Can someone check this for me?

This is my first ported design.

It should be 2.75 cu. ft. at 32 hz. If I did the math right. I used the sticky posted here and winisd to come up with the port length.

The port is 2.5"x12.5"x27.25"

The outside dimensions are 30"x14"x18.5"

These are pretty much the max dimensions I have to work with.

If someone would check my math and/or offer some constructive criticism, I'd really appreciate it.

If driver displacement is .14 you are right on the money. Your port pieces should be 14.5" and 7.5" long, depend on how to screw them together. (Ex: They could also be 13.75" and 8.25")

Not bad for a first try.

I'm a little off on the net vol. according to the specs it's 0.10 for the pair. (JL 10w0)

I must have rounded something wrong. But, 0.040 shouldn't make that big of a difference, Right?

Thanks for the input.

Right, it won't make any difference whatsoever. Good luck!
