The woofer conductor design must fulfill the following general design:
This explains also why the speaker works, see how the conductors between
each magnet have the current flowing in the same direction, use the
general three finger rule to determine the force on the membrane, change the
polarity and the force is 180 degrees shifted, thus the speaker membrane
move out and in as would be expected...
More on that at a later moment...
And the tweeter design?
