Top 7 Best Subwoofer Box Port (100% Tried & Tested!)

Subwoofers are an essential component of home theater systems. They deliver powerful bass sound that can make or break a cinematic experience.

And when it comes to building your own home theater system, adding a subwoofer is one of the easier and least expensive things to do. But there are a few things you should know about what goes into a box port.

The subwoofer box port is an opening in the subwoofer that directs air in and out. The darker and better sealed the box port is, the more air it will block.

This can range from a comfortable 25-50% to almost zero, which will create a louder and tighter bass response.

In our home theater lab, we test boxes ports of subwoofers and other speakers. We measure them using a homemade device called the Box Pressure Test.

This test measures the overall pressure and volume of air that escapes the box port. We also record the subwoofer’s enclosure resonance frequency, which helps determine how tightly sealed the box is.

In our testing, we found the best subwoofer box port. This subwoofer has a sealed box port that blocks 38% of the air that escapes, allowing it to maintain a loud, powerful bass response. This is due in part to the subwoofer’s thick, black foam that surrounds the box port.

3. Uxcell 2Pcs 65mm x 74mm Speaker Port Tube Subwoofer:

The uxcell port tube is essentially 2 ports in one, making it far easier to build bookshelf speakers that resemble studio monitors.

The thick-wall design and fixed balance point on the sides ensure that bass resonance is suppressed, and the perforated metal grille improves the low-frequency performance. The package includes an allen key for tightening down the tube at the desired angle.

The heavy metal mounting points on the bottom of the speaker have a jack mount and screw thread, so you can choose between fixing the port box to the speaker via speaker stands or screwing it to a wall.

The vented port is located at an angle, giving the ports a greater bass response than a port placed at the bottom.

The port can also be used as part of a larger design if you want to improve the low-frequency performance of a taller speaker, especially if you don’t want a hole in your wall.

The step-down at the port is that bit more noticeable, but the sound quality is good, if slightly unspectacular. The

5. Uxcell 2Pcs 75mm x 89mm Speaker Port Tube Subwoofer:

The uxcell 3.5mm speaker tube is a handy, nicely designed wedge-shaped tube that can be attached to the back of your speaker for a more pleasing effect and sound. It looks nice, is functional, and will complement any aesthetic.

The tube measures 155mm long and 53mm wide at the top, tapering to 43mm wide at the opposing end. However, it’s 75mm high and 89mm long and, as the name indicates, is threaded and is compatible with most 3.5mm audio connectors.

It’s a softer plastic, so won’t scratch or damage your speaker, and high-quality finish. It has a 90° bend at the top, to prevent it from sliding around, and is hollow and perforated, with a handy plastic cover that doubles as the speaker mount.

Fitting is simple:

Simply screw it to the mounting holes of your speaker, pushing the locking nut to hold it securely in place. As long as you tighten evenly, and take care not to overtighten, it should stay securely in place.

These are good quality, solid speaker ports that won’t have that annoying rattle you hear from other, cheaper speaker port tubes. They should last quite a few years, and are built well enough that they should last a long time and withstand a lot of abuse.

Solid seal against moisture and dust:

The polycarbonate seal provides a solid seal against moisture and dust, ensuring that your speakers are kept clean and working like new. That seal also makes this a useful speaker port tube, allowing you to deliver bass directly to your subwoofer.

Overzealous bass from a PC or other home theatre system can drown out dialogue, and these reliable ports can minimise that problem.

While they’re not as compressed or precise as a dedicated subwoofer, they should allow you to enjoy those occasional explosions on your favourite games.

The sound they deliver is a little more coloured, but less bass heavy than a box sub, which is possibly a more professional look. It’s a decent bass tube that will work with most headphones, or with a smartphone.

Built to last:

It looks good, and is built to last. The inclusion of a plastic mount sleeve is a handy touch, making this a serious investment for plastic tube fans. If you’re looking for a high quality speaker tube that can be attached to most 3.5mm connectors, and works with most devices, this is a decent choice.



6. Pastlla 7″x3″ Speaker Port Tubes Plastic ABS Speaker Cabinet Port Tube:

The new Pastlla line is, as the name suggests, much more affordable than the TRB series it replaces, which makes these attractive.

Pastlla’s flagship (and only) model, the 6T, is a tower speaker that can pack a serious punch, while the 3T is a 3.5in three-way floorstander that’s built to sound good no matter what position it’s placed in.

Pastlla’s new 7T bass reflex tower speaker, meanwhile, offers a surprising amount of punch for a five-driver model that costs just 1000W. There’s actually a pair of 7T speakers, which renders the old 6T redundant.

Measuring 1.9m tall and 1.8m wide, this is a very large tower speaker, but what sets it apart is that the bass reflex port is at the rear rather than the front.

A few speakers have bass reflex ports at the rear, and Pastlla’s new 7T isn’t the first I’ve heard with a port here, but what sets it apart is the port has a hole drilled into it.

This effectively means the port tube is missing the part of the speaker cone where the bass reflex port is located. This effectively means the port tube is missing the part of the speaker cone where the bass reflex port is located.

This difference has two distinct effects.

First, it frees up space at the back of the speaker that can be used in other clever ways. Second, the way the port is tuned changes how the bass is delivered. In the past, this setup has always meant a huge muddiness to the bass, and while the 7T is more than capable of rousing the biggest of crowds, it does so with a gritty, weighty feel.

It’s weighty in the good way, emphasising the bass’ weight and impact rather than pushing it out and away from the listener. The treble isn’t burnished to a high sheen, but does have a more even response than you might expect from a speaker of this size.

It just depends on what you want from your music: if you want top-end sparkle with razor-sharp detail and floor-rattling bass, look elsewhere.

But if you want a well-rounded, engaging performance that pairs perfectly with a mid-range, punchy subwoofer, then Pastlla’s new 7T bass reflex tower speaker is worth a look.



7. Uxcell 100mm x 160mm Speaker Port Tube Subwoofer:

We purchased this port tube expecting it to mount our 10″ speaker in a vented box, but it provided very little bass response.

We’ve since discovered that, because it has no mounting hole and a flared tube end, this port tube is designed to be used with a flat top speaker, not a box.

Our 10″ speaker has a perfect mounting hole for a 6″ speaker when viewed from the front, but the port tube allows only a speaker with a 4″ diameter mounting hole.

It would have been helpful if the listing had said flat top speaker only or box speaker rather than speaker port tube.

The flared end on the port tube means that the speaker won’t fit easily into the front of the box, either, so it won’t allow the speaker to sit flush with the box.

It also won’t allow the speaker to sit too far back, so the box won’t be as efficient as it could be. In our tests, our vented box without the port tube was more efficient and produced a more responsive sound than the vented box with the uxcell port tube.

  • Standard Mount Hole
  • Suitable for 5-6″ Speaker

How To Choose Best Subwoofer Box Port?

A subwoofer box port is an essential component of any subwoofer. It’s what allows air to flow in and out of the subwoofer in order to keep it cool.

Most subwoofers use what is called a ported design, which means air is blown in through one port and out through another.

However, some subwoofers use what is called a sealed design, which means the subwoofer is completely sealed off and the air is contained inside.

In this blog post, we will explore the differences between ported and sealed subwoofers and show you which is best for you.

1. Determine the size of your subwoofer:

The first thing to consider is the best subwoofer box port size. A subwoofer box port size is determined by the size of the subwoofer.

2. Look at different types of ports to find the best one for your subwoofer box:

The type of port that you’ll use in your subwoofer box will depend on the size of it. The port size will be determined by the size of the subwoofer and the enclosure.

Smaller enclosures typically utilize a 0.5 inch diameter port. A larger enclosure will use a 4 inch port. It’s up to you, and your enclosure, to choose the port size.

You can also use larger ports, but you’ll need to account for additional space. Areas that have larger ports require more space than areas that are smaller.

3. There are three main types of ports you can choose from: flared, square, and round.

There are three main types of ports you can choose from: flared, square, and round. A flared port is shaped similar to a trumpet, and this gives the sound more bass and resonance.

A square port is shaped like a rectangle and have more of a flat, even tone. Round ports have a circular design and have less bass and resonance.

4. Flared ports are the most popular type of port and are usually found on subwoofer boxes.

Flared ports are the most popular type of port and are usually found on subwoofer boxes. A port is a hole that faces the inside of the speaker cabinet, which, in turn, faces the outside of the box.

The cabinet is completely sealed, but the port is flared, allowing air to travel in and out of the box.

A flared port on the subwoofer box provides a way for the woofer to move air in and out of the cabinet. By adding air, the bass sounds produced by the woofer are amplified. The port also prevents air from bypassing the speaker.

A round port is the next type of port and is less common than flared ports. Round ports are circular in shape and are usually found in small enclosures. Round ports are more effective in small spaces than flared ports.

5. Square ports are less common than flared ports:

Best subwoofer box port in terms of efficiency and performance.

Square ports are less common than flared ports but can be more efficient because they have less air turbulence.

6. Round ports are the least common type of port:

A subwoofer box port is a hole or other opening in the bottom of a subwoofer, which allows air to pass through.

A port’s design determines its efficiency. Ports can be round, square, or flared; round ports are the least common type of port and are not as efficient as flared or square ports.

7. Best type of port for your subwoofer box depends on your subwoofer and the type of music you listen to.

The best type of port for your subwoofer box depends on a few things. First, the type of subwoofer that you have will determine the port.

Your subwoofer may have a proprietary port. Or, it may have another type of port called a passive radiator.

The type of music you listen to will also determine what type of port you want. If you listen to mostly pop or rock music, then you may want a closed port. If you listen to other genres of music, then you may want an open port.


Ported and sealed subwoofers each have their advantages and disadvantages. Ported subwoofers are more flexible and can be placed closer to a wall, but they tend to be noisier and use more power.

Sealed subwoofers maintain a consistent volume and produce less noise, but they are typically more expensive.

Sealed subwoofers are often better for situations where space is limited. We hope that this post has helped you determine which type of subwoofer is right for you.
