Not ignorance, perhaps a lack of knowledge, you are willing to learn so the ignorant part goes away, just young. In theory if you have more audio output the current thru the coil goes up, field increases, less distortion, in practical use the field produced is not equal to a good ceramic or alnico magnet so it all balances out in the end. At one time several companies made stand alone speakers that had fixed power supplies to power field coil of the speaker, not very efficient but they sounded OK, they were quickly replaced when better magnets became available. The field coil was also used as a filter choke for the power supply in conjunction with hum bucking coils that ran the speaker drive in opposite polarity to the field coil to cancel the hum caused by the ripple in the field coil B+, this was a way to cheat on the size of the then expensive and unreliable filter capacitors. Born in 1945 and still learning.
