That port "looks" about right to me. A port in a huge 9 cf enclosure doesn't need to be as long as one in a smaller box to reach the same tuning frequency.

Why are you using the enclosure wall as one wall of your port?

Ah

umm, i wasnt really sure of any other box designs for an 18...that i like atleast

any other ideas?

[AA Havoc Box Design]

I'm still a bit confused at what torres mean...so i cant have vertical port?

i couldnt find the displacement of the 18 havoc for some reason : /

does this look better?

[AA Havoc Box Design]

It's for one havoc, the second cutout is the baffle

ok cool, thanks blurdvision

[AA Havoc Box Design]

so i came up with this... the port doesnt look quite right to me tho...any thoughts?

have yet to figure out how to put the top on top of the rest of the box...haha

[Sundown Sa-8 hitting a 150db!!1]

You will want to place the braces laterally (parallel to the top and bottom of the box) inside the ports. Round them over really well on their leading edges with a router bit and you're good. Actually, you will want to round ALL the peices inside the port.

Also, have you thought of putting small 45s in the corners? You really need to do that, even if it's only a 1.5 inches from the inside. You need something to keep the air flowing through your corners since you have so many of them.

This box should bang if you build it right. Just pay attention to AIRFLOW inside your port for maximum effect. The formulas that you used to predict this enclosure's behavior can't predict turbulence since turbulence is, by definition, chaotic. You can't predict chaos. Only when the airflow is smooth and even can we accurately model a port's performance before we make it!

Good Luck! :hairtrick:

how much space between the the braces?

[New and Improved Box Design]

ok, so ive done some tweaking and this new box is for two dd9510g's tuned at 33hz...im gonna be running 2500+watts a sub.

there will be 45's is all the corner, but im kinda lost as far as bracing : /

could use some help for bracing placement and what to use

[Underpowering Subs]

So I'm pretty new to the car audio "scene"(haha) and was wondering if underpowering damages your sub?

Was lookin at 2 alpine type x 12's and was wondering how much rms in an amp would be recommended for them
