SPEAKER POWER CALCULATOR


CUI Devices' speaker power calculator can be used to quickly solve for a speaker’s power, voltage, and impedance ratings when two values are known. To use the calculator, select your drive voltage units from the dropdown, enter your two known values into the appropriate fields, click calculate, and the converted power, drive voltage, or speaker impedance value will be shown. This helpful tool also offers a drive voltage calculator for quick conversion of different drive voltage units. Simply select your unit from the dropdown, enter a value, and the converted units will be instantly populated.

*All voltage signals are assumed to be sine waves
