The more I think about it...my end goal should be to take a selected horn and combine it with the mid cabinet....just like others have down with waveguides and such.

an mid-high array of small drivers (on-wall - which gives additional ~6 dB of dynamic range) and a woofer that is boundary coupled (additional ~12 dB of dynamic range), crossed around 300 Hz, is a viable alternative IMHO

No, not "terribly dissimilar", they both describe incredibly "beamy" horns, reducing from around 90 degree at 1000Hz to less than around 5 degree at 5000Hz and above.

That bad of a horn would be hard to build even if you tried to

Yes laser - when everything get dark (forever?) you're in the sweetspot

They both can't describe beamy horns because one is a 15" woofer lol....A rectangle source is the best I could do for the Vituix dispersion Tool.....surely the real polar isn't so beamy.... the dispersion around where the source width looses directivity is more important to look at here....the beaming of the upper register is exaggerated, surely, by the bad modelling representation.

Question....is it sloppy if I build a box that I would have to destroy to open again?

Don't be afraid of building sloppy prototype, just consider it as one and take most out of it. Then take what you've learned and build the final enclosure which you won't have to open again (if you learnt from the proto). Have fun!
Ps. a box can be destroyed multiple times, just patch it up in between.

The rectangle isn't going to help you at all, the 15" woofer will beam like a laser high enough in frequency. You can see that in the simulation I posted before.

Regarding the chamfer... You know what...I haven't finalized anything yet....I can afford a little more depth on the cabinet...let me see what I can do for the sake of doing it the right the first time....the irony is in how many times I just edited this post.....=)
If you are using MDF or particle board, I would highly recommend Confirmat-style screws. I really like them as they are quite strong and the same hole can be used at least a few times without falling apart. I got mine from Lee Valley.

The "Lo-Root" screws might work, too, but the photos don't exactly inspire confidence.
