I see this project as enhancing the value of the property, although I can't see the use of property at all unless you can do what you want w/it without worrying what the next owner will think or want-may as well always just rent if you can't do what you want. As i have done a lot of custom installation of various equipment in numerous venues, I am always tempted to chime in on ventures of this sort. But I'm sure you and your man on the scene can better assess the reality and possibilities of what is in front of you. For myself, I would be tempted to project the mouths of the horns a couple of feet into the listening chamber for visual effect. Sonic considerations might preclude that, but I think I would enjoy the sight of such horns as much as their sound.

Those appear to be pretty large roof rafters, so a suspension system should work if necessary, and you are correct about the compressive support against the ridgepole. I might connect each rafter to the one opposite w/ a board to further stabilize things and relieve some of the pressure from the ridge if things are going to get real heavy. Cable, with turnbuckles(for tension adjustment) would be good for a suspending element.

Back chamber volume adjustment intrigues me, but I am called towards multiple adjustment systems rather than a one time deal and hence my ideas are overcomplicated and unsuitable for your installation. The plastic pipe thing w/the rubber seals is possible as I have a piece which will accept a 4" pipe sliding into it. The other end is threaded and can be worked into a mounting flange which will then bolt to a block of wood as the baffle. I use it as a light shield w/cap on a telescope project I have. The entire telescope mount is 1 1/2" galvanized pipe and allows rotation thru 3 axes, as well as solidity.

I am afraid, but I will continue.
