Rocketted sound!

Does anybody knows this crazy stuff: Haliaetus?


Price? Well... hmm, have a sit...
It's 8 to 12 K€...

[Vincent]

Well, coming back to this subject...
What exactly do we need to build such HP?
Some knowledge in acoustic and flows dynamic domain, and a good kraft man to realize it, right?
Or is there any other secret that I miss?

[bsork]

Well, it's (partly) real rocket science, isn't it?

With such prices, they should sound fabulous and in a way I like how they look, although they remind me of some props from old 50s/60s sci-fi movies. Way out of reach for most of us, anyway...

Yes it is real rocket science, but only for the nozzle. I imagine that it's shape has been calculated on the basis of air mass and acceleration. It avoids vortex and loss of energy, specially for low and very low frequencies (high energy). As soon as the shape is calculated, any good turner could make it. Not sure it has to be in aluminum. Maybe stone, marble? Green marble of the Alps, preferentially...
And what about the box? could it be also a by-product of the combustion room? Or just a box?
It seems so simple! Why this price? Because they're good? Ah, crazy men!

Way out of reach for most of us, anyway...

except if I make it for myself. Do you remember the first guitar of Jimmy Hendricks? He just did it. I'll sit my stage on sound rockets and push the START button.

Now you just have to play the Euromillions game.

Now you just have to play the Euromillions game.

I think I would be more lucky in building it by myself. Just trying to gather the right competences.
