A speaker with an efficiency of 100% (1.0) would output a watt for every watt of input. Considering the driver as a point source in an infinite baffle, at one metre this would be distributed over a hemisphere with area 2 π {\displaystyle 2\pi } m 2 for an intensity of 1 / ( 2 π ) {\displaystyle 1/(2\pi )} = 0.159155 W/m 2 .
