could any body show me hoe to do all of the calculations for ported boxes?

It would take me an hour or two to type up how to design a ported enclosure. And that is just the simple basics. Not how to design using T/S parameters...

So r the calculations right? I didnt actually do them myself. Someone else did them.

Yes, with a margin of error @ .4hz. I actually got a net volume of 2.05ft^3. But the change would be minimal.

That is a good design on paper.

Could some body correct me if im wrong but aren't the lengths wrong on either the rear or the sides? If i put the box together like it is now wouldnt i have a 3/4'' gap somewhere? If it is wrong if i changed the rear width to 30'' instead if 28.5 would this cause a change in the internal volume or the tuning?

I just checked the cutsheet, your right. It is off. There are a couple of ways to piece the box together. Here is one

Top/bottom - 30 x 16

Left side - 15.25 x 12.5

Right side - 14.5 x 12.5

Back - 30 x 12.5

Front - 27.25 x 12.5

Here it is with the port piece shown...

i just realized that if i changed the rear diminsion to 30'' i would also have to cange the side to 15 1/4''. Would this change anything. Or i could change the sides to 16''. which i think would be easier. I'm just wanting to know if by chaging these diminsions would i change the tuning and or internal volume?

hey thanks dude like my question is though would it change any of the stated?

No. As long as the port area is not effected, it will not change it. Really doesn't matter how it's put together, as long as the external/internal dimensions stay the same.
