How low tell you when my friend comes with our mic.Then i will post measurements. But a gues 400-600hz.Have you made a Jensenribbon 😀 with 0.6my ?.

haha! It's a bit of a different spin with different design & materials (hence my excitement). The things being posted here are definitely an inspiration in that its very cool to see other people getting things accomplished. It's serving as a great motivator for me! I look forward to posting the finished product soon. (Just waiting on some final materials)
Had a chanc on Sunday to try Jensen Ribbon🙂 I'm not shure if the paper I used (5gsm Tengujo tissue) was not too thin, because the tonal balance was not right. But, that might be also due to the fact that I only had ~1mm corrugation on it, as on my normal alu ribbons on which it works just fine but on Alu leaf over paper the corrugation needs to be bigger, like on ABJensen last picture. I've found some RC truck gears which produce corrugation which hold better on paper/alu material. I'm also going to try some weave pattern corrugation that seems to be significantly more rigid than normal one, so maybe that's the answer for superthin ribbons. Will report back.
Btw, I've also tried helper magnets instead steel for return path circuit in the middle of the bar and its well worth try, definetely helps efficiency, I've got no way to measure, but it's noticeable.

Where did you get that wave pleater ?, looks cool. And the nano iron ribbon works, it gives a more solid darker sound.
Crimpers and Corrugator, Paper Crimper and Craft Punch Mate, Strong Arm
Looks like a paper crimper. Be careful as people list these as ribbon corrugators on ebay and mark them up to 3x the price. Don't let them fool you, it's just a paper crimper / corrugator.

Actually, I just used corrugated paper sheet from art supply shop. They come in a variety of flavours😀 and are cheap. You just have to line them up back to back and put your ribbon in between. Do the corrugation slowly otherwise it will wander from side to side and the resulting ribbon will be snaky

From here but be warned it is expensive 10g 200$.

That gives me idea. If you wanted to do Fibbonaci type ribbon that might work to keep the ribbon lined up in the magnetic gap. You'll still need suspension loops ath the back, I think.
hopefully the nano iron isn't too strong, or I would expect it to have attenuate effect
but might be more important if just have some 'calming' effect
somewhat like magnetic oil in a tweeter voicecoil gap
I remember once, it was tried to use magnetic tape from studio tape recorders, as backing foil
but was way too heavy
nano iron is a very interesting alternative
caution, nano stuff could be dangerous to handle

It do attenuate a bit. I due belive your rigth about the calming effekt.A side effekt is I can tilt the ribbon backwards and it is stil in the middle of the magnetic field.
Nano iron is probably some naste stof in your lungs.I pour in toluene before I pour it into contact adhesive.

(regarding nano iron)
I wander if you can dissolve coating from tapes...
