RE: Round 80hz exponential horn usage 100 hz to 500 hz

Mahogany is the traditional wood used by patternmakers due to it's stability.
The Sierra-Brooks horns were mahogany. The Edgar Salad Bowls are Poplar.

Many horns have been made of rings of Baltic Birch plywood or MDF.

I used MDF for mine. Can't say if there is any difference in sound, as I don't have a way to compare differences without building more horns.
