Looks like the infamous drawing error enclosure. The horn exit appears to be sealed.
eheh
Apparently the connecting pieces are there to prevent damage during shipping and are supposed to be removed during assembly.

A poorly designed and BLH built using a very wasteful and not that great constructin technique.
Looks fancy, those smooth curves are counterproductive and the material usage is not in the direction intended so has to be much more heroically built.
3 places where the path is blocked. Likely a rendering/modeling glitch not caught by the rech doing the graphic (and likely knows little of speaker design).

Kits have been available in Japan for quite some time.

The thin sections in three places are removed during assembly.
(It is deformation prevention.)

I used to have access to lots of scrap high grade plywood, and a cnc router.
This would have been perfect for that scenario but pretty wasteful if buying new sheets of wood, since it’s tough to guarantee lack of voids/quality of laminations with most.
Is nice to leave some structure when routering large parts with little area for vacuum, to prevent movement.

The stacked lamination /“latertone” topology represents not only very inefficient material usage, but also incurs a huge amount of fabrication and assembly time as compared to a comparable design of more conventional flat panel construction.
Then of course, there’s the lack of low pass filtering that will be accomplished with the non smoothed corners of manifold/labyrinth designs, such as those that many would recognize by Scott Lindgren.

That’s certainly true, but as someone with no access to the required tools or woodworking skills of any kind, I really wish there were more flat pack options.
You can get flat packs in the US for Frugel Horn FH3's. https://www.bigwoodstudio.net/products/copy-of-frugel-horn-lite-kit

Bob Berner, Big Wood Studio. He is slowly putting together a library of designs he can do. As people add projects his range improves. He is just now taking on the Low-Ken for the 16Ω Alnico PM6 with silver voice coil.

Won’t be cheap. And it won’t be cheap. But worth every penny.

Do you have any cabinet shops in your area?
Have utilized their cnc cutting resources before, sending them a cut file and then picking up the pieces at their shop.

Yes, I think that’s the only option in the US at the moment.
Also went to a local place that quoted me $2K. Another some $1.2K for MDF.
It’s fine, they have skills I don’t and they have equipment I don’t and they have something I want, but honestly it makes me want to give Klipsch money.

I was off writing him an email. His website says this;
And what i said to him (more or less):
Remeber that people, including manufacturers, use MDF because it is cheap.

I've always been intrigued by these designs & some of the variations along the same line. "I can do this!" was my refrain for the longest time..."I'll just get X amount of one-inch MDF, no problem" Then reality sets in rather quickly...so just how big is your full-range anyway? Four inch? Five, Eight? Those panels of one-inch pile up very very quickly...hundreds of pounds/Kilos worth. And, one is going to cut this with a jig-saw?...how long a distance worth of cutting will you be doing?...Fifty-feet worth of wood? Seventy feet? Is your home duty jig-saw going to hold up?, burn up? How many blades would one break trying to cut up all that wood?
No, no and no...don't even try.

Rick, more likely to be machined by CNC routers, or more recently 3D printers. While of course the advantages of the latter is highly efficacious material usage and the complexity of fabrications possible, an acoustically bad design will always be exactly that.
