The maximum power delivered to the speaker would be 215 watt when equivalent resistance is 8 ohm.

According to the maximum power transfer theorem, the power delivered to the load resistor is maximized when the load resistance is same as the series resistance. For its calculation, we take the derivative of the power equation with respect to the load resistance and calculate the critical point.

For an A.C. circuit, the instantaneous power is maximum when the source and load resistances are equal, and when the source and load reactances are equal with opposite sign.

Impedance measures of how much the speaker resists current, the lower the impedance in ohms, the more power the speaker will draw from your receiver.
