What's the problem with modern proper loudspeaker cabinets decoupling ?

I don't think that decoupling of any kind is going to improve the acoustics of already inappropriate room. The speaker box itself should be designed to be acoustically "dead". In my understanding, the firm attachment of the speaker to the wall is basically going to do more good than any attempt at decoupling.
The question here is, has the unwanted vibration of the cabinet the potential to be more significant than "secondary" vibration of the acoustic waves induced in the walls/floor/ceiling? Or let alone the resonances of the room? I personally don't think so, at least with decently designed speakers.

Isn't it easier to make like this -pics, eventually-!??
All the "wires' are rubber-bands, just in case someone confuses them

Great, but my goal is to minimize space and mass to the ultimate level, without neo magnets.
you don't want the floor to resonate possibly coloring the sound
Every surfrace and object able to be triggered makes its own symphony of THD, this is why i've abandoned the multisub.
decently designed speakers.
A devialet phantom don't need any decoupling by design. Loudspeakers designers known what they do better than anyone here.

Poorly executed idea, I would admit. But I wasn't talking about the way the speaker is secured, just about necessity of firm coupling of the speaker to the environment. Infrasonic decoupling is another thing, but to me the comparison to the microphone support was probably too provocative, because that's a whole lo different story.
 
Hello !
The new roll of PLA is arrived and the printer is at work, the polymer springs will be a tad thinner to optimize the lateral deflexions.
@ andy19191 & czgagi : should i buy contcrete bricks and drill my dektop to build an horizontal wall or will you talk about my topic instead on digressing on masonry.
 
It is extremely complex to explain and simplify, and the mathematical formulations won't help much. each one is a its own level of understanding with its own perception and can take whatever he wants here.
I've intepreted the (slelf damped) polymer blades of the SMR decoupling to a loudspeaker cabinet because the blocks of foam selled with studio monitors are unable to handle a very asymetric weight, some will like, some will dislike... technically it works and its my only matter.
 
You know how it is complex and we have to be rigorous with the procedures in order to obtain a few amount of technical credibility.
I don't have a normalized measurement rig, so everything i can write is nuts, i can say that my desktop is vot vibrating at all (see the test page 2).
The desktop seism magnitude 3.4 is down to zero now and the audible result is subjective.
 
For those who don't understand my design :

Light is on ?

I have the full access to all the functions of my CAD software for free during a few time (end of the year for a non commercial use) because iv'e been a student (AGAIN). For a commercial product, the price of the licences will never be covered by my sellings.
 
Here is a guy who had done some measurements ...... it seems decoupling has almost no effect wrt. low frequencies

What will probably make a lot of/some/a little difference is decoupling the midrange from the enclosure, to ensure the enclosure walls are not transmitting some of the energy at the enclosure resonances, which will probably be in the mid to high-mid
 
What makes a difference is Quality of drivers, how they are mounted on the baffle and the crossover.
The things that make the sound.
Cabinets are braced so they dont vibrate.
That is real basic science to raise resonant frequency of the enclosure.

Otherwise normal rubber feet, stands or pointy thingies are fine.
Even the metal cone magic tings start getting pointless and gimmicky.
They do nothing. The stand is to keep everything stable.

Once the sound pressure enters the room, should we make stands for everything in the room too?
Everything vibrates, everything.
Take a junk tiny speaker from a TV, magical stands wont fix it.
The speakers make the sound, not the stands.

The door speakers in my car sound fine as well, no stands.
Any resonance issue is solved with the known methods.

And with standard box builds even those methods get stretched to annoyance here.
