You could do something like this :

1) Have the horns built (either right there in the living room or off site, it makes no difference), and have the builder include a large hook or attachment point at the exterior (back side) of the mouth at all four corners of each horn

2) Cut a hole in the ceiling a little larger than the size of the mouth for each horn

3) Now the tricky part : With pulleys located in the attic and the horn standing on its mouth and driver-end pointing up through hole, attach ropes to all four corners of the horn and, with the help of friends or paid workers, lift each horn vertically until flush with ceiling (don't forget to take photos!)

4) Secure horns to building's structure

5) Finish off the edge of the holes in the ceiling (I would not make the transition between mouth and ceiling completely seamless, as the horn will move and a crack will result; use a foam, rubber, or felt gasket)

Of course if the driver-ends are going to protrude past the roof of the hose, you'll want to have the roof modified first.
