Are you going to use the voice coils or not?

People who understand complex box design charge for this type of info.

The only thing I have to say is why?

I modeled one up in Sketch Up for the fun of it to see if I could model whatever the heck I wanted to. I didn't do any measuring beforehand, but I can tell you the box will be fat and huge.

On another note, I just got a job! On 11/11/11, National Metal Day!

it will be huge, temperamental, and overly complex. Using it isobaric loaded will also mean output will be rather low.

Could you remedy that with using a thick enough baffle?
EDIT: I just did the math, I am full on retard.

Yeah a box like that would not only be hard to build, more than likely not worth the trouble. My current favorite box type is the Tline. Get great output if built right.

the whole point of isobaric is sq and space saving. box is small, clean tight, and quiet.

Haha! Ramrod..

Point being, you wont find someone to help you with something like this - and even further, design it for free (if at all). 6th orders take a lot of time and are a large balancing act, another port makes it a big mess.

Give us a better idea of what youre working with, and perhaps a more practical solution can be had.

Just finished the box. Was more complex then I thought, but

so, was the point maximum efficiency from little power? real narrow response?

So, how did it turn out? A quasi tuned enclosure just offers support for the cone below the tuning frequency of the (low tuned) side of the box. Be careful though because too much power below tuning can damage your sub inside the box wherre you can not hear it...
