To design the box in past I have used autocad, but this box will be a bit more complicated. Do you know what CAD software use Troels Gravesen for design his loadspeakers ?
No, I have no knowledge about which 3D CAD he is using.
I don't have that much contact with him. Once every second year maybe.
I doubt there is any good free 3D Cad around.
Try FreeCAD. Looks a bit like Autodesk Inventor.
Since I have access to IronCAD myself I have no motive to try something else.

Autocad (as long as it is not the LT version) is perfectly usable for 3d design. It will probably not be easy to create complex nurbs shapes, but something like troels' designs should be perfectly feasible.I have used autocad
You could get a free private license for fusion360.
But I can also suggest freeCAD as open source alternative.
Is this because you worry about the upper cross-over frequency for your woofers?Thank you @flex2, I will look,
About MW16TX-8, do you think can be a better cut at 300Hz ? Or would 400 Hz be better as with the MW13TX-8 ?
As flex2 already pointed out.... it depends. I crossed my MW13TX at around 400Hz, But that was because I use woofers that easily reached 400Hz. But my main reason to choose the MW13 instead of MW16, was size, price and ease of cross-over, with the smooth higher response of the 5" midrange/midwoofer. Overall, since I use a very powerful active system, I had plenty of SPL, even with the small midrange.
Point is, using drivers that are more broad-band (reach a bit further than needed) gives you way more freedom(flexibility) to design a complete speaker.

Thank you @digitalthor,
You have right, my aothers reason to use MW16TX-8 instead of MW13TX-8 is the size and the flexibility, the price is the some.
The fact then that you can choose a larger speaker for the same price is a greater incentive. Normally a greater speaker cost more.
If tomorrow I need to choose another woofer instead of Scan Speak 26W/8534G00 for some reason that I cannot now predict, I can, becouse any woofer can be cutted at 300Hz or less.
I suppose that MW16TX-8 can be cut lower than the MW13TX-8 and this matter for me.

I used Scan Speak Discovery 26W several times, it is my favourite value 10" when you are not willing to spend several hundreds more. Plays clear and perfect till xlim without any hearable distortion or noise in 35-40l CB + EQ. For (lots of) more money you will not get better just some more headroom, you just pay then for more linear stroke but not more "quality". Can be used easily without compromises up to 500 Hz, 1kHz might be critical but possible with steep filter. Give it a bucking magnet (+10% BL) and a notch in series for the cone breakup to max it out. Take two per speaker for really nice SPL capability.
