The Avantgarde horns are made of ABS plastic using a high pressure mold technique to very accurate tollerances. The mold alone would run in the hundreds of thousands of dollars to have made. If anyone offered a horn like the Avantgardes they would be astronomically expensive. That is why you see most horns made of wood. It can be turned on a mill. Problem is; the wood changes shape and sonic quality over time with humidity and aging.
