si ho una mail con lo stesso video, aspetto una risposta. Ho visto che ci sono diversi tipi di blue tac quale dovresti prendere?
If you think the noise is coming from behind the exciter, you can trace this by using a small bore plastic tube 5mm , holding one end to your ear and putting the other end on or near the offending noise .
You should be able to trace the noise using this method, to its exact location, within millimetres.

Listening with headphones, it sounds very loud as if it is being produced by the panel.
This would suggest to me that it is something to do with the panel ,spider, coil connection.
It is too loud to be something rattling at the back.
Something is loose between the coil assembly and the panel.
Steve.
Is the spider or foot coming loose ?

forse c'è una soluzione come dicevo lo spostamento laterale del corpo dell'eccitatore creava il gracidare, bloccando il movimento verso il basso o verso l'alto o laterale del diffusore con adesivo o isolante limitato della finestra, lasciando il movimento come un pistone, come puoi vedere ora sembra stabile o almeno non così sensibile allo spostamento. Non so ancora se è una soluzione la devo tenere almeno domani come controllo, poi vi farò sapere, sperando che vada bene e magari in futuro possa essere utile a qualcuno. A domani grazie a tutti voi
Except those vibrating strings....for starters....By the way, violins, guitars, pianos have resonance boxes and the sound get's amplified in/through the panels they have, sort of a distributed mode. And, no one is pushing any air.
If you can hear it air is moving.I can't either, so I am still searching for details. The steel structure is too stiff to vibrate, and at 180 degrees to the magnet. The steel spike reminds me of the gramophone needle.
The 2nd video in #7,601 shows another working speaker, but only the front. The bent panel is fixed stiff along the perimeter. I have never seen one. Also, I was so surprised finding this Arcophon speakers in the internet. Well, the sound waves travelling in a panel, and curving even amplifies it was there all the time in the past, even before the cone speaker was 'found', even before Haddock or the French guy were born. Their 'invention' could be the bottom part of the transducer, rather than the top part, that is, the bent curved panel, membrane. Linaeum simply died, and Rubanoide didn't even make it commercially.

Please expand on how you think transducers work. You have had several people try to help you understand the physics behind sound reproduction but you continue to repeat errors. If you can describe your model then perhaps we can clear up a few misconceptions for you all in one go and point you at articles and papers that may help. It will save a lot of time

If ppl keep fixed on to piston pushing the air, well...
Been watching planars being made on tightened mylars, slightest vibrations could be noticed, but no wind in the room...
Incidentally, they too are DMLs, but without the exciter and the pistonic motion.
I suggest you try my zip tie suspension (look back through my posts) - I agree with Steve- too much hanging weight dragging on the exciter.

I must say I'm enjoying the alt-science banter we getting here recently
I'm just waiting for the term aether to pop up

I have the older version DAEX30HESF-4 without the screw and dont have that problem.
When you look at both the old and the newer version of the DAEX30 the newer version voice coil seems to be longer which could mean more sag.
You can fix sag by adding a brace/spine to hold the magnet in place.
Also the mounting disk are pretty thick and adds more mass so the sound will be slightly different then the original exciter without the mounting disk.

pixel1 Looks as though you could fashion the simplest spine ever across that wooden box you have your panel attached in. I used to get that buzzing noise with my DIY exciters until fine tuning them to a spine.
pixel1 Sembra che tu possa modellare il dorso più semplice di sempre su quella scatola di legno in cui hai attaccato il tuo pannello. Ero solito sentire quel ronzio con i miei eccitatori fai-da-te fino a quando non li accordavo bene su un dorso.
