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

Very important UPDATE about my 3 Helmholtz tubes and about my Helmholtz-Fibonacci room tuner....


I tried straws with 3 dimensions, the better one for the Big Helmholtz PVC plumber tube (8 feet) were regular  straw for the bigger tube and  2 regular straws reduced to half of their normal diameter  on the other 2 smaller tubes.... The opening is closed with plastic cellophane stressed around the mouth of the tube with elastics... These tubes are plumber tubes with few inches diameter....


Results more clarity and astounding difference between the experiments with different diameters of the 1 /2 inches lenght straws...

For the Helmholtz-Fibonacci room tuner i wrapped the mouth of this thin plumber copper pipe with cellophane and elastic and the best results were with a thin hole pierced to the plastic sheet with a toothpick.... Fine tuning of high end audio indeed.... 😁


All this look insignificant and without great consequences at first sight and for the normal reader....Nothing is further from the truth, the impact is amazing and very powerful...

WHY ?

Because if you read the physics about the Helmholtz bottles you will learn how precise is the relation between the volume of the bottle and the lenght of the neck and his diameter linked to the frequency spectrum.... It is critical... When we are near the optimal numbers the impact is huge.... Like changing the amplifier...

My Helmholtz-Fibonacci room tuner is made with 3 sets of 3 pipes which lenght are near the golden ration, then they work all along a set of frequencies in synergetical effect...None of these 9 tubes has the same volume and lenght....

I am flabbergasted by the incommensurate effect  that reducing the diameter of a straw or pinning a hole with a toothpick in a plastic sheet can engender and produce a new level of S.Q.

Audio is fun, cost peanuts, and is akin to paradise...

Dont upgrade anything, listen, think, and embed everything....

Second UPDATE about my 3 Helmholtz tubes and about my Helmholtz-Fibonacci room tuner....




I made some experiment with a few Helmholtz pipes and tubes... I add one directly in front of my speakers 3/4 inches diameter, 3feet 3 inches high....The bass in the room suddenly bloom more and i never enjoy so good bass ever... The room first node is around 43 hertz, my speakers dont go under 45 hertz, and i enjoy now more of the very clear 45 hertz and the upper bass frequencies...

Some miracle happen when i decided to glue a straw on the plastic sheet closing the mouth if this tube centering this straw on the toothpick hole made on it....WOW! It was like 2 helmholtz tubes glued together , the straw is on top of the pipe....

Better imaging and better clarity....


ONE STRAW can change completely the sound of a room.... Think about that.....

WHY?

Because the air in the room is a pressurized heteregeneous complex distribution of springs cells acting on the waves and the Helmholtz tubes are pressurized engines that are able to make the room an ACTIVE participant in the sound perception and no more a boucing sets of passive walls... The S.G. also and the ionizer modify the array of air molecules that act like springs for the waves.... Remember that the waves cross a small room near hundred times each second, in my case 80 times each second....Then the air is like strings of violin under compression...

Acousticians who sells acoustic materials sells you half of the solution only....The passive materials treatment...

The other half are less easy to install and organize like passive acoustic materials can be but they are what make the room an ACTIVATED  part of the sound perception synchronized with the speakers : my grid of S.G. and especially the Helmholtz pipes and tubes grid  with the ionizers....


The room is now active like the speakers are for the creation of the sound experience....ANY small room on par with the speakers are the SOURCE of the sound experience....

Presenting the room like passive walls to be treated is NOT acoustic science it is marketing of easy to install ready made solutions for the acoustic company....

It is my conclusion after this powerful S.Q. increase with ONE straw.....

For sure the mathematical formula to calculate the set of frequencies affected by a particular H. bottle or tube use the neck length and diameter in a crucial way... But this formula was no more an abstraction for me but suddenly a powerful audible modified sound in my experiment, a living experience.....

Like usual the improved S.Q. is sensible and audible in my 2 listening positions, nearfield and the more regular one.....


My best to you all....

LAST UPDATE about all my 18 HELMHOLTZ PIPES and TUBES...


I added one straw for a neck to all my pipes and tubes even to the Helmholtz-Fibonacci room tuner sets....The identical length of the straw on all devices dont change the golden ratio between the pipes...

What i can say?

The relation between the volume of the bottle or of the pipes and tubes to the neck volume and diameter is the KEY....The equation said so.... But listening to the equation by experimenting is a true sckocking experience, the equation is no more dead signs on paper, but suddenly a living animal in the room.... This is the power of acoustic....

You must experiment in your own room...Myself i stumble on the right proportion...

No change of dac or amplifier can replace ACOUSTIC control ever and never in audible impact.... 😊 Save for a very bad gear upgrading to an higher level totally.....The acoustical embedding new control is powerful like that...

After this addition of one straw on all devices, eliminating past shorter neck on them, the results were so amazing....

When you listen to an entire orchestra of brass the timbre differences between, tubas, trumpets, trombones, and the french horns cannot lie....

Astounding, this Gabrielli music by the Empire brass ensemble, which i know by heart, was revealed for the first time in all hues and variation of the brass timbre of each instrument....

Orchestral music and the timbre of each instrument is the BEST test for an audio system....On a single instrument piano is....

I cannot exagerate the huge impact of this longer neck addition to my pipes and tubes used like Helmholtz bottles...


My room is now ACTIVATED, and it is no more to the speakers sound only boucing on the passive walls i listen to, but to a pressurized complex set of engines in synchronisation with the speakers...This is what i call the activation of the room, to make understand the enormous difference between a passive room/walls and an activated atmosphere in the room....

Material passive treatment is important, but active controls by Helmholtz principle exceed it in impact because it is with them that the room is fully activated, with the S.G. grid and the 2 ionizers....


This fact is so much underestimated that if we read acoustitian articles about small room controls, they rarely insist on their importance.... In fact they even dont mention it most of the times....

I guess i am more creative than even some pro..... I have all my time for sure, i no longer work..... 😁

Listening to music is for me life or death.....With no money to spend i just discovered the universal lies in audio about costly gear being the MAIN high-quality source of the experience.... It is completely false, embeddings controls are the key, especially the acoustical one....



I pity all those who spend money on costly dac and amplifier...... 😁😊😎

I best them with 18 straws.....Nobody will ever believe me, i dont believe it myself.....🤑😋🤐😊

Be creative, listen to your ears only, not to reviews or audio consumers....


My best to all.....



Remember that all my audible effects are tested in my 2 listening position, nearfield and regular in my room....

UPDATE on my ionizers grid....





I replaced the costly moskitoefree french device (i will spare it for waiting rooms in pandemic zones) by a low cost very efficient car ionizer , a second one, because my room is like the space volume of at least 3 cars...

Complete audible success... Even if the french device did not ionize with the same internal mechanism than the more regular 20 bucks chinese device, the chinese device is very good, sturdy, in solid aluminum,low noise, but what it give in S.Q. increase indeed  compensate easily the slight borderline audible DB noise of his internal mechanism....

The one i bought are USB powered... It is more practical than battery powered because they work 12 hours a day in my listening room....I listen music a lot indeed....Even reading.... 😊


Here is the exact one i bought and the dealer was very efficient....

For 40 bucks these 2 are very good and i cannot listen music with them "off"....

But if you suffer asthma or respiratory problems, beware, these are ionizer.... Inform yourself before buying...

Another acoustical simple controls for me , and one i could use without modifying it.... But i have a crazy  idea about some addition to it....To be continued later... 😁😊😎😉

Do you prefer listening to music with the ionizers
"on" or "off?"  The tradeoff is the enhanced effect
versus the slight internal noise they generate.

Do you notice a difference in SQ when
you leave them running all the time EXCEPT for
the times you are listening attentively?
