This product will consist of material similar to the QSC waveguide. You are not holding the weight either if have bracing on the inside where the CD just sits on top.
You also should realize that the horn and woofer should not share the same space so there is no pressure involved.
This is one of those times were the discussion has to move on. Im not interested in having 1/2" MORE flange then needed because someone likes the look (I think it looks too PA, no style (18sound gets it, Pyle, the rest do not). If we can save 1" then we should save an 1" with respect to continous waveguide to round over transition.
Just double checked mine:
QSC 152i 10" x 14" = 10 screws, Material thickness .200" semi-rigid plastic
Eminence H290 6.75" x 10.75" = 6 screws, Material thickness .350" rigid abs
If you say 18Sound gets it, then we're on the same page because for their 90x60 horn they use 8 screws and have a .700" flange all the way around.
18Sound XR1496 90x60 10.6 x 10.6" = 8 screws, Material Thickness .300" aluminum
While running the WG/CD in it own sealed compartment with a brace holding the weight of the CD, that or running the WG separate all together, may be ideal, many do not do this. When running sealed I'd rather have all the usable volume I can get and damp the WG.
I think it's a fair compromise to go with the universal option of rectangular with a 1/2" lip, so it suits the most basic screw-it on user, to someone like myself who will be willing to make a jig and route mine down to elliptical, etc..
Considering this is the prototype for which future ones will be cast, I again say it's better to have the material on there now, then to find out you need it later. Since the construction material, thickness, elasticity is unknown for the prototype, or the planned production units, I don't know how anybody could say what will work or not. Therefore I'm going off what I see on similar commercial products.
