A ported sub box is a type of subwoofer enclosure that uses a port to increase the low-frequency output of the subwoofer. The port is a hole in the side of the enclosure that allows air to flow in and out of the enclosure. This air movement helps to create a low-frequency resonance in the enclosure, which results in increased bass output.

Ported sub boxes are often used in car audio systems because they can provide more bass than sealed sub boxes. However, they can also be used in home audio systems.

In this tutorial, we will show you how to port a sub box with PVC. We will provide step-by-step instructions and detailed diagrams.

What is a Ported Sub Box?

A ported sub box is a type of subwoofer enclosure that uses a port to increase the low-frequency output of the subwoofer. The port is a hole in the side of the enclosure that allows air to flow in and out of the enclosure. This air movement helps to create a low-frequency resonance in the enclosure, which results in increased bass output.

Ported sub boxes are often used in car audio systems because they can provide more bass than sealed sub boxes. However, they can also be used in home audio systems.

The size of the port is important for the performance of the ported sub box. The port size should be determined by the size of the subwoofer and the desired frequency response.

The following formula can be used to calculate the port size:

Port Area (in2) = (
(Subwoofer Diameter^2) / 4
) * (Enclosure Volume / 15)

For example, if you have a 12-inch subwoofer and an enclosure volume of 1 cubic foot, the port area would be:

Port Area (in2) = (
(12^2) / 4
) * (1 / 15)

= 10.4 in2

Once you have calculated the port size, you can cut the port into the side of the enclosure. The port should be cut at a 45-degree angle and should be located on the same side of the enclosure as the subwoofer.

How to Calculate the Port Size for a Ported Sub Box?

The port size for a ported sub box is determined by the following factors:

• The size of the subwoofer

How to Port a Sub Box with PVC

Porting a sub box with PVC is a relatively simple process. However, it is important to follow the steps carefully to ensure that the port is properly installed.

To port a sub box with PVC, you will need the following materials:

• A PVC pipe
• A PVC pipe cutter
• A drill
• A saw
• A file
• A sealant
• A subwoofer
• A subwoofer enclosure

Step 1: Cut the PVC pipe

The first step is to cut the PVC pipe to the desired length. The length of the port will depend on the size of the subwoofer and the desired frequency response.

To determine the length of the port, you can use the following formula:

Port Length (in) = (
(Subwoofer Diameter^2) / 16
) * (Enclosure Volume / 15)

For example, if you have a 12-inch subwoofer and an enclosure volume of 1 cubic foot, the port length would be:

Port Length (in) = (
(12^2) / 16
) * (1 / 15)

= 10.4 in

Once you have determined the length of the port, you can cut the PVC pipe using a PVC pipe cutter.

How to Calculate the Port Area for a Subwoofer

The port area for a subwoofer is calculated using the following formula:

A = (3.26 x Fs x Vb) / Sd

• Where:
• Fs is the subwoofer’s resonant frequency in Hz
• Vb is the volume of the enclosure in cubic feet
• Sd is the subwoofer’s surface area in square inches

To calculate the port area, you will need to know the following information:

• The subwoofer’s resonant frequency
• The volume of the enclosure
• The subwoofer’s surface area

Once you have this information, you can plug it into the formula to calculate the port area.

Example:

Let’s say you have a subwoofer with a resonant frequency of 30 Hz, an enclosure volume of 2 cubic feet, and a surface area of 100 square inches.

To calculate the port area, you would plug these values into the formula:

A = (3.26 x 30 x 2) / 100 = 1.99 square inches

So, the port area for this subwoofer would be 1.99 square inches.

Note:

The port area is just one of the factors to consider when designing a ported subwoofer enclosure. Other factors to consider include the port length, port shape, and port tuning. For more information on designing ported subwoofer enclosures, please consult a reputable subwoofer enclosure design guide.

How to Build a Ported Sub Box With PVC

To build a ported sub box with PVC, you will need the following materials:

• PVC pipe
• PVC fittings
• Wood screws
• Wood glue
• A saw
• A drill
• A measuring tape
• A level

Step 1: Cut the PVC Pipe

The first step is to cut the PVC pipe to the correct length. The length of the port will depend on the subwoofer’s resonant frequency and the volume of the enclosure. For more information on calculating the port length, please consult a reputable subwoofer enclosure design guide.

Once you have cut the PVC pipe to the correct length, you will need to cut the ends of the pipe at a 45-degree angle. This will help to create a smooth transition from the port to the enclosure.

Step 2: Drill the Port Holes

The next step is to drill the port holes in the enclosure. The port holes should be located on the front or back of the enclosure, and they should be the same diameter as the PVC pipe.

To drill the port holes, you will need to use a drill bit that is slightly larger than the diameter of the PVC pipe. Be careful not to drill the holes too large, as this could weaken the enclosure.

Step 3: Insert the PVC Pipe

Once the port holes have been drilled, you can insert the PVC pipe into the enclosure. The PVC pipe should fit snugly into the holes, but it should not be too tight.

To insert the PVC pipe, you may need to use a little bit of wood glue. Be careful not to use too much glue, as this could make it difficult to remove the PVC pipe later.

Step 4: Seal the Port Holes

The final step is to seal the port holes. This can be done with a sealant or a gasket. Be sure to use a sealant or gasket that is specifically designed for use with PVC.

Once the port holes have been sealed, your ported sub box is complete!

Tips:

• When cutting the PVC pipe, be sure to wear safety glasses to protect your eyes.
• When drilling the port holes, be sure to use a drill bit that is the correct size.
• When inserting the PVC pipe, be sure to use a little bit of wood glue to help it stay in place.
• When sealing the port holes, be sure to use a sealant or gasket that is specifically designed for use with PVC.

How to Tune a Ported Sub Box

The tuning of a ported subwoofer enclosure is the process of adjusting the port length and port area to achieve the desired frequency response. The tuning frequency of a ported subwoofer enclosure is the frequency at which the port resonates. This is the frequency at which the port will produce the most output.

To tune a ported subwoofer enclosure, you will need to experiment with different port lengths and port areas until you find the combination that produces the desired frequency response. You can do this by using a subwoofer enclosure design guide or by trial and error.

Once you have tuned the
