I drew up a few horns in Sketchup a while back intending to print them in sections on a 3D printer. The largest (reasonably priced) "home" printer late last year had a capacity of 12" x 12", so up to 300 Hz horns seemed reasonable in four petals plus throat.

For bass horns, I think a flat-pack could be designed and cut with a CNC router. You may have seen organizations using this method to deliver ready-to-assemble small houses to impoverished populations in poor countries. They literally fit together like a puzzle.

Personally, I chose to make a mold with a CNC router and plasticine clay and plastered eight pieces that fit together. After trial and error factored in, it turned out to be a few year long project for a pair of 100 Hz hypex horns (full space).
