so Graphene is both the strongest and most conductive material known
orders of magnitude beyond Aluminum
doesn't that make it ideal material to make true ribbons of ?
and could such a ribbon actually become viable in prosound ?
i am also thinking you could laminate graphene on titanium foil.
titanium is proven as diaphragm material but not very conductive.

Making graphene is relatively easy but to make very large uniform sheets of it is another story. So you are likely to end up with a not so highly conductive graphene coating. The titanium probaby being more conductive per volume than the graphene coating.
Those titanium diaphragms are rigid though, they do not need to elasticly deform like a ribbon will. Titanium is petty brittle though, not as elastic as aluminum. My rough googling tells me that aluminum is 6x better at elastic deformation than titanium (alu 3x steel, steel 2x titanium)
But yes, graphene would be an interesting ribbon / planar material.
One potential problem / challenge would be to connect the terminals to the graphene. It would not be a single solid volume like aluminum but rather many layers of graphene sheets where the resistance between each sheet is lower than the resistance between the sheets. It might be that the inter-layer resistance is low enough that we can ignore it, but it might also not be and in that case we might need some exotic way to connect the sheets at the terminal points.
hmm many opted for this, but the layer is so thin. its quite useless in planars. its all relative. it is most conductive... if you compare 1 atom layer thickness graphene to another material. same for strenght. etc. but if you want a normal impedance... you need allot of layers. witch will make it expensive etc etc. maybe in the future 🙂
But aluminum is still malleable enough, and gold has higher resistivity / weight than copper, which in turn has a higher resistivity / weight than aluminum.
So it would be less efficient than a pure aluminum coil and probably more expensive.
Is there any graphene material that is usable as a structure by its own - and I mean usable in the size dimensions we are talking about. What I gather from the material science and tech industry when they propose that graphene is very strong a stiff, I think this is in the ant or flea dimension - for us its just a coating... perhaps. I think it is basically still overhyped for everyday use of some sort - no?
Graphene is a one (1) atom thick layer of carbon atoms... good luck of building a membrane with that...

"Heavy" at the same thickness as aluminum, but gold is a very malleable material, it can be made several times thinner and it will not break.
After all, the problem with planars with glued coils is that Mylar stretches over time, but metal does not.
Well, the material of the coils also matters, aluminum in this sense does not differ in sound qualities.

i disagree . Kapton has benefits, heat wise for sure. thats where it ends. it sounds worse, its heavy. and there is not much choice in thicknesses with or without glue layer and is insane expensive if you want it thin. also there is allot of yellow......"kapton" that is not kapton on the marked. if you make a planar with alu tape witch has acrylic adhesive. the heat is far less of a problem. compared to alu laminates with polyester backing
