   A speaker 3 dB more sensitive than another produces double the sound power (is 3 dB louder) for the same electrical power input. Thus, a 100 W driver (A) rated at 92 dB for 1 W @ 1 m sensitivity puts out twice as much acoustic power as a 200 W driver (B) rated at 89 dB for 1 W @ 1 m when both are driven with 100 W of electrical power.
