I am currently looking for 16 and 140 ohm transducers for a circuit that creates a feed back loop with a tuning fork. It is based on ebow. I would like to make certain modifications to get more fundamental( ebow sounds an octave higher), and more volume. One of the two transducers is for capturing sound(microphone), the other is for transmitting sound( speaker, with a magnet as cone). Please explain like you are speaking to a two year old, as I am not too experienced with electronics. Is this a good place to shop for these items?
If you are not experienced with electronics, how did you manage to decide that "16 and 140 ohm transducers" are correct for the project?
Describe the rest of the hardware in more detail, and then you can expect informed advice.
