• Im building a box for a Fi bl 12" I want t make it 2.5 cf but I just want to know how the port diamiter should be (how wide , how long ) I want it at 32hz please any help would be great thx!

• Answer:

  if you build a 24 inch x 18 inch x 13 inch box out of 3/4 inch mdf it would put your interior volume at 2.4707 cubic feet. if you then did a port running from the top of the box to the bottom on the same side you mounted the sub on that's 2 inches wide the port would need to go back into the box 20 and a half inches. to put you at 32hz so to answer your question a 11.5 x 2 x 20.5 port in a 24 x 18 x 13 box
