I think the speaker polarity is not of much concern.
Given the fact that F2 is common source, to me it is inverting.

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.
