Rear mounting Altec MR-931-12 "Mantaray" Model 14 horns?

That had crossed my mind. As well as just making grills. But I need to be able to remove the horn to remove the driver as needed since there isn't a way to easily get to the nuts when it's installed.

I guess grills would be easy... hmmm...

The grill is an option and if swapping drivers is a need then screw the backs on?
options are endless but I’m sure you will make the right choice.
 
I get where you are going with your thoughts on this and reducing the footprint of the horn at the flange. the guys are going to have to nail the cut-out to make sure that white band is either showing or hidden entirely I guess.

You could always front mount and countersink the flange down to make it at lest flush with the front. Gives a nice professional finished look that is easy with a CNC machine doing the cutting. Probably a bit stronger and more stable as well.

Edit: I see your comment above now.

These guys are really good. They work on high-end houses and do all the really trick details. The fine work.

I just heard from him and he just met with his best guy on the top hats. Justin owns a pair of Altec 9842-8D's I sold him, so he has one of the MR horns there with him. They are going to make a test baffle with the 45 degree chamfer and see how it works out. My hope is that it'll work fine rear mounted, but still provide the clearance for a worst case of we just drop the horn in from the front and front mount it if it's ever an issue.

I guess I'll have answers this afternoon. I'll be glad to have the 614's all back togeather soon. The 288/Emilar horn on top was a better system than the stock Valencia's currently sitting in their place. I need to whip up the Vali grills and get them listed for sale. Maybe this weekend I can find time to do that.

Rolling over or tapering the edges should help matters. If you don't like the look of the ply or mdf endgrain where that is done, maybe they can make the fronts solid hardwood so the exposed endgrain is nice.

I don't mind the exposed baltic ply edge. That matches the front of the cabs anyway. Very MCM like a lot of the stuff in my place.
