Miracles in Audio, by luck, by good choices,by design or by tweaking...

I think that the grid of "Golden strings" activated resonators and diffusor devices create a kind of feed back from the direct sound and with the reflected sound, thanks to the Bell of bells connected to the Schumann Generators....

What i hear comes not only directly from the speakers but from a sound coming from all directions and diffused and resonated through the strings and amplified by the Schumann generators grid...It is what i call ACTIVE ACOUSTIC CONTROLS, and i dont know who else except me use this concept.... :) If you know someone else wrote to me...
PASSIVE ACOUSTIC TREATMENT is not so powerful indeed being passive.... In a small room the active controls make us able to neutralize all the problems linked to the content and geometry of the room....They are my most important discovery....

I am no scientist.... But the changes are flabbergasting indeed....

3 years ago i was looking for the best speakers my money can afford, i even buy a supposed better amplifier than my actual Sansui, another Sansui, and i was not sure about the dac i was just pruchasing....

Like all of us i was in the upgrading race, not knowing the SIMPLE AUDIOPHILE LAWS i paid dearly to learn:



The first law,
which is the most fundamental audiophile law:
" Dont upgrade before embedding it"

Second law:"
There exist 3 embeddings dimensions" : MECHANICAL(resonance-vibrations), ELECTRICAL (noise level of any links and general noise floor of the house), ACOUSTICAL ( the known passive materials standard way and the underestimated active controls ways)

Third law:
"The more uplifting upgrading effects are most of the time linked to the controls of the embeddings dimensions, except most of the times if you go to a higher rung with a purchase of E.C."

Fourth law:
" All electronic components (E.C.) roughly are distributed on a 3 rungs scale of ratio quality/price, and the S.Q. ratio decrease or increase in a non linear way with these 3 steps, (low, medium, high or a Gaussian with a non normal distribution if you wish)"

Fifth law:
" Any upgrade with a new E.C. on the same rung as a past E.C. will result most of the time in a low increase of S.Q. at best if there is one, compared to big increase in S.Q. with a more rightful way to embed the components you already owns"

Sixth law:
" Then, dont upgrade anything before you have rightly embedded all and everything"

Then this circle of laws is closed....

I really tought that my thread was at the end with my last post, and  i really tought that it was not really possible to go further without a very costly upgrading of gear....One day or another we all reach what is called, in french and in english, a " plateau"...

I was wrong i reach another level yesterday and also another one today... It is linked to the acoustical controls...

I will give some idea about the impact, massive impact of active device acoustic controls soon.... It seems nobody knows about that nowhere....Especially those who sells acoustical products.... :)

My best...

UPDATE : "Singing resonators" improvement...

In a room the balance between reflective, absorbent and diffusive surface is the key to a good acoustic...

With all modifications in my audio system and room, i had to create a new equilibrium between all these different surfaces...In particular i reduce the reflective one because they begin to show  too much echoes and reverberations...

I decide after reducing the % of  my reflective surfaces to improve what i keep, mainly 2 set of 6 metal bucket, glued together, lice a triangular 6-cells... In the center of each bucket were an herkimer diamond+ tourmaline bead....There is also copper tape band crossing each other on the aperture of each bucket, and i decide to place micro herkimer diamond+tourmaline beads all along the copper tape at central spots...This gives me a sensational improvement...

Increase of the soundstage and better imaging was the results...

My room is way better than 2 years ago by light years....

:)

What we listen to in a room are "informed waves" created by all the content and geometry of the room....There is no sound in a room that is not informed by the room, never mind the speakers....And the myth that nearfield listening gives to you permission to not treat and control the room is only that, a myth ...

The key point is creating conditions to take advantage of this content and geometry...Even taking advantage of reverberations is possible...

The main error is modifying a room in relation to only one characteristic of the sound, for example bass frequencies...

Sellers who want to profit from crowd of customer, use standardized materials and easy procedural measure on some limited aspect of the sound only... If you sell something it must be easy product and easy formula....But only your ears can speak for you about your room....It cost nothing but you must invest time....
A computer can help but no acoustical program will solve all problems... They applied formulas  after some limited feed back they dont listen to the room like ears...Then you can without even computer do the job....It takes time for sure....But this is a hobby no?

If you want to change your room the only guide is the reaction of your ears to tonal timbre instruments accuracy....Nothing else...Using only some frequencies to guide you is not the ideal path at all....

The acoustic of a small irregular room with a complex content with different acoustical properties is more complex to adjust than a Greek theater or a big musical hall...Some general rules that play their role in these bigger structure must be adjust with these particularities of the small room.... We must discover how to use these particularities or limitations in a positive way...

I create my room by listening, trying to reach timbre accuracy , the best i can, imaging, soundstage also.... The bass so important for many, come after that like a ripe fruit....

My 7 inches driver gives me a bass that is powerful and clear.... I dont think that this is commonly the case from most speakers of this small/medium size ...But in the same room 2 years ago it was not the same bass at all....

If i give to you the confidence to trust your ears, to buy less, and to play more, my goal is reached....

My best to all.....

If you can listen music at relatively low volume with a clear distinction of tonal timbre accuracy, then,
your room is very good now.....Like mine..... :)

It is not the bass frequencies nor the higher frequencies that must pilot and inform the acoustic work in a room, but ONLY the perception of tonal timbre accuracy... The conditions which you will use to improve tonal accuracy will also improve bass.... The contrary is not necessary true, because timbre tonality is more complex and encompassing concept than bass frequencies only.....Average computer algorithm for room are not made on the foundation of timbre perception.... We need ears for that....And we are lucky because we have free one.... :)

Timbre is itself very difficult to define acoustically because of the many factors playing a role in his perception....
