I have some of my lighting setup if you want!
I plan on a doing a demo setup in a copula months. ATM I have srx 725 top boxes to go ontop of four of these sw115 loaded th18's, a fair amount of intelligent lights inc some 1500MW green lasers on a big truss with a 4m wide projection setup underneath and behind the DJ. many details still need to be nailed out but that's the full on setup plan.

Yes I tried the Faital 15HP1030, it sounded great.
That would be displacement limited SPL, and the response shape does not have to be peaky at all, just choose the right driver. Some folks are fine with 1KW, others need 1.21GW
I just received one of my 18sw115 drivers, its a whopper!
The build is still a few weeks away but I might pop it into my old jrx 118s cab to see what it sounds like (anything better than the original is a good start). All parts and fittings have been ordered and just making some final adjustments to the cad file, ready for cnc.
What are the best ways to do a nice grill without restricting the mouth much?

What do you want the grille for?
Metal grilles look nice and can be had at around 70% open. Just put some mounting strips in the mouth and you'll be fine. For structural purposes you can use something that is much bigger and structurally supportive. More wire like in looks. I think Jbell or Art posted a picture a while back.

Ok, I should explain more.
I was somehow under the impression that the grill itself would not do much acoustically but if you were to have extra ply around the entire inner size of the mouth to mount the grill on it would decrease spl or have other detrimental effects.
I would like a grill for the sleek corporate look, protection of the driver, structural integrity or less bracing needed but not necessarily if it is going to have a large sonic impact.
I understand that having double thickness of ply to mount is an option but simply fixing the grill onto the top of the mouth would probably not look nearly as good as the inset one.

With this design a grill all across the opening is very effective in reducing vibrations of the outlet-area... Without it you have losses in efficency and accuracy when using normal 18mm MPX Birch wood. The grill functions as a bracing (if mounted correctly and very tight)... Probably chrpladm is refering to the round grills directly mounted on top of the woofer... this of course makes no sense here....
It has been noted in the past before by Jbell on bracing the mouth of other horns to help rid the resonance. If this was what was wanted than a rebar minimalist waffle style would work best. Extremely strong and supportive. Not very sexy though.
Or you could have one made out of aluminum or steel and just specify the thickness and open area. I would rabbit the mouth edge to mount the grille. BUT you would have to make sure you could rabbit the mouth in all areas first.
And no I am not talking about the grilles you put over the speaker. LOL. Not useable in this application.

For my build, I used the RH-3702 grill from Reliable Hardware and attached it to some 3/4" Baltic birch strips around the inside of the horn mouth (I posted a picture here). I also put some weather stripping between the grill and wood to prevent any vibration. I've had zero issues with this setup and I've been running the sub hard.
On page one there is a cut plan for what looks like v1.
Is there a more updated cut plan anywhere or is that the one to go with?
There are these DWG files:

Have a look at the Max SPL sim. I think the QTS is way too high for a horn and the xmax at 5.5 mm means it won't go very deep or loud.
