Parallel and Series Power consumption

Suppose you have two 8 Ohms Speakers of 30 Watts each. When connecting these speakers in Parallel,  the resulting impedance of the circuit will be 4 Ohms, but the power consumption for this circuit will double i.e 60 Watts. And if the same speakers are connected in series, then the resulting  impedance of circuit will be 16 ohms, but the power consumption of the circuit will be half of each speakers i.e 15 Watt. Am I right in saying this?  This is irrespective of the Speakers wattage. Could someone correct me if I am wrong.
