## Aero Port Area Formula

The following formula is used to calculate the total area of an aero port.

A = pi*D^2 / 4 * #

- Where A is the total area
- D is the diameter of the aero port
- # is the total number of aero ports

## Aero Port Definition

**What is an aero port? **

An aero port is a space that provides a framework required to enclose sub-woofers within a cabinet.

**What are some advantages of aero ports? **

- Aero ports are much easier to make then slots when done by hand.
- Aero ports let you change the tune of your enclosured without the need to a new box.
- Aero ports are more efficiency then slots.

**What are some disadvantages of aero ports? **

- It can be costly to install aero ports.
- The structure is less rigid with aero ports.
- The sound quality can vary.

## Example Problem

**how to calculate aero port area? **

First, determine the diameter of each aero port.

**In this example, the diameter is found to be 6 inches. **

Next, determine the total number of ports.

**In this case, there are 3 ports. **

Finally, calculate the total aero port area using the formula above:

A = pi*D^2 / 4 * #

A = 3.14159*6^2 / 4 *3

A = 84.822 in^2
