Anyone remember the coin tweak?

Re: nearing Feng Shui

The most mystic tweak (that did nothing not to improve but to even change the sound) was this positive energy ladden foil strips
that this English guy who now lives in Japan sent me for free through self paid mail.

So I thought of a .... paliative. I said that some guru once told a friend (true story) that monuments load their surrounding grounds with tons of positive energy, so it was probable that I had no negative imbalances because I live 10mins walk from the Parthenon in Athens! Hence nothing to treat.
He found it a very reasonable answer.

LOL good anecdote Salas. Has made my morning

Tried and measured

I have tried it out and measured it also.
In some speakers with no good above 10k response it lends some desired brilliance. JA was wright that it did not change the dispersion. Although it changes the resonant behaviour when I runned waterfalls. It adds resonances from 3.5k up to 13k. Depends on the sturdiness of the cabinet. When put the mic right above and perpendicular, I got more HF level than without the coins but it did not alter the dispersion on frontal tweeter axis across a 30 deg arc.

What other strange tweaks have you all heard about doing to spekaers and equipment to improve the sound of things?

What about dangling a ping pong ball in front of a HF driver?

Re: Re: Re: Re: Re: The $1.20 tweak was not a pun

Yes. I seem to recall Sam saying that Canadian coins sounded better.

Try 2 coins of 0,50€.

That's the best tweak in sound quality

I seem to recall Sam saying that Canadian coins sounded better.

One interesting thing about this speaker tweak is that it costs a different amount in different countries. I'd say it works best in canada not only because it may or may not sound better, but because its cheaper to implement making your positive results versus cost of tweak ratio go up ever so slightly.

On the other hand, I wish I knew some easy tweaks of say modifying the front panel of a box to give better dispersion of the HF sounds. For example, look at the shape of all the tweeters of these mackie studio moitors.

Surely the shape of the material around the tweeter helps dispersion... Now how can we do this for DIY using normal woodcutting tools?

[faustian bargin]

how about these coins?

maybe they'd help improve the sound of an iPod or some such.

Ya, I remember hearing something about that once, but never understood what the idea behind it was.............

Well, there has been much discussion about the validity of double blind listening tests, this is one area where I would like to see them applied, as open minded as I strive to be, I just can't accept that placing coins on a speaker is going to make any kind of audible difference with anything.

I read about that here:

Sounds feasible....

my input on that coin tweak.

 

[Timn8ter]

How about a door knob?

 

[kevyjo]

Hey, maybe putting an "ionic breeze" in one's listening room would clean up the midrange.

Hahaha, I clearly remember the coin tweak! It was a joke, the author even said "if you don't like it, you can get your money back!"

The coin tweak won't work unless you first demagnetize your non-magnetic aluminum CDs.
