I think im guna put the port in the front. Are there any advantages/disadvantages of the above design vs this one?

I think the first design is better than the other one you posted. Have you decided which one you are gonna do?

I have no idea if this is right or not.... Kind of a question.

Would it help to put angled pieces in the corners that direct the waves? I'm not exactly sure how sound waves work, but w/ it like that wouldn't it mostly get trapped in that first row? I don't know... Maybe that is completely retarded...

The angled pieces are to reduce port noise. I dont think ill have a problem with it though since i have fairly large port area.

I havnt decided yet... I kinda like the look of having the port next to the sub, as in the second design. I wonder if that would cause more cancellation? I guess i dont know enough about it to know.

I like the second design better because the main chamber has more ideal proportions.

what program did you use to model the response? thats alot of port area for 1 15"

what vehicle?

That's a hell of a lot of port area for a single 15. Bring it down to around 60 sq in.

I used this site to calculate the minimum port area.

the minimum was like 89.5 square inches. I went with 90.75

Its goin in a 99 Isuzu rodeo

55-60sq in is what I'd go with...

Is there a disadvantage of having too large of a port area? the reason i went this big was to reduce port noise, plus thats what the above calculator told me.
