Why not horns?

One last point on the horn loaded Walsh driver used in the German Physiks Unicorn.

The increasingly pistonic operation of the DDD Walsh driver towards the lower end of the sound spectrum is what would produce the pressurization at the mouth needed to enable a horn to be used with a Walsh driver. The horn would not be exposed to sound pressure emitted orthogonally via wave bending in the Walsh driver, so I am pretty sure wave bending alone could not work with a traditional horn design.

Mapman, I won't argue the point of how the GP Unicorn works, but as long as the sound is emitting from a source, I suspect once could attach (a) horn(s) to it, if that's what they wanted to do. Though it would seem to be a contradiction of philosophies in this case.

Ok, enough beating a dead unicorn.

Ha Ha Ha! Dead unicorn, a horse with a horn, get it?

I'm afraid I do get it.:-)

Thanks Macrojack. That was very helpful.
