Testing my folding jig, for making AMT membranes. i use spacing of 1 mm and pleat depth of 9.. a bit to much still comes out rather nice. i should be able to nail this with a lower pleat depth. also would benefit the top end :)
those amts have there connection point there. an extra strip above where the coil curves. to attach there wires :) but they did use a glue from a seringe before the soldering job :)
really good one . looks like the real deal . or close , it might be a good idea to use epoxy glue insted of hot glue for longer shelf life . (and pro standart resault )
@@joppepeelen ya that's the way to go ... for a prototype . but you got somthing that can be more then that , once you get it right you might be able to make money selling some
its plastics, but if i remember correct they where 1mm. i did alter the combs to hold it before glueing , i made them thinner i believe to compensate for it bulging out a little and becoming wider then they should it has been a while since i made them. so cant say for sure. i do mention it i believe in the video what i did. changin the stack of plates is kind of allot of work so im sure i did not alter them haha i could have done, bit like the ADAM amt fold jig i believe
Would having the membrane in tension affect the sound negatively? You could add some more rods on your jig (at both ends), then glue tabs onto the membrane every time you fold it. That way you keep it together and you could tension it too. It would probably make it harder to pull the jig apart and get the membrane off after but it could be worth a try. If I’m not making what I mean very clear I’ll draw it up and send it to you Facebook.
joppe peelen You definitely could try selling tweeters. All they need is a finished front panel and some 3d printed case. And prices for good tweeters are quite high. Your ribbon ones that can play from below 2kHz, are quite unique. This way you might get funds for the loudspeakers production.
Rigid epoxi (A-B) is the solution!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J1-5IvkrNQc.html, you need stiffness to avoid the damp of that gooey silicon, that´s obvious.
