A 2" port is more suitable. Closed or vented depends on the volume of your box. Check the recommendations here:

You don't need circuit board, just a piece of wood with some hot glue.
2" Home Depot PVC would be fine.

the original box design was with a 3'' port 5.16'' long with a 46hz tuning frequency. In a 1.2 cubic foot enclosure... should I be going after a different design with the 6DB crossover??

The design on the madisound page recommends either a sealed of .25 with an f3 of 90hz or ported that is .5 cubic feet with a 2'' port 6'' long with an F3 of 65hz (much better)

Since this will be going IN the wall, I only have 3.5'' to work with... How would I manage a 6'' long port??

It could be "L" shaped, either a round vent, or a slot vent with a 90 degree bend. Ir there room to go bigger than .5ft^3?

^ I've got the entire wall to work with...drywall is currently removed. I don't care HOW big the box has to be...

I will be moving some of those studs around... My computer will be mounted on the wall right where the old "window" is currently. The speakers mounted on either side. I havn't decided if I'm going to leave the wall exposed, or drywall it yet.

I would like to get the f3 of this speaker down as low as possible. The aura driver has an FS of 55hz. How much lower can you design the f3 of the enclosure for ?? the original design was 46hz. Is that acceptable?

so I lucked out and my left and right wall cavities are almost exactly the same volume. Left is 2.067 and right is 2.045. Could I just use these, seal everything up and slap a baffle on the front??

also, to do the L shaped port, does it matter which way its pointing?

There's really no advantage to going that big sealed, but try it to see what you think of the sound. F3@73Hz & F10@38Hz approx. You able to EQ the bass a bit?
