[QUOTE="Bennett Prescott, post: 215509, member: 4"] I would also really like to do that, Peter! A 300Hz horn is a statement, a new 500Hz horn is a bit more practical. Would be nice to have to go with the eventual smaller DCX driver (shh). The trick is that it can never be justified as a money making product.

Then we had to choose a manufacturing process. A $100K tool would have let us make these out of an OK plastic for $20 or so each, 1000 at a time.
