What is Sealed Enclosure?

A classic box design, sealed enclosure, is also known as acoustic-suspension or air-suspension enclosure.

It is an airtight enclosure that houses a subwoofer.

You need an ample wattage amplifier for optimum performance since it requires more power.

This enclosure adopts by many car audios companies and homes.

What is Sealed Enclosure for?

A sealed enclosure is suitable for music that requires accurate, tight bass.

How Does Sealed Enclosure Work?

The woofer in sealed enclosures is controlled by trapped air volumes in the enclosure.

It acts as a spring.

The woofer will pull the air with it as it is outward moving.

Therefore, the air pressure is reduced inside the box.

Also, inside the box, the air is compressed as it moves inward.

Moreover, the atmosphere’s barometric pressure is equal to the air pressure inside the box.

It acts as a force that controls the movement of the speaker.

If the speaker moves outward or inward, the greater pressure is produced by the sealed enclosure’s air-spring in the other direction.

Why I Need a Sealed Enclosure?

There are several reasons why you need a sealed enclosure.

Here are a few reasons:

• Very Smooth Roll-Off

A sealed enclosure is similar to other enclosures, such as bass-reflex.

It has a 24 DB/octave steep roll-off.

• It has the excellent transient response

Meaning, your speaker is very vibrant.

It can play sudden sound waves, such as drums.

The speaker should start and stop properly for better transient response.

The spring that acts as a suspension also helps to achieve a better transient.

• Very easy construction

Make sure that the box is all set and doesn’t leak air.

Its internal volume needs to calculate beforehand.

Each speaker has no particular volume.

The only thing to do is to understand your taste in sound and what you’re using for it.

After that, you can calculate the box volume.

What is the Primary Advantage of Sealed Enclosure?

There are several advantages of sealed enclosure for your application, including:

• Simple to build
• Small
• Good transient response
• Excellent low-frequency control and extension

Moreover, a sealed enclosure is more compact compared to a ported enclosure.

So they will suit I

What is the Disadvantage of Sealed Enclosure?

The sealed enclosure may have low efficiency.

You need a 200W amplifier so that they are the same as brass-reflex.

It drives a particular woofer in a sealed enclosure with the same output.

The sealed enclosure will sound deep and tight, but not loud.

What Are the Best Speakers for Sealed Enclosure?

When constructing a sealed enclosure, you need to pick the exact woofer.

It is very easy to do.

The right woofers include long voice coils, high cone mass, and low free air resonance.

They will work well in sealed enclosures.

Is Ported Enclosure Better Than Sealed Enclosure?

The sealed enclosure is known as an acoustic suspension enclosure while the ported enclosure is a bass-reflex enclosure.

The ported enclosures are usually used for more output is available from the same power amplifier.

They are better than sealed enclosures because the ported enclosure is more efficient.

Ported enclosures have more total output compared to sealed enclosures.

Meaning, they can play louder.

How Much Louder is Sealed Enclosure Than Ported Enclosure?

The best bass you will get depends on the subwoofer enclosure you use.

Here are the types of subwoofer box that gives impact on bass sound:

Sealed Enclosure:

• Smaller box size
• More accurate, tighter box
• Requires more power for blasting bass

Ported Enclosure:

• Larger box size
• Less accurate, the bass is boomier and louder
• Doesn’t need much power, more efficient

What Will Happen If My Sealed Enclosure is Too Big?

If your sealed enclosure is too big, normally the air pressure will be lost inside.

As a result, it slows down the woofer and reproduces a lower frequency.

After a particular point, a sealed enclosure will be sounded like trash and sloppy uncontrolled.

However, it all depends on your driver’s specs.

Several speakers are fitted for a sealed enclosure, some are for the vented enclosure, and in between.

You only have to do is to look at how enclosures are designed, determined, and built.

Can I Port a Sealed Enclosure?

No, you can’t convert a sealed into a ported.

It would be best to buy a new ported and build on more sealed subs.

You only have to do is to plug a port on ported subs to create a seal.

However, it is not recommended by most manufacturers.

Can a Sealed Enclosure Be Loud?

A sealed enclosure isn’t typically loud than a ported enclosure.

However, it still improves the listening experience by supplying kick drums.

This kick drum is represented as a specified low-frequency passage.

Thus, the bass can be felt in the vehicles’ seats and your chest as if you are in the front row at the concert.

How Does Sealed Enclosure Produce Louder Sound?

There is a technique to improve the sound of your sealed enclosure.

You can fill a polyfill into your enclosure.

The airflow will slow down by filling polyfill within the subwoofer.

As a result, it will provide a cleaner and tighter bass production.

Can I Add Ports in My Sealed Enclosure?

You should not drill holes or attempt to add a port in your box.

Each port size is balanced with a cabinet volume, driver parameter, port width, port length, and amplifier set.

But if they fit for a ported enclosure and you know the driver parameters, then you can create a vented box for different tuning points.

Does a Sealed Enclosure Handle More Power?

A sealed enclosure increases more and more XMAX for a given power amount.

Xmax does not decrease if you go lower until you reach the freq.

NOTE: XMAX is the distance of the subwoofer voice coil that can be moved in a straightforward direction without quitting the magnetic zone.

How to Calculate the Volume of My Sealed Enclosure?

To calculate the volume of your sealed enclosure, you can measure the depth, width, and height in inches.

Then, you can multiply them all together and divide them by 1728.

If you calculate the internal measurement of your box, such as:

• 12 inches deep, 18 inches wide, and 6 inches high

Then the volume of your sealed enclosure is 1296/1728=. 75 ft^3.

Do Sealed Enclosures Play Lower?

Most of the sealed enclosures are designed for flatter frequency response around wider ranges of frequency.

It can provide lower frequency to your box and is not as loud.

Does Sealed Enclosure Need Polyfill?

Polyfill is a polyester fiberfill material used for enclosures.

However, a polyfill is not suitable for every application.

But if your enclosure is bigger than the manufacturer’s suggestion, the polyfill is not necessary.

It could give a negative impact on the sound.
