Thread: The absolutely “best” material for horns construction.
           Reply: What about light metals?  
Some have been used to build box speaker enclosures like aerolam (aluminium alloy I believe), which are pretty dead acoustically, can be moulded and machined, resistent, light (that can be very convenient), and you can finish them  brushed or grainy to avoid reflectivity. I'm a complete ignorant on horns, but whenever I had the space to keep them in a house, I'd like the horns to be "handy" and being able to move them and tweak their placement easily. The big con is probably that it would be very expensive to have your custom horns made, but if some professional builder thought about it...
It's possible that being a metal horn it tended to resonate at audible frequencies, but it could also be that lining it or painting it with some sound isolation compound like Dynamat helped that.

Regards.
