All material shapes have boundaries and how boundaries touch and change speed and direction alter sound . When you layer materials of different types you will alter shear speed and direction. I have done this with many different formula of paint and coatings.
Typically I lay down a layer of blue tape and paint the tape. Cure and listen..then remove and repeat with a different formula. The texture of the paint will also change the laminar flow at the surface. Stick slip on the surface the air will stick to the boundary as if it is wet. I also use magnets to alter material direction of the coating but this can only be done on some material combinations.Tom
I purchased "10" 100 mg vials of graphene oxide. I had to really haggle for 18 dollars a vial.
The person I was dealing with had it priced at 25.00 usd per single 100 mg vial. A 4X8’ sheet of graphene, would be a cool million plus... Super conductor when applied in a VERY thin (single) layer. I torque the connections to reduce the thickness of my concoction. I try to make sure the surfaces are mated (lapped). Then I let (a solvent) evaporate from my mixture.
Graphite maybe? You’re doing some type of shielding?
If it is a ferrous metal, the way you ground and the type of primer, can cause the flake to stand, or lay. I always ground the chassis before paint work.. Unless the paint said NOT to...
Very interesting.. "Radial" you mean like a picture of a sun with the rays radiating from the center? Straight lines from a center point? Complete 360?
I’m kinda thick.. I will ask questions.. :-) Hope you don’t mind.. For some reason the song "Super Freak" keeps popping into my mind. But I keep saying "Super Tweak", it's super tweakie.. Rick James..LOL
" I also use magnets to alter material direction of the coating but this can only be done on some material combinations.Tom"
I can see that and to bad there is no copper magnet. I have seen copper wire jump under capacitor discharge before and maybe there is a way to induce an effect in copper.
" Typically I lay down a layer of blue tape and paint the tape. " Funny how I could miss a simple thing like that very practical idea when doing all this.

" Doesn't RF get through the driver cones? I think what you're hearing has more to do with the paint adding more mass to the cabinet. "
Yes some does get through I am certain but far less than before. I would agree with the mass idea except using differing coatings on different cabinets yielded different results. Now I know the plywood could be variable so I used some out of the same production lot. I think I will weigh these cabinets both before and after to try to determine if they add enough weight to become vibration dampeners.
