Slot Port To Round Port Calculator

Overview:

Jun 03, 2010 That's really how more port area (such as in a slot port) helps you, by decreasing air velocity through the port. So if your port velocity is 13 m/s with a 100 sq. Inch slot port and 13 m/s with 60 sq. Inches of aero port, there should be no difference. Remember, just like the round port, only use the length that extends into the enclosure when calculating the port’s displacement. Figure N shows the internal and external dimensions of the port. The external dimensions will be used when calculating displacement. Calculating the displacement of a slot port is very similar to calculating.

The formulas used in the calculator create a design that suggests the most maximally flat response in an anechoic environment based on the number of drivers, the thiele small parameters and the allotted dimensions specified in the user’s input fields.

The calculator does NOT take into account the effects of placing the enclosure into the listening environment. This type of enclosure may not be the most suitable option for your application. I recommend reading the articles in the Projects category on box design for further information.

Feel free to check out the other calculators on the site as they may provide the results you are looking for. —> Enclosure Calculators You can also request a totally custom design for your driver(s)/application by filling out the form in the Blueprints Inquiry page.

Port Length Calculator

This calculator will determine what length port to use in your ported enclosure.

Select whether you are using a round or slotted port for you box design.
Enter the number of ports you are using, the internal airspace of your box, then tuning frequency you wish to use, and then hit calculate button.
If you are using a slotted port, select square under port type, then answer yes under are you using a slotted port.
Then under square vent, type in the height and width of the port you wish to use.Then hit calculate.
