Default help with diamond audio d9 12 box

so i need to get a box built for my two d9s and army kyle gave me the info on the box as diamond audio gives the design on the box. im not really good at boxes by anymean and im asking for help. http://www.diamondaudio.com/PDF/curr...dEnclosure.pdf here is the specs and he said to have it tuned a little lower. how do i tune it lower while staying at the current cu ft, he said its very musical box and i listen to everything but i love my lows i gotta have the lows but with everything esle. i had a jl w7 13 tuned to 30 hz and it hit so low i liked that but it didnt play everything. got two sundown sa 10s tuned to 35 hz and it hit the mid range but not the lows what so ever sold them two weeks later. i dont wanna waste money on getting a box built and not liking it and have to do it again. i have a 97 civic ex all my subs where faced back and port back and it hit hard and nice. when my kids not in the back i have the seats down. i guess the question what should i tune to and how to adjust the design

You don't have to use that box design, its just an idea.

D6 12s+3,000 watts=some windshield flex - YouTube

that's rocking decaf with that exact box.

diamond says 1.75 cube per sub on the D9s with one port 4" dia by 16 long lol

which will give you 35hz.

I didn't build it, I had someone else do it lol.


I mean you could, but I mean you don't need a complicated box for these, they work well in various boxes. I ran D3 12s in box that was 1.5 per tuned to 36. It sounded great, go nasty low on only 1k rms. With the amount of power I'm running I wouldn't tune any lower.

A simple aero port would be fine imo run a single 8
