Hi all.

A Vietnamese friend of mine,
that came to my house/listening room,
sent me this e-mail letter with links to a product that he said
would improve the acoustic of my listenting room.
Any of you have experience with this product?
If not, what do you think about it?

Guy 13

Note:
The links are in Vietnamese,
but a window should pop-up for translation.

hello Mr Guy !

These are the bells that i've told you last time we met.
They are used to absorb the resonances of high freq sounds aroung 6khz to 9khz , and eliminate them. To my ears, they really make some huge changes if carefully set up.

But for your small room, since the listening area is quite limited. I recommend you to have a look at these little things :

 http://www.amthanhvang.com/vi-VN/zone/265/product/642-mig-bo-3-cai.aspx

Place them under your Rega Apollo, because i think that is nearly the main place of your listenning room when the sound gathers when music be played. They will eliminate the physical vibrations and resonances, and widen the sound stage, which is really useful for small auditioning room.

They are made from stainless steel, nikel plated. Their diameters are around 6cm, height is around 4cm. I think it's not so hard for you to find a place to make copies of them

Guy,

The products are from Synergistic Research here in The US.

Whether they work or not, I have no idea.

I think anyone would be much better off downloading something like REW, getting a measurement microphone and taking some room readings to see what is objectively happening in their listening space.

Speaker placement, chair/couch placement at that point is free and would be much better use of time and money than arbitrarily guessing that tweaks like the ones in your links would make things better. If after measuring and tweaking speaker placement you are still not happy I would try acoustic treatments next to make things better. After that, I might try tweaks if they are reasonably priced and generally thought to make an additional improvement. Good luck and happy listening.

Ditto.

Guy, you know what they say... try before you buy!

[Rob Babcock]

The links aren't opening for me but I agree that it would be best to use Room EQ Wizard to see what you need first.  I'm kind of 'old school', and any treatments that don't hew to established acoustic principles will probably be viewed with some suspicion until I see measurable effects.

Hi Hugh.
That product is imported and sold on planet Vietnam.
I've seen it advertised on a local audio hi-end magazine.

Hi murphy 11.
I agree with you, I just posted info/link for that product to share.
I have no intention to buy it, especially at the crazy price.
Thanks for your advices.

Guy 13

[Guy 13]

Guy, you know what they say... try before you buy!

Hi JohnR.
John you know what... ?
I will not even try it, because I have no intention of buy it.
Why I don't want to buy it?
Because, I don't believe in it.
However, I do believe in trying before buying,
but that does not apply to this product.
Thanks for the advice.

Hi Rob.
Thanks for the advice.
My room's acoustic is not that bad, of course, it could be improved,
but for for now, I will keep it that way until my wife wins the lottery jack pot.
However, if she win the jack pot, I will not invest in the acoustic of my listening,
I will take the money to go back to my home country Canada.
That being said: I will now go back to my listening room
and enjoy some nice music on my not perfect sound system,
but good enough for me.

Guy 13

If I posted that link for those bells,
it's mainly to find out if any AC member as tried it, that's all.
Never had the intention in investing in expensive little bells.
I do have some tubular bells,
but their purpose is not to improve the acoustic of my listening room,
but to make beautiful sound when some draft hit them.

Unless someone has been able to break the laws of physics then I can say they will do nothing. All you have to understand is how large a sound wave it and you will quickly understand how these will not work. Unless I am missing how they are used.

Hi Glenn.
From what I saw, look as if there is two ways to use them.
One is under a component, like CD player or turntable.
Two is simple as a bell, but upside down.
You can see pictures on the link.
To me, how can a so small device can make any difference, but according to my Vietnamese friend, it's aimed at 9KHz... ? ? ?
Because when he came to audition my system, he told me that I had a 9KHz peak in my listening room.
He's got better ears then mine.
Well normal, he's around 30  and I am double that.
Anyway, I will wait for more comments.
Thanks for your comments.

I would recommend testing the room before investing any kind of money.

[ricardojoa]

Hi Guy, did your vietnamese friend tell you how much the peak was? High Q or low Q? And it was your room? Not at your listening position?

[Guy 13]

Hi Guy, did your vietnamese friend tell you how much the peak was? High Q or low Q? And it was your room? Not at your listening position?

Hi ricardojoa.
Wow, your (Spanish) name is as long as this one:
Don Alfredo Erodrigo Erodrigez.
What do you mean by how much?
What do you mean by High Q or low Q ?
It was in my listening room which has no special acoustic treatment.
When he told me that there was a peak at 9KHz he was sitting in the listening position, in the sweet spot.
More questions?
Go ahead and shoot them to me, I am ready to answer to the best of my (Limited) knowledge.

Hi Glenn.
Thanks for the link.
There a lot of interesting and informative reading to do on that link.
It will take me some time and when I am done with all the reading I will get back to you, if I have not been run over by a 40 tons Vietnamese truck.
For now, I cannot invest a single $ in my listening room.
You don't know yet that I am on a microscopic budget.

Hey guy, wild guess but it is Portuguese. Yes the traditional portuguese likes long names, usually dual names.
How much? Of course in terms of Decibels, for example was it 5db,10,15...I wouldnt dare to ask how much in terms of money..
Low q or high q meant , if the peak was really centered or was it spread out to adjacent frequencies.
If the peak is in the room meaning, it will peak  no matter where you stand, or was it simply at your LP. It sounds like it in the sweet spot.

Ola senhor Ricardo.
(Did I get that right?
If your answer is NO, then blame Google translate, not me.
I don't know why I mentioned that my Vietnamese friend said
that there was a peak at 9KHz in my listening room.
What he said as no real value, unless it's supported by some measurements
and tests.
His comments were based only from listening from the sweet spot with hos two ears.
Anyway, some time ago I did some (Basic) measurements,
even if many AC members said my measurement were useless,
it however gave me a vague idea of the acoustic of my listening room
and that's the only thing I wanted to know.
I know where are the weak spots and frequencies in my room
and I have no intention of investing money to fix it,
because (Hopefully) soon;
I will be going back to my home country Canada
and any investment would be lost.
So far, I am happy with the sound of my audio system, despite some weakness.
I am not as demanding as many AC members that only want the best of the best.
Not all audiophiles have the same requirements...
Thanks for your comments and sorry if I was not of great help answering your questions.
Xong Roi va Tam biet.

Hey guy no problem. Sounds like you cant wait to return home.
Hope this can be accomplished sooner to you.

Hi Ricardo.
Its been almost 20 years of suffering here on planet Vietnam,
therefore, yes, I cant wait to return home,
even if the return will be very challenging.
