Alright guys. finally got to work on this project (although my drivers still havnt shown up yets...) BIg thanks to Ricci and JWMBRO for the inspiration on the fold style, JUST A GUY for checking my noob fold skills with akabak.
Final dimensions, 25.7x25.7x20
The driver that will be used in this build is the Faital pro 15 hp1030. The BC 15tbw100, 15sw100, and Dayton pa 385 (kind of) are also good fits. I'm sure there is an 18sound driver that will work but they are too hard to source (affordably) here in the US.
Attached a couple relevant pictures

I honestly didnt lay out cutsheet for this one because i had to cut my 5x5 sheets down at the lumer yard with a handheld circular saw. The 19.25 internal width does play nicely with 5x5 sheets, but the 25.7 x 25.7 sides are not all that efficient (take basically a half sheet for sides alone, with a 9 x 25.7 piece of scrap, and a 5 x 60 piece of scrap ). I also messed up a couple cuts whilst cncing the sides.... yeah... so I'm hoping to get 2 of these out of 3 sheets of BB 5x5 (including all the bracing pictured.

CNC out the braces and the side panel dadoes last sunday. Heres a quick vid for your viewing pleasure.

haha, even I would be jealous of my router skills if it wasnt cncd...
i should have just burnt a piece of bb and made a router template while I was at the shop though... thoughts for next time
Damnit parts express where are my drivers..... 3 to 8 business days my ***.

Hey young man, remember back a few months ago I challenged you to design a tapped horn of your own? Congratulations, you did it! And HaHa, I still haven't got mine done yet, so I hereby admit defeat.
It looks very nice - you did a very respectable job here. Beautiful 3d rendering and that CNC thing is amazing. Are you willing to share your HR files, or the actual dimensions?

I'd like to hold on to them, at least until I get this first one buttoned up and tested, but i'm definitely down to share after that
I probably wouldnt have been able to do it without jwmbros attempt with the fudged dayton specs, but you're right, I did it lol.

Thanks Sine143, I will keep on my eye on this forum thread and watch your progress. I would be particularly interested in you could show the how and why of your testing procedure. I have a lot of experience in testing tops, but not subs, and the whole ground plane subwoofer testing thing I have never done before. Can you help an old man out?
Don't relax too much though, I have two ideas we are going to start building prototypes of in the next week or two. You have beat me to the punch, but the battle is not over. Stand Back - it's going to get LOUD!!!!!

I await your thread.
ground plane testing. get as far away from boundaries as possible, lay down a piece of plywood/mdf etc. put the mic on the ground 2 meters away. If you have a calibrater you should calibrate your mic (I dont). Run room eq wizard or smaart sweeps. done. I'll just be sweeping for response shape, wont be able to tell if its as sensitive at its simmed at.

Nice to see a thread on this. Look forward to your progress. I have quite a few 15's from 18 Sound. I may have to build this. I also have an 18" coming in the next few months. Just cant decide if I want to build the TH18 or Othorn. Either way another build to follow now.
I know my NLW9300's probably are but I am going to use those in my new L/R HT fronts. I have some W750's also which I dont think work because they like a huge cabinet. I'll see what the other models are but I think I will be selling my four W750's anyways. Then I will be getting a few more drivers.(18 9601 or 2400 and another 15)
Unfortunately the 9300 doesnt look that hot. VERY similar to the Dayton (in fact, the dayton has a little bit better excursion control) AND the 9300 has a MUCH lighter cone (aka more distortion at high output).

Thanks for having a look anyways. Most of the designs out there when using my 9300 look very peaky. Will just have to watch this design come together from the sidelines.
Yah I have those plans also. I have built a few different horn builds that didnt pan out. SO I am still thinking of doing the TH18 by Xoc1. If I feel I dont need below 37hz I should be fine. BUT I am really liking the Othorn with the 18 9601.
I am sure I would be happy with a BFM design but I am always curious of other heavy weights that are out there. PLUS I always want way more than I need. 😀
Anyways I dont want to take anything away from your thread here.
