If you want to drive a MOSFET gate at 12V, use a MOSFET gate driver...  Simple.

Anyway what are you actually wanting to do with this speaker?  Square wave buzzer?  Music
reproduction?  What audio volume are you wanting?

If you want efficient circuit with lots of audio volume you need either a push-pull output or perhaps a
class-D bridge output.  Having that resistor load is basically putting lots of power into the resistor
and not much else.
