I partially understand how a speaker works and in order to decrease its audio output I will have to remove or partially remove the paper which joins the core to the outer body - but will it still vibrate ?. Any suggestions would be most welcome. Hi John, The most probable answer is no as the paper cone centralises the voice coil within the gap between the magnet poles. Without this centring effect the voice coil would just jam against the magnet poles and the output would be extremely low. This effect is noticeable when the voice coil is placed off centre by the paper cone. A low and distorted output is all that occurs as has been noted on some K2 with damaged speakers. Another solution may be to use one of the old type headphones with a metal diaphragm under the screw on earpiece. Another way would be to convert the morse signal to some visual form such as for displaying on an oscilloscope or use a morse reader. Compared to the human brain however, all the morse readers I have tried come off very much second best.
