This is very simple and has many port options. You need Windows (or Parallels for Mac) to run this

Your best bet would be to play around with it. Try different dimensions.

If the port area isnt big enough increase the height/width of the port. Just keep in mind that bigger ports decrease the net volume

but when i increase the size of of the port the hertz go up to like 40

That means that you need to increase the ports length. Keep in mind that you can use decimals in the calculator

well my box is only 20 inches wide and iam already 15 inches deep how much further can i go ?

How high is the box? Of you're doing a slot port or a port with one port wall, you can have the port go up the back wall too.

i wanna do a wall port

[hdorre 1]

A wall is just a big box, so the port can still be "bent"

okay i did this i added 5 inches onto the depth of the box to get 9.69 cubic ft so then i made the port 10 inches by 10 inches and it gives me 12.17 inches sqaured and a new volume of 8.22cubicft does it sounds goood now ?

It'd sound mediocre. Iirc perfectly square ports aren't best. Don't quote me on that though.

You should find a box designer who includes cut sheets, 2D, and 3D dimensions. I dont know of any on here because Im still new. Are you on SMD? I could recommend like 5 guys off the top of my head on there.
