Not really.  The 8.2ohm is so low compared to everything else in this
circuit that the speaker, series capacitor and 8.2ohm resistor are
essentially a voltage source from the rest of the circuit's point of view.
If there was a resistor in series with the speaker and the emitter, it
would provide some negative feedback, but this one is in parallel with the
speaker (for AC analisys).
