Port width help

[Joe X]

The one on the right looks fine to me except 2 6" aeros is not enough port area if you were to push the whole 3400W. The one on the left is trouble, if you place the sub close to the roof is in a way like doing subs up in a trunk car.

Ok, so I'm basically trying to build a small wall now. Can't fit an 18" woofer AND a 10" aero port so I decided to try a slot port. This thing would look pretty incredible in the trunk, I can assure that.

[Joe X]

That's nice, Subs / port forward will work well but you will need to seal off. Can't see your Torres though.

[Inetba]

Well, I want to avoid sealing off, I'm mostly looking for something louder than my current 15" @ 900 watts at 22hz. I'm not looking to compete any time soon, it's mostly for my own amusement.

[Joe X]

If you are not looking to seal off I would bet on the sub up / port back box although you can build both just for fun.

[Inetba]

I'm going to see if I can somehow fit the woofer and a 10" aero port on the same face of the box.

Any dangers having the port really close to the woofer?

[Joe X]

If sub and port are in the same face there's no chance the internal end of the port will too be close to the sub.

[Inetba]

mwahahahaha.

devious thoughts...

I still really like the slot port along the top idea. Still gotta figure out how I'm gonna brace these huge things.

[Inetba]

Also, I read that box thickness isn't as important as bracing? Thoughts?

[Inetba]

Headdesk.

I've been trying to give ​my 18 about 150 square inches of port with a slot port and I started looking at manufacturers websites and the Z18 recommends 104 square inches of port per 18 inch woofer. MUCH less than 150 square inches. So I think I'm going to reduce the port area to 110 square inches so I can more easily tune lower/make the port wider.
