1. ## Brahma Box Help....

Well I received my second brahma and now it's time for the box.....

I have 8.75 cuft. box that all I need is the depth of the port. My port will be 18.5 x 6, and I want the tuning to be 33hz.

This is the box I asked about a while back, it will be fully resined with rounded ports...Also if you think I can go bigger on the box just tell me I have plenty of room...I want it to be loud to the ear, mic I don't care about...

Thanks for the help...

you can use the port equation found on the jl website. all you have to do is solve for lv, the length of the port.

fb=33Hz
av=18.5x6=111in^2
lv=the length of the port in inches
