Any tips on improving design features?

Total Volume: ~6.25ft^3

Driver Displacement: ~.26ft^3

-

Net Volume: ~6ft^3

12in^2:1ft^3

so ~72in^2

-

Port is 4.75"x15.5"

-

Port is ~25" long tuned to ~32hz

*Subwoofer was modeled before I knew what the inside of a subwoofer looked like, too lazy to fix it.

How do you model subs like that? Seems like a lot of work.

But I do see one major flaw. You figured out the port length without taking into consideration the airspace that the port would take up. You need to use the final volume that the sub will see after all displacements(which isn't going to be 6ft^3).

Shouldn't be an issue, the 6 cubes is that big rectangle on top(before it 'chunks down', the port is literally slapped under the box, it makes calculating volume alot easier.

It's not hard, I use a program called SolidWorks, it lets me model individual parts and then combine them. It's SOOOOO much easier than sketch up.
