I’m actually surprised with the audio quality in this price range.

Build Quality

It is a sealed pre-mounted dual enclosure, that comes with 12-inch dual subwoofers, and a 5/8 inch MDF construction, with the MTX logo on the dust cap. It would fit very well in my red Nissan hatchback, and would probably blow the roof off given its 1200 Watt total power. 

  • The 37-150 Hz frequency range is more than enough to enjoy bass-heavy music.
  • The enclosure has a 2-inch aluminum foil and a standard Polypropylene Cone.
  • On top of that, you get a 1-year warranty on the subwoofers.
  • The build is solid, durable, and premium-looking.

Sound Performance

The bass is clean and crisp and the overall frequency range is appreciable. The 800W peak and 400W RMS power rating manage to provide loud volumes with amazing clarity, but are subject to a little distortion and also, might rattle your car a bit too much.

But who’s complaining?

After all, I’d want a subwoofer to really push its limits. The TNE212D does just that. Rest assured, the response is top-notch for the money you invest!

Connectivity Features

A standard wiring kit is required to hook up the subwoofer with the car’s battery.

Ease of Setup

The enclosure already has speakers installed, so there’s a very little hassle in setup.

2️⃣ BBox E12DV Dual 12-inch Vented Carpeted Enclosure


  • Deep bass and high-quality low-frequency response.
  • Premium quality build and design.
  • Easy to set up.


  • Struggles in the bass at loud volumes.
  • Not for heavy and hardcore music.

The BBox E12DV is a compact, sealed enclosure perfect for fitting in a tight area. This enclosure is a high-quality offering from the hands of a company with 25 years of experience in box-building – Atrend.

Build Quality

Atrend Bbox E12DSV Pro-Series (1)
Dev Thakkar/ Swing Vertigo

This 12-inch sealed enclosure’s panels feature the Atrend’s signature Miter and Dado construction, which adds extra reinforcement and structural integrity. Its design and quality construction guarantee that all elements are airtight and precisely fitted, resulting in a rattle-free atmosphere.

I would say the enclosure is a premium, super high-quality designed box. Atrend promises a build of 1-inch MDF front baffle, 3/4 inch MDF construction, Atrend’s super ‘trick’ glue, and premium charcoal carpet, but many have experienced a rather quick ripping of the carpet and inner seams of the box seem to be very cheap.

Sound Performance

This subwoofer box delivers the kind of deep bass output and low-frequency reproduction you’d expect from a high-end subwoofer.

I was actually curious as to how the enclosure performs at loud volumes given its compact build, and it did not disappoint. It can go loud without actually giving you the annoying vibrations, but also loses a tad bit of the deep-ended bass, although it is acceptable.

All in all, a very good quality subwoofer in terms of bass response. But if you’re looking for a box to smash your hardcore bass-heavy music, I’m afraid this won’t be the best choice.

Connectivity Features

A standard wiring kit is required to hook up the subwoofer box with the car’s battery.

Ease of Setup

With external dimensions of 30 x 17 x 12 inches, the box is easy to set up in a vehicle since it can fit snugly in tight spaces in most cars. The subwoofer installation is a breeze, with ample headroom for the subwoofer and a very accessible connectivity port.

3️⃣ Atrend Bbox E12DSV Pro-Series 12” Dual Vented Subwoofer Enclosure


  • Exceptional bass quality.
  • Premium build.
  • Perfect for cars with bigger boot space.
  • Loud and boomy.


  • Bigger than mentioned in the product description.
  • Connecting is a hassle.

The E12DSV Dual Vented enclosure is a step above the single vented at #2. It offers similar quality but at an added advantage.

Build Quality

With almost the same build and design as the single vented enclosure, the E12DSV 12-inch Dual Vented pro-tuned enclosure comes with two vents instead of one. This provides a much louder, richer, and amped-up bass as compared to the previous model.

The box can house even the most powerful of subwoofers without endangering audio quality.

Sound Performance

The dual box design does play its part in delivering an optimum bass response, even at higher volumes without the fear of distortion.

Even though the system offers a boomy sound, it can lack in providing accurate bass reproduction in heavier songs. But it’s not noticeable unless you’re a dedicated audiophile that cares about the tiniest of details.

Connectivity Features

best subwoofer box for deep bass

It has standard connectivity procedures. The enclosure can also double up as a home theater subwoofer but requires additional wiring that doesn’t come in the box.

Ease of Setup

The terminals for the wiring are a little annoying to reach and connect properly, but otherwise, the setup is straightforward. The box seems quite big even though its dimensions are the same as the E12DV Dual Vented enclosure mentioned above. Advisable for cars with bigger boot space.

4️⃣ Q Power QBOMB12VL Side Ported 12-inch Subwoofer Enclosure


  • Value for money.
  • Exceptionally loud for its size.
  • Very compact and easy to install.


  • Decent build quality.
  • Looks bigger in pictures, but can hardly fit a 12.2-inch subwoofer.
  • Can’t handle louder volumes for long.

QPower was relatively unknown among most car audio enthusiasts, so the success of the QBOMB12VL 12-inch side ported subwoofer enclosure is truly impressive.

Build Quality

Dev Thakkar/ Swing Vertigo

At first, I didn’t think the enclosure could even house my Alpine SWT-12S4 12-inch subwoofer with a peak power of a 1000W in it, but it barely did even though it’s a 12-inch enclosure. The overall build quality is decent, with a 3/4 inch MDF construction.

Weighing at just a mere 25 pounds, it is a compact, sleek-looking, durable box.

Sound Performance

The box is LOUD. I mean, incredibly loud. For a small ported enclosure, it definitely takes the cake for efficiency as well. Small size, powerful sound is the best way to describe it.

  • The enclosure can handle the loudest volumes without damping the bass and provides the maximum slam that can come from a compact enclosure.
  • Sure my subwoofer may be a little strong for it, but I think the enclosure was able to handle it at around 600W peak and just a few clicks away from the maximum volume.
  • Although there are instances where there is distortion or dampening in particular genres like heavy-hitting electronic dance music, after prolonged usage.

Connectivity Features

There are screw-down terminal cups for connectivity, allowing for a stronger wired connection.

Ease of Setup

It’s a pretty small box at 22 x 15 x 13.5 inches, and could barely fit a 12.2-inch subwoofer inside it. But it’s incredibly easy to set up, and easy to install in any car.

5️⃣ Skar Audio SK1X12V Single 12’’ Ported Universal Fit


  • High-quality sound reproduction, with great bass.
  • Premium quality build and design.
  • Easy to set up. Plug-and-play.
  • Super loud.


  • It is a little bit costly.
  • Lacks in producing the deep low-end bass.

I’ve seen quite a few subwoofer boxes for this article, but the Skar Audio SK1X12V is a very powerful subwoofer, a cut above the rest. Probably the one you must consider above all others.

Build Quality

The enclosure is minimal, compact, and has a sleek design. The box sports a premium quality black carpet outer with the inside walls of the enclosure lined with a poly-fill mat to enhance sound reproduction.

The box is high-quality, with a single chamber, and a universal 12-inch fit. With its tuning frequency set to 36 Hz, the ported enclosure has a standard ⅝-inch front baffle MDF with a kerf (rounded) port design.

Needless to say, it is top-quality.

Sound Performance

Good Audio Quality

Being a ported enclosure, loudness is absolutely no issue. I mean it when I say this enclosure gives out a massive bass response but also a smooth texture to it.

You would hear the accuracy in the bass notes but also experience the slamming thumps of bass when listening to loud volumes.

The lower bass frequencies around 20-35 Hz aren’t as prominent as they should be, but given it still is a ported box, it is more than adequate.

I’m sure you’d have people hearing you from about a couple of blocks away while you blast those tunes from your car.

Connectivity Features

Consists of high-grade push terminals with internal speaker lead ready for installation.

Ease of Setup

Super easy to set up with your car battery. The subwoofer installation is fairly simple and the rounded 11-inch front hole is more than enough to fit any 12-inch woofer. It is a small box, and will easily fit inside any vehicle.

👉 Why Buy A Subwoofer Box?

Subwoofers by design require an enclosure to balance the front and rear frequencies when they’re produced by the sub.

If used without an enclosure, the frequencies that would usually be bounced back into the box are sent into the air freely and will likely reduce the sound qualities, or cancel out their effects.

Using a subwoofer without an enclosure box will result in a weak and drowned-out sound.

A subwoofer box is then set up to allow the low-frequency sound signals to follow a path of physical laws to provide an optimum bass response expected from the subwoofer.

🔰 Types of Subwoofer Boxes


  • 1. Sealed

    A sealed box is completely sealed airtight which provides a precise and tight bass. It is best for enjoying music that requires a deep, clear bass to be able to fully appreciate it. Such as the deep bass sound of a cello and trombone that might play in orchestral or jazz music.
  • 2. Ported

    A ported enclosure has ‘ports’ or vents located at the rear or bottom, which allow for air to pass through. This results in greater overall output than a sealed enclosure. It is the perfect type of enclosure to jam to bass-heavy and loud music in your car.
  • 3. Bandpass

    A mix of sealed and ported enclosures, the bandpass subwoofer box is made up of a single enclosure with a divider inside that divides the space into two chambers. The divider also serves as a woofer mounting surface. One chamber is sealed, while the other is open. They are capable enough to give out booming sounds and rattling bass.
  • Free-Air

    Also called an “infinite baffle” system, a free air subwoofer is a specially built subwoofer that does not require enclosure installation. They’re installed in the trunk space of the car or even against the rear seatback, which acts as an enclosure. There is a flat response from this setup and offers a standard but smooth bass sound.

📖 The Practical Buying Guide For Subwoofer Box Design in 2022

Buyer's Guide

Once you have a subwoofer, you’ll need the most optimum enclosure to house it in.

As there are different types of subwoofer enclosures available, let me show you how to determine which one is perfect for you.

Size of the subwoofer

First off, you should consider the subwoofer size.

If you have a small subwoofer, say an 8-inch subwoofer, it wouldn’t make sense to put it in a larger enclosure. Doing that will significantly dampen the bass and give out a very grubby sound.

Or even the other way round, a bigger subwoofer won’t fit in a smaller box.

So, buy a subwoofer box according to the size of your subwoofer.

What kind of sound are you looking for?

  • Are you an audiophile that listens to bass-heavy music from the likes of Dubstep lord Skrillex and metal bands like Led Zeppelin?
  • Or someone with a deep appreciation of cinematic soundscapes full of rich, lush tones with a smooth bass end?
  • Or do you just want a general all-purpose performance sound so you can listen to your music in the best way possible?

Choose a design that bodes well with your wants.

Where will you be using your subwoofer?

best subwoofer box for deep bass

If you’re going to install your subwoofer with a home theater, you also need to consider the specifications and sound frequency response of the main speakers.

There should be no phase issues while using, so choosing the proper subwoofer box design is paramount in this case.

If your subwoofer is going in your car stereo system, you would want to consider a compact, space-efficient design like a free-air subwoofer box.

Understand your space

A big subwoofer box in a small room will seem off and take up an unusual amount of space. Additionally, such a powerful sound would be too much for the room to bear.

A smaller enclosure in a big room won’t do your investment justice.

While installing in your vehicle, you need to consider the placement as well as the space you’re willing to give away for the subwoofer enclosure. While the most common location would be in the trunk, there are enclosures specifically for vehicles as well – such as under-seat designs or against the rear seats.

Type of Subwoofer Box

Types Of Subwoofer

As mentioned earlier, you’ll have to choose between a wide array of enclosure designs. Each has its pros and cons.

  • A sealed subwoofer box will give a tight, punchy bass response.
  • A ported subwoofer box will be able to give a deep, monstrous sound.
  • Bandpass enclosures are more or less like a ported box but give you the best of both worlds – sealed and ported.
  • A free-air box is suitable for installing in a car.

In terms of size of the enclosure, the bandpass boxes are the biggest, followed by ported boxes.

If you’re looking for compactness, a sealed subwoofer box is an excellent choice. 

Also, consider the power and sensitivity rating of the subwoofer.
If the subwoofer box enhances the bass but the subwoofer isn’t designed to handle any extra power or sound response, it can cause an unnecessary spike in frequencies and may damage the speaker.

🧮 Can you make a Subwoofer Box at home?

It is entirely possible to make your own Subwoofer Box at home. The construction is easy, provided you are aware of the specifics and requirements for your DIY speaker box.

More on this below.

🎯 What are the points to note for DIY Subwoofer Box Build?

Important Points
Important Points


Make sure the size of the box you design is optimal for your subwoofer. Keep in mind that you have to leave space for the motion of the woofer coil, just enough that it has enough wiggle room to prevent overheating. Build the woofer box according to the size of your room. Oh, and also so that it looks good!


While wood is the preferred choice for the box, the materials you need depend on the type of subwoofer box and shape as well.

  • If you’re going for a ported box, you’ll need material for the ports.
  • If it is cylindrical in shape, you’ll need foam and fabric.
  • You will also need some damping material for acoustic insulation inside the enclosure.
  • You can also use MDF for the box or metal for cylinders.


You’ll need an amplifier to power the subwoofer, speaker terminals, and the main woofer driver. Apart from these, building materials like electric drills, screws, glue, and cutting tools, are needed.

Type of Box:

Sealed, ported, free-air, or bandpass? You should choose a type of enclosure according to your needs. If you’re making a ported box, consider using the Sonosub program to tune your woofer.

I would suggest that before you start building, figure out what kind of bass response you need to match with your main speakers. Do you need more punchy, precise bass? Or a loud, wall-shaking bass? Then move on to the type of box, decide on a size according to your room, and get the components together.

What is the difference between a sealed and ported Subwoofer Box?

Sealed vs Ported
Sealed vs Ported

A sealed subwoofer box design will give out a more tight, clear-cut bass that is very smooth and deep, with a hard-hitting quality to it.

A ported subwoofer box design will pump out more volume and has a boomy, more amped-up bass response. A ported box requires less power but delivers a thunderous bass at loud volumes.

Sealed Subwoofer Box

  • Design – The subwoofer is enclosed in a sealed box either from the front or the back, also called an acoustic suspension enclosure. The air inside the box behaves like a spring that limits the movement of the cone of the woofer, acting like a sponge or shock absorber – resulting in punchier, accurate sound. They are the easiest to design and implement.
  • Power – A sealed enclosure provides excellent power handling, but requires more power to give a louder sound.
  • Size – Though sealed enclosed subwoofers vary in size, they’re usually built in smaller dimensions. If a sealed box is larger than it has to be, the cone movement won’t be restricted by the air inside which might cause damage to the suspension of the speaker.
  • Bass Roll-Off – The bass roll-off is basically the removal of low frequencies that the speaker has a hard time producing, or those frequencies that are unnecessarily playing. If the roll-off isn’t set up properly, the quality of sound can be affected and the audio might come out all muddy. A sealed box usually has a roll-off at 12dB/octave, resulting in a more consistent and smooth roll-off.

Ported Subwoofer Box

  • Design – A ported, or a bass reflex enclosure, contains one or more ‘ports’ or vents, which allow the rear sound wave to escape and couple with the front wave generating a louder sound output. They are more difficult to construct and require more air space than sealed enclosures. If built incorrectly, it can lead to woofer damage.
  • Power – Comparatively, a ported box is very power efficient, giving a good amount of bass and volume in limited power wattage.
  • Size – Most ported subwoofer boxes are better off in larger enclosures. They can be tuned to lower frequencies and are less likely to unload. Though you will get a loud and deeper bass, it will not be as tight and smooth as compared to a sealed box.
  • Bass Roll-Off – A ported box has a bass-roll off at 24dB/octave, twice as high and fast as a sealed box. Because the rear sound wave and the front sound wave together give out louder bass responses.

A sealed vs. ported box is also a vital consideration in determining the standard of sound you may get from your system.
Sealed vs. ported enclosures are created by way of what we call audial suspension vs. bass-reflex layouts.

💡 FAQs


Q1. What size subwoofer has the deepest bass?

The bigger the subwoofer, the more capable it is of producing deeper, heavier bass. A 15-inch subwoofer box reproduces the deepest bass owing to its giant size.

Q2. How do I make my subs hit the hardest?

1. You can add more mass to the subwoofer cone, making it heavier. It will cause a reduction in resonant frequencies, driving the subwoofer to play lower, deeper bass.
2. By upgrading your subwoofer box with a newer enclosure, changing voice coils, and adding phase shifters or filters.
3. Positioning your subwoofer box in a corner of the room, and asymmetrically from two walls will result in a much louder output.
4. Fine-tune the volume of the subs in accordance with your main speakers. A properly adjusted overlap will seemingly make your subs hit harder than the default settings.

Q3. What happens if a subwoofer box is too small?

A small subwoofer box might result in a reduced power level and a bad reproduction of low frequencies. The bass won’t hit as hard and will sound thin.

Q4. Does inverting a sub make it louder?

As a general rule of thumb, inverting your subwoofers does not make their output louder. Although, inverting reduces the heating generated inside the box and can solve space issues. But by no means will inverting a sub make it any louder.

Q5. What Hz is best for bass?

60-250 Hz is the best range of frequencies for bass going by the audio spectrum and the industry standard. For sub-bass, anywhere between 30 and 40 Hz is best.
