It looked like this ->

Take a gulag prisoner, drill a hole in his head and insert supertweeter?

I'll bet that experiment went something like this:

Interrogator: Can you heeear it?
Prisoner: No...
Interrogator: Ve hav vays to make you hear... (shows him a picture of what happened to the last guy, with all the scars)
Prisoner: Oh yes! I can hear it now! Would you believe it sounds so much like 8kHz??? Wow!
Interrogator makes a note: "Human brain samples audio at 192 kHz"

Absolutely fantastic!

The ultratweeter works in the GIGAHERTZ range, and it is supposed to be connected to an audio amp??
How many audio amplifiers are able to reproduce 1 Ghz? And how much music is recorded at 1Ghz?

Ahh... yes of course, that special cable that comes with that ultratweeter

Got to have a couple of these tweets, what about a group buy?

Just discovered this thread and your thoughts mirror my own immediate reaction as I read through the so called synopsis.

I'm betting this thing doesn't even have the wires inside connected. Its probably just a sealed(for a reason ) lump of wood.

Hi all

Now that is funny, people wonder why HIFI is view as the land of snake oil when there are so many things like this around. Not that these doodads don’t work, its just that like other magic stuff, you have to believe in them for them to work, to “hear the improvement”. Fortunately the psychological principal of “buyers remorse” give the mfrs an advantage when someone has spent a weeks wages on some special audio trinket, they are more strongly inclined to hear a difference the more they spent..

A “small” technical problem here is that even at 1 MHz, sound in air is absorbed in just a few inches of travel. Even if they had something, which produced super high frequencies, they would never get to the end of the horn throat at 1 GHz.
I should add “even if” they were fed with a signal other than stray RF the cables picked up because there is nothing from a power amp is going that high either. Audio amplifiers all have intentional or stray series inductance which blocks out RF from going in on the speaker terminals.

Want more “air” or “sound stage”, open a window, knock down a wall or (seriously) absorb the reflections that originate close to your speakers.
Better it would be to donate the $300 to a needy cause where some good may come from it than to hand it to people like this who make things worse for serious audiophiles..

Hehe - that was a gewd find.

I've literally been crying tears here reading this thread.

Reminds me how seedy commercial audiophilia is. The one dealer near me (out of business now) used to do Boston Acoustics & Rotel stuff. They used add a bit of additiional hidden subwoofer in their setup when demo-ing there systems.
