Port Size - Help Needed.

[chrismcdonald12 0]

K, box dimensions are 35x32x16 externally. Internally this gives me roughly 8.57Cubes. I want to port this to 34hz or so, and i need a min area of 6 cubic feet after displacements, is this possible? I also need to know how many sq inches of port i should need. I am just going to run out and grab 2 sheets of MDF right now so any help would be wonderful. The only confusing part is that the RE calculator keeps giving me ridiculous port lengths when removing the second portion of the L to make it a square. Any port dimension recommendations would be wonderful. Thanks in advance.

what sub(s) are going in there?

With 100 sq. inches of port it needs to be 28 inches long. That will give you 6.4 cubes net, port displacing 1.75 cubes. That leaves .42 cubes for sub displacement. That'll work if you're going for two 15's. If this is for one 18 you can shorten the port to 27 inches and you'll have .3 cubes left for sub displacement and 6.6 cubes of net volume.

Two RE SX 15's. Thanks again for the help, Only reason i need to keep the enclosure so small is so i can pull it out to grab my spare if i need to.
