Re: Box expert needed
I get a total box volume of 4.86cu'
Your ports will measure a total of 50" in length. You forgot to subtract the 1" for the face of the box. This will give you 1.01cu' of port displacement.
4.86 - 1.01 - .24 = 3.61cu'
A box with a vol. of 4.4cu', using two ports tuned to 26Hz, the ports would have to be 51" long each. So I guess that this would be out of the question.
Is there any special reason that you want to have two ports??
Keep the box dimension that you have. (I have almost the same thing but I used 3/4".) Put the port on one side. I will be 15" tall x 3" wide x 22" long. This will give you 45sq" of port and tune it to ~30Hz.
