Sensitivity. This is the sound pressure level a speaker produces
at 1 meter (m) when driven with 1 watt (W) of pink noise. Pink
noise is random noise with equal energy per octave. This noise
is either band-limited to the range of the speaker or is a onethird-octave band centered at 1kHz. Sensitivity is measured in
dB/W/m (dB sound pressure level per 1W at 1m). A spec of 93dB/W/m is considered high; 85dB/W/m is low. The higher
the sensitivity, the less amplifi er power you need to get adequate loudness.
