The BIB calculator says, line length 127 inches, folded height 63.5 inches, internal width 9.4 inches, internal depth 13.3 inches, driver down 27.6 inches from closed end, divider spacing 6.65 inches.

You should take a look at the Terry Cain why the BIB works thread. It is long, but contains essential background on building a BIB and what it looks like. Once you understand the general principal of what a BIB looks like, it is trivial to generate your own drawing - they are all alike and all you need are the dimensions given in the calculator. Basically a tall rectangular box of specified width, depth, and height. Then add an internal divider panel going from the top front edge of the box down until the space between the front and back and bottom is equidistant (equiv to depth/2). Now measure distance from top edge front panel down to where driver position is specified and cut hole for driver mounting. That is the plan and how to make the drawing. These are all internal dimensions.
Good luck - these sound great and you will be amazed at the amount if bass you will get.

Lots of bass yes but if you're sensitive to time delay, then BiB's aren't so great as they spew loads of unwanted noise out into the mid bass region.

The top is open - like a big vent.

Here is a typical schematic of one.

I have actually put them in the boxes for insignia speakers model nsb211 to break them in and I like the way they sound. I am not really looking for a lot of bass but natural sounding. I like the accurate sound they put out right now and the smoothness they have. I do want to build a box that 1 is easy to build and 2 will look nice and make a statement in my listening space. I am open to other ideas

You should look at a MLTL. Smoother more accurate sound with good extension. A mini Karlsonator actually works well with the FE166en according to my sims.
