I finally got around to actually designing a ported box for 1 12" Memphis PR.

I played around on reaudio.com playing with numbers and made a box to my specs. And FWIW, you can download the caculator to you computer, by going to the parent directory... http://reaudio.com/speaker_box/

Here is what I have now...

The person I'm making it for listens to mostly rap and hip-hop. What should the box be tuned to?

Memphis's specs 2.00 / 45 / 12.5 x 2 x 19.

Any help would be greatly apprecitated

33-37hz would be nice.

Please pick up a piece of paper or a pencil or even set up something in excel. I don't find that calculator accurate at all.

for the dimensions given I got 2.06ft^3 @ 39hz thats without speaker displacement.
