On
there is a section of demagnetizing a speaker magnet. Is this just a matter of creating a large coil and bursting it with a very large current to create a counter magnetic field to the speakers? (in theory at least)
BTW, I have a speaker that reads lower impedance(or rather DC resistance) than rated. 12ohms vs 16ohms another identical speaker reads 17ohms. These are suppose to be 16 ohm speakers. I'm assuming the coil is shorting out possibly due to chafing? These speakers run in parallel and have a dc resistance of about 7 ohms. What's the electrical and aural issues with using the speaker? This is a tube amp and the amp is designed to run
In the manual it says "You can always have a higher resistance ( 16 ohms, for example ) without damaging results, but too low of a resistance will likely cause problems."
Which suggests I should probably use the 4ohm connector rather than the 8ohm at a cost of output power and whatever aural issues the speaker has?
