When using round or slot ports, it is important to use either a file or a piece of sandpaper and round off the inside edges of both ends of the port to minimize the likelihood that your port would make whistling noises (caused by air moving rapidly over a sharp edge, like. H = height of slot port w = width of slot port d = diameter of equivalent round port so to compute the 'diameter' of the port as a function of the slot height and width i would use: (using the + obviously) This makes sense to me because given any port length L, the total volume of the port will be the same. Oct 24, 2019 In case there are too many variables with height and width of a slot port to make a calculator, all you need to do is convert the round port to a slot or square port with the same surface area. For example, a 6 inch round port has a surface area of 28 square inches. This will be the same as a port. Next, you enter either an inside diameter for the tube you are using if you want a circular port, or the inside dimensions of the square port you are going to build into your box (make sure you click the 'Slot Port' button if you are designing a slot port - if you don't understand the difference between a square vent and a slot vent, click here.

Overview:

This is a calculator for designing a L-Slot Vent Bass Reflex Enclosure. 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.
