question about a port

[tsupra98 10+ year member]

so the box i'm building for my 15" L5 can only be 15" tall. but for the port to be tuned at aroud 40 hz it has to be 13.75" long. now everyone has told me to put the sub up and port up. will there be a problem with only having a little more than an inch of space between the bottem of the port and the bottem of the box if i fire the port up?

so you will have 1 1/2 inch of space between the back wall and the port? no

fire the port sideways near the bottom of the box, should yeild better results

shit i just realized i didn't include the thickness of the wood so i can't have the port firing up anyways i don't have enough space that way. any other suggestion on wich way to fire the port??

if it will clear the sub, you could do a 22.5 degree angle and see what that length is.

firing sideways would work. same length
