Hello there,
I have been trying to bring up impedance for quasi ribbon and true ribbon speakers. I am at disposal to 4 and 8 ohm amplifier systems but cant quite get the required impedance level for the ribbons i plan to make until I use extremely narrow and super-long ribbons. Most commercial ribbon systems come with a transformer built into the module while the older ones use 2 or 3 ribbon structures that in series cough up the necessary impedance levels.While the impedance of the trafo needs to be lesser than the element its driving, I find the required winding on the secondary a complicated matter. I have comeup with the idea of using double sided PCB with laser tone transfer method which I am fairly new to while I am pretty sure it has its limits.
Would love any and all inputs and suggestions you guys may have.
This is the online resistance calculator I use - Homepage - Ekswai - Ekswai. refer 'PCB trace resistance calculator' . if I use aluminium instead of copper I multiply with 1.58 to get equivalent value.
