I think the speaker polarity is not of much concern.
Given the fact that F2 is common source, to me it is inverting. http://www.passdiy.com/pdf/mos.pdf So........yep. |

By that argument, regular amplifiers usually phase invert
several times. ![]() If you treat the red output terminal as + and the black output terminal as - then the signal to the speaker is in phase with the input. |

The black terminal is the active output. The red terminal
is ground.

I see. I simply looked at the amp, without taking the speaker polarity -which indeed can always be inverted- into account.
