how does an 'Audio Grounding Box' work?

In theory, the large Audio Grounding Box has more materials, more energy and better results. Audio Grounding Box can't replace the grounding wire, only improve the sound quality. The Audio Grounding Box removes interference (EMI/RFI) from the sound system in an independent and direct manner...

[voodooless]

It’s total nonsense.

You do at least get a box of crystals:

Actually, I love it. Get some random chit, throw it in a cute wooden box, attach some copper foil to the contents, a nice gold plated brass banana socket and call it done.

What's in that box? Looks like barbecue coals, crushed glass, ground ginger, and copper sulphate.

 

[voodooless]

ground ginger

I guess that must be the active ingredient…

 

[Joachim Herbert]

It doesn't. Work.

I think that brown stuff is just half a shovelful of sand. The blue stuff looks like that gunk that accumulates in the powder drawer of the washing machine.

otherwise I think you're right.

If there's no improvement in sound you could have a barbeque with the coals and put the sand on your doorstep to stop ice forming in the winter. Use the now empty box for storing old lemonade bottles.

Planet Earth is NEVER the destination for noise, leakage, lost Neutral or ground currents in audio systems (although occasionally it's a parallel path).
So the boxes have no task to perform!

Ding ding ding ding we have a winner!!!!

Although they have worked to spawn a number of hilarious threads here.

 

[egellings]

They don't.

Electrically the copper is parallel to the terminal form an internal loop. Excessive stored charges can be dispelled in this loop. It is like bypass cap in crossover. Not ideal about the crystal between them. Electrically it works but what it is intend for, it is your own opinions. You can get similar result if your amp has ground terminal and your interconnect has ground like phono cable.

The first review I posted was on the Entreq grounding box which I think retails for $3,500. See: https://www.audiosciencereview.com/forum/index.php?threads/entreq-signal-grounding-measurements.476/

Of course it does nothing whatsoever.

What? The other end is not connected to anything so there is no loop of any kind.

I have done a whole video on grounding and why devices like this don't do anything:

It is looped into the Zero-Point energy of the Universe. You can tell by the crystals.

I dunno actually, I just google the diy boxes that commonly found.

Some look like it short or close to short. Even it open. It is AC signal that can be detect at the foil plates end. It ground usually connect to -ve point. Just like you how you prove GR- Research power cord it still energised even the cords is not connect to anything.

Entreq "signal grounding" Measurements

Hello everyone. As some of you know, I signed up for making some measurements of the Entreq "signal grounding" box. If you don't know what that means, you are not alone :). It is a type of device where you connect it to the ground or negative terminal of your audio signals and it is supposed...

You have review it but you can't open the boxes as request. Can't access the copper foil inside to see AC signal being energised in the box.

No one needs you to google for them and post stuff you don't know or understand.

Don't try to make any sense of what kongwee says....it goes nowhere.

For RF there is a "loop", actually, the air is the return path connecting the ends of the dipole antenna formed ;-)
I'm not saying that this would make any difference to the equipment this useless gimmick is connected to, quite the contrary, it's a total scam.

Yeah, but it's oxygen free copper sulfate!
